Highway system

Interstate 10 (I-10) is the southernmost cross-country highway in the American Interstate Highway System. I-10 is the fourth-longest Interstate in the United States at 2,460.34 miles (3,959.53 km), following I-90, I-80, and I-40. This freeway is part of the originally planned network that was laid out in 1956, and its last section was completed in 1990.

Interstate Highway System United States highway system

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System or Interstate, is a network of controlled-access highways that forms part of the National Highway System in the United States. Construction of the system was authorized by the Federal Aid Highway Act of 1956. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico.

Interstate 90 Interstate across northern US

Interstate 90 (I-90) is an east–west transcontinental freeway, and the longest Interstate Highway in the United States at 3,020.54 miles (4,861.09 km). Its western terminus is in Seattle, at State Route 519 near T-Mobile Park and CenturyLink Field, and its eastern terminus is in Boston, at Route 1A near Logan International Airport.

Interstate 80 Interstate from California to New Jersey

Interstate 80 (I-80) is an east–west transcontinental freeway in the United States that runs from downtown San Francisco, California, to Teaneck, New Jersey, in the New York City Metropolitan Area. The highway was designated in 1956 as one of the original routes of the Interstate Highway System. Its final segment was opened to traffic in 1986. It is the second-longest Interstate Highway in the United States, following I-90. The Interstate runs through many major cities including Oakland, Reno, Salt Lake City, Omaha, Des Moines, and Toledo, and passes within 10 miles (16 km) of Chicago, Cleveland, and New York City.


I-10 stretches from the Pacific Ocean at State Route 1 (Pacific Coast Highway) in Santa Monica, California, to I-95 in Jacksonville, Florida. Major cities connected by I-10 include (from west to east) Los Angeles, Phoenix, Tucson, El Paso, San Antonio, Houston, Baton Rouge, New Orleans, Mobile, Tallahassee, and Jacksonville. About one-third of its length is within the state of Texas, where the freeway spans the state at its widest breadth.

Pacific Ocean Ocean between Asia and Australia in the west, the Americas in the east and Antarctica or the Southern Ocean in the south.

The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by the continents of Asia and Australia in the west and the Americas in the east.

California State Route 1 state highway in California, United States

State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At a total of just over 659 miles (1,061 km), it is the longest state route in California. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.

Santa Monica, California City in California, United States

Santa Monica is a beachfront city in western Los Angeles County, California, United States. Situated on Santa Monica Bay, it is bordered on three sides by the city of Los Angeles – Pacific Palisades to the north, Brentwood on the northeast, West Los Angeles on the east, Mar Vista on the southeast, and Venice on the south. The 2010 U.S. Census population was 89,736. Due in part to an agreeable climate, Santa Monica became a famed resort town by the early 20th century. The city has experienced a boom since the late 1980s through the revitalization of its downtown core, significant job growth and increased tourism. The Santa Monica Pier and Pacific Park remain popular destinations.

Between its west terminus in Santa Monica, California, and the major East Los Angeles Interchange, I-10 is known as the Santa Monica Freeway. The Santa Monica Freeway is also called the Rosa Parks Freeway for the segment beginning at I-405 (the San Diego Freeway), and ending at I-110/SR 110 (the Harbor Freeway). The segment between the East Los Angeles Interchange and the city of San Bernardino, 63 miles (101 km) long, is called the San Bernardino Freeway. Other names exist for I-10. For example, a sign near the western terminus of the highway in Santa Monica proclaims this highway the Christopher Columbus Transcontinental Highway.

East Los Angeles Interchange interchange in California

The East Los Angeles Interchange complex is the busiest freeway interchange in the world, with its southern portion handling over 550,000 vehicles per day. The northern portion, called the San Bernardino Split, is often considered a separate interchange. The interchange was named the Eugene A. Obregon Memorial Interchange, to honor U.S. Marine Corps Medal of Honor recipient Eugene A. Obregon.

Rosa Parks African-American civil rights activist

Rosa Louise McCauley Parks was an American activist in the civil rights movement best known for her pivotal role in the Montgomery bus boycott. The United States Congress has called her "the first lady of civil rights" and "the mother of the freedom movement".

Interstate 405 (I-405) is a major north–south Interstate Highway in Southern California. The entire route is known as the northern segment of the San Diego Freeway. I-405 is a bypass auxiliary route of I-5, running along the southern and western parts of the Greater Los Angeles urban area from Irvine in the south to near San Fernando in the north.

I-10 is known to a considerably lesser degree as the Veterans Memorial Highway, and it is listed as a Blue Star Memorial Highway. In Palm Springs, I-10 is also named the Sonny Bono Memorial Freeway as a tribute to the late entertainer who served both as the mayor and as a U.S. Congressman. Another stretch a short distance east in Indio is proclaimed the Doctor June McCarroll Memorial Freeway.

Blue Star Memorial Highway highway designation

Blue Star Memorial Highways are highways in the United States that are marked to pay tribute to the U.S. armed forces. The National Council of State Garden Clubs, now known as National Garden Clubs, Inc., started the program in 1945 after World War II. The blue star was used on service flags to denote a service member fighting in the war. The program has since been expanded to include Memorial Markers and Memorial By-ways. These markers are used in National Cemeteries, parks, veterans facilities, and gardens.

Sonny Bono American entertainer, musician and politician

Salvatore Phillip "Sonny" Bono was an American singer-songwriter, producer, actor, and politician who came to fame in partnership with his second wife Cher, as the popular singing duo Sonny & Cher. He was mayor of Palm Springs, California from 1988 to 1992, and the Republican congressman for California's 44th district from 1995 until his death in 1998.

June McCarroll is credited by the California Department of Transportation with the idea of delineating highways with a painted line to separate lanes of highway traffic, although this claim is disputed by the Federal Highway Administration and the Michigan Department of Transportation as two Michigan men painted centerlines before her. She was born in Lewis County, New York. She was a nurse with the Southern Pacific Railroad in the early 20th century. According to a historic marker in Indio, California, after a near-collision in her Model T in 1917, "She personally painted the first known stripe in California on Indio Boulevard, then part of U.S. Route 99, during 1917."

The end of I-17 at I-10 in Phoenix

In Arizona, the highway is designated the Pearl Harbor Memorial Highway. The portion through Phoenix is named the Papago Freeway, and it is a vital piece of the metropolitan Phoenix freeway system. This designation starts at Loop 101, near 99th Avenue, and it continues eastward to the interchange southeast of downtown which is the terminus of I-17.

Arizona U.S. state in the United States

Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona shares the Four Corners region with Utah, Colorado, and New Mexico; its other neighboring states are Nevada and California to the west and the Mexican states of Sonora and Baja California to the south and southwest.

Attack on Pearl Harbor Surprise attack by the Imperial Japanese Navy on the U.S. Pacific Fleet in Pearl Harbor in Hawaii

The attack on Pearl Harbor was a surprise preemptive military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Hawaii on Sunday morning, December 7, 1941. The attack led to the United States' formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.

Phoenix, Arizona State capital city of Arizona, United States

Phoenix is the capital and most populous city in Arizona, with 1,660,272 people. It is also the fifth most populous city in the United States, and the only state capital with a population of more than one million residents.

Near Buckeye, the freeway has mile markers posted every 0.2 miles from 112.2 to 110.8 with the interstate shield and direction of travel posted on the westbound lanes. On the eastbound lanes, mile markers from 110.8 to 112.2 do not include the I‑10 shield and direction of travel.

Buckeye, Arizona City in Arizona, United States

Buckeye is a city in Maricopa County, Arizona, and is the westernmost suburb in the Phoenix metropolitan area. The population was estimated at 68,453 in 2017. In 2017, it was the fastest growing city in the US.

From the southern terminus of I-17 to the southernmost junction with Loop 202, the highway is signed as the Maricopa Freeway. This name holds true as well for I-17 from its southern terminus to the Durango Curve south of Buckeye Road. From Loop 202 south to the eastern terminus of I-8 just southeast of Casa Grande, the highway is declared the Pearl Harbor Memorial Highway. The Arizona Department of Transportation also has maps that show it as the Maricopa Freeway, while the American Automobile Association and other sources show it as the Pima Freeway. The latter's name is used on a stretch of Loop 101 from Loop 202 to I-17.

Between I-17 in Phoenix and the I-19 interchanges in Tucson, I-10 is included in the federally designated CANAMEX Corridor, extending from Mexico City to Edmonton, Alberta.

In Tucson, between I-10 mileposts 259 and 260 are interchange ramps connecting I-10 with the northern terminus of I-19.

The highest elevation along I-10 occurs just east of Tucson, 20 miles (32 km) west of Willcox, at the mile marker 320 exit for the Amerind Foundation and Museum. The westbound lanes of I-10 briefly cross above 5,000 feet (1,500 m) above sea level.

New Mexico

View of Lordsburg from US 70 and the junction with I-10 in New Mexico

In New Mexico, I-10 more or less follows the former path of U.S. Route 80 (US 80) across the state, although major portions of old US 80 were bypassed in Western New Mexico's Bootheel and in Doña Ana County. I-10 passes through three Southern New Mexico municipalities of regional significance before the junction with I-25: Lordsburg, Deming, and Las Cruces. Most of I-10 in New Mexico, between Exit 24 and Exit 135, is concurrent with US 70.

At Lordsburg is the western junction of US 70 and a concurrency; the two highways are joined all the way to Las Cruces. Several exits between Lordsburg and Deming are either for former towns (including Separ, Quincy, and Gage) or lack any town at all.

At Deming is the western junction of US 180, which also forms a concurrency with I-10 all the way to El Paso. One mile (1.6 km) north of Deming on US 180 is New Mexico State Road 26 (NM 26) which serves as a short cut to north I-25 and Albuquerque.

I-10/US 70/US 180 continue east to Las Cruces which is the southern end of I-25. US 70 leaves I-10 (prior to the junction with I-25), heading northeast to Alamogordo, passing through the north side of Las Cruces. The junction with I-25 occurs just south of the New Mexico State University campus, on the southern end of Las Cruces. I-10/US 180 becomes concurrent with US 85 at the junction with I-25. I-10/US 85/US 180 then turns south to the Texas state line, crossing it at Anthony.

From the state line with New Mexico (at Anthony) to State Highway 20 (SH 20) in west El Paso, I-10 is bordered by frontage roads South Desert for lanes along I-10 East (actually headed south) and North Desert for lanes along I-10 West (headed north). The interstate then has no frontage roads for nine miles (14 km) but regains them east of downtown and retains them to Clint. In this stretch, the frontage roads are Gateway East for the eastbound lanes and Gateway West for the westbound lanes. All four frontage roads are one-way streets. Gateway East and Gateway West are notable, in particular, for TxDOT's liberal usage of the Texas U-turn at most underpasses of I-10 on this stretch.

I-10 is the western terminus for Interstate 20, and the two highways intersect at Scroggins Draw, about 41 miles Southwest of Pecos, at mile marker 186.

A small portion of I-10 from Loop 1604 to Downtown San Antonio is known as the Northwest Expressway or the McDermott Freeway, while another portion from downtown to Loop 1604 East is called East Expressway or José López Freeway. In Downtown San Antonio, it has a concurrency with Interstate 35, and throughout most of the northwest side of the city it has a concurrency with U.S. Route 87, which begins in Comfort, before turning off and heading east out of the city. Starting in San Antonio, it follows a more direct route of U.S. Route 90, with occasional small concurrences.

In Houston, from the western suburb of Katy to downtown, I-10 is commonly known as the Katy Freeway. This section has as many as 26 lanes (12 mainlanes, eight lanes of access roads, and six mid-freeway HOT/HOV lanes, not counting access road turning lanes) [4] [5] and is one of the widest freeways in the world. The space for the expansion was the right-of-way of the old Missouri-Kansas-Texas Railroad. The section east of downtown Houston is officially known as the East Freeway, although it is widely known by locals as the Baytown East Freeway due to a marketing push by Baytown, one of the largest cities in the Greater Houston Area.

In Beaumont, it is known as I-10 South, south of Calder Avenue, and I-10 North, north of Calder Avenue. It is known as I-10 East from the I-10 curve to the Neches River, which is Beaumont's and Jefferson County's eastern boundary line. Orange County is on the other side. Continuing into Orange County and passing through the city of Orange at the easternmost end of Texas, and located at the base of the Sabine River Bridge is the last I-10 mile marker in Texas, number 880, before entering into Louisiana.

In Lake Charles, Louisiana, a 13-mile (21 km) loop route signed as I-210 branches off of I-10 and goes through the southern portion of the city. In Lafayette, it serves as the southern terminus for Interstate 49. Shortly afterwards, there is an 18-mile (29 km) stretch of elevated highway between Lafayette and Baton Rouge known as the Atchafalaya Swamp Freeway, as it goes over the Atchafalaya River, across the Atchafalaya Basin Bridge, and the adjacent swamps. It crosses the Mississippi River at the Horace Wilkinson Bridge in Baton Rouge. Baton Rouge eastbound is the only portion of I-10 that is essentially one lane. After crossing the Horace WIlkinson bridge two lanes from I-110 South merge with two lanes I-10 East into three lanes with one of the Eastbound lanes quickly becoming an Exit Only lane. After delays, you are back to four lanes and the I-10/I-12 split. Interstate 12 links Baton Rouge to Slidell and bypasses I-10's southward jog through New Orleans by remaining north of Lake Pontchartrain. In New Orleans, a stretch of I-10 from the I-10/I-610 Junction near the Orleans-Jefferson parish line to the US 90/U.S. Route 90 Business (US 90 Bus) Junction is known as the Pontchartrain Expressway . A dip near the I-10/I-610 Junction, to travel under a railroad track, is one of the lowest points in New Orleans, and is highly susceptible to flooding. Pictures of water dozens of feet deep (several meters) during Hurricane Katrina are commonplace. Near Slidell, the final stretch of I-10 through the Mississippi state line is known as the Stephen Ambrose Memorial Highway.

I-310 and I-510 are parts of what was slated to be I-410 and act as a southern bypass of New Orleans. I-610 is a shortcut from the eastern to western portion of New Orleans avoiding I-10's detour into New Orleans' Central Business District.


I-10 in Mississippi runs from the Louisiana state line to the Alabama state line through Hancock, Harrison and Jackson counties on the Gulf Coast. It passes through the northern sections of Gulfport and Biloxi while passing just north of Pascagoula and Bay St. Louis. It also passes right south of the NASA Stennis Space Center. The highway roughly parallels US 90.

The law defining the route of I-10 is Mississippi Code § 65-3-3.

I-10 crosses over the border from Jackson County, Mississippi, and it goes through Mobile County in southwestern Alabama. In Mobile, I-10 is the southern terminus of I-65. In downtown Mobile, I-10 goes through one of the few highway tunnels in Alabama, the George Wallace Tunnel under the Mobile River.

The speed limit of the eastbound approach is posted at 40 miles per hour (65 km/h) because of the sharp downward curve approaching the tunnel. The highway then crosses approximately 8 miles (13 km) of the upper part of Mobile Bay on the Jubilee Parkway, a bridge that local people call the "Bayway". The highway is next to Battleship Parkway. On the other side of Mobile Bay, the highway goes through the suburban area of Baldwin County before passing through Malbis, Loxley, and then on to the Perdido River to cross over it into Florida.

Most of I-10 in Florida travels through some of the least-populated areas in the state. Much of I-10 west of I-295 in Jacksonville has only four lanes. [6]

In Jacksonville, as in Arizona, I-10 is designated as the Pearl Harbor Memorial Highway. Throughout much of Florida, I-10 is also State Road 8 (SR 8), though it is not signed as such. (I-110 in Pensacola is known as SR 8A.) [7]

While the highway has existed as far back as 1957, the last section of the entire route to be completed was a section of the Papago Freeway from both I-17 interchanges (including the Deck Park Tunnel) in Phoenix, which opened in 1990.

Many widening projects have taken place on the interstate in the late 2000s. In Pensacola, Florida, a three-mile (4.8 km) stretch of I-10 was widened to six lanes in 2008. [8] In Tallahassee, Florida, construction was completed in June 2009 on a project to widen a roughly 8-mile (13 km) stretch of I-10 to six lanes (eight in some places). [9] In Tucson, Arizona, all exits between Prince Road and 22nd Street reopened after an extensive, three-year improvement project. I-10 was widened from six to eight lanes, and seven bridges and underpasses have been built to deal with congestion. [10] I-10 from the Interstate 8 interchange in Casa Grande to Marana was widened from four to six lanes from the second half of 2007, to its completion in 2009. Also in Arizona, from Verrado Way in Buckeye all the way to Avondale, the interstate was widened throughout the late 2000s and early 2010s, with an HOV lane added between Estrella Parkway in Goodyear and Loop 101.

Texas formerly shared the highest speed limit in the nation with Utah's test section of I-15. [11] The speed limit along I-10 from Kerr County to El Paso County was raised by the Texas Legislature to 75 mph (120 km/h) in 1999 and to 80 mph (130 km/h) in 2006. However, the nighttime maximum speed limit remained 65 mph (105 km/h), and the daytime truck speed limit was 70 mph (115 km/h). With 70,000 miles (110,000 km) of highway in Texas, the 432-mile (695 km) stretch of I-10, and 89 miles (143 km) of I-20, between Monahans and the I-10 interchange at the cusp of the Davis Mountains, only a small percentage of roads were affected. [12] On September 1, 2011, night-time speed limits were eliminated, and the statutory maximum speed limit in Texas was increased from 75 to 80 mph (120 to 130 km/h).

As far back as the 1990s, Florida and Alabama have considered a connector that would link Dothan, Alabama, with I-10. In 2008, a proposal to make this new highway a toll road and to expedite its construction to complete it in five years surfaced. In 2012, federal funds previously set aside for the connector were allocated to other projects. In 2014, Florida sought bids for a feasibility study. [13] [14] [15]

Between August 27 and September 10, 2015, ten out of 11 Phoenix freeway shootings occurred on I-10. The last incident, on September 10, took place on Loop 202.

In March 2019, Liverpool indie pop band Her's died alongside their tour manager after a collision on I-10 near Salome, Arizona. [16]

Interstate 25 Interstate in New Mexico, Colorado, and Wyoming

Interstate 25 (I-25) is a major interstate highway in the western United States. It is primarily a north–south highway, serving as the main route through New Mexico, Colorado, and Wyoming. I-25 stretches from Interstate 10 at Las Cruces, New Mexico, to Interstate 90 in Buffalo, Wyoming. It passes through or near Albuquerque, New Mexico; Colorado Springs, Colorado; Denver, Colorado; and Cheyenne, Wyoming. The I-25 corridor is mainly rural, especially in Wyoming, excluding the Albuquerque, Pueblo, Colorado Springs, and Denver areas.

U.S. Route 1 Numbered U.S. Highway in the United States

U.S. Route 1 or U.S. Highway 1 (US 1) is a major north–south U.S. Highway that serves the East Coast of the United States. It runs 2,369 miles (3,813 km), from Key West, Florida north to Fort Kent, Maine, at the Canada–US border, making it the longest north–south road in the United States. US 1 is generally paralleled by Interstate 95 (I-95), though the former is significantly farther west (inland) between Jacksonville, Florida, and Petersburg, Virginia. The highway connects most of the major cities of the East Coast—including Miami, Jacksonville, Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, Boston and Portland, passing from the Southeastern United States to New England.

Interstate 35 Interstate from Texas to Minnesota

Interstate 35 (I-35) is a major Interstate Highway in the central United States. As with most interstates that end in a five, it is a major cross-country, north-south route stretching from Laredo, Texas, near the Mexican-American border to Duluth, Minnesota, at Minnesota Highway 61 and 26th Avenue East. The highway splits into Interstate 35E and Interstate 35W in two separate places, the Dallas–Fort Worth metroplex in Texas and at the Minnesota twin cities of Minneapolis–Saint Paul.

U.S. Route 12 highway in the United States

U.S. Route 12 is an east–west United States highway, running from Aberdeen, Washington, to Detroit, Michigan, for almost 2,500 miles (4,000 km). The highway has mostly been superseded by Interstate 90 (I-90) and I-94, but remains an important link for local and regional destinations.

U.S. Route 80 or U.S. Highway 80 (US 80) is a major east-west United States Numbered Highway in the Southern United States, much of which was once part of the early auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the Pacific Ocean to the Atlantic Ocean. Its original western terminus was at Historic US 101 in San Diego, California. However, the entire segment west of Dallas, Texas, has been decommissioned in favor of various Interstate Highways and state highways. Currently, the highway's western terminus is at an interchange with Interstate 30 (I-30) on the Dallas–Mesquite, Texas city line. The highway's eastern terminus is in Tybee Island, Georgia near the interchange of I-516 and US 17 in Savannah, at the intersection of State Route 26, Butler Avenue, Inlet Avenue, and Tybrisa Street, near the Atlantic Ocean. Between Jonesville, Texas and Kewanee, Mississippi, US 80 runs parallel to or concurrently with Interstate 20. US 80 also currently runs through Dallas, Texas; Shreveport, Louisiana; Jackson, Mississippi; Montgomery, Alabama; Columbus, Georgia; Macon, Georgia; and Savannah, Georgia.

U.S. Route 180 Numberd Highway in the United States

U.S. Route 180 is an east–west United States highway. Like many three-digit routes, US 180 no longer meets its "parent", US 80. US 80 was decommissioned west of Mesquite, Texas, and was replaced in Texas by Interstate 20 and Interstate 10 resulting in U.S. 180 being longer than U.S. 80. The highway's eastern terminus is in Hudson Oaks, Texas, at an intersection with Interstate 20. Its western terminus is unclear. Signage at an intersection with State Route 64 in Valle, Arizona 40 miles (64 km) northwest of Flagstaff indicates that the route ends at SR 64, which is consistent with the AASHTO U.S. Highway logs. However, many maps continue the US 180 designation to the south rim of the Grand Canyon at Grand Canyon Village. Signage at the SR 64 intersection as late as 2011 indicated that US 180 continues north concurrent with the route. However, no signage along the route exists past this intersection until SR 64 turns east towards Cameron, Arizona. At this intersection, signage makes no mention of US 180 nor is there any mention at the terminus of SR 64 at US 89.

U.S. Route 90 United States historic place

U.S. Route 90 or U.S. Highway 90 is an east–west major United States highway in the Southern United States. Despite the "0" in its route number, US 90 never was a full coast-to-coast route; it has always ended at Van Horn, Texas with the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas which lasted less than a year, and the signs on that segment were changed to Texas State Highway 54, traveling from Interstate 10 (I-10) at exit 140A and heading to its northern terminus at US 62/US 180.

U.S. Route 281 highway in the United States

U.S. Route 281 is a north–south United States highway. At 1,875 miles (3,017.5 km) long it is the longest continuous three-digit U.S. Route.

U.S. Route 59 US highway that runs from Canada to Mexico

U.S. Route 59 is a north–south United States highway. A latecomer to the U.S. numbered route system, US 59 is now a border-to-border route, part of NAFTA Corridor Highway System. It parallels U.S. Route 75 for nearly its entire route, never much more than 100 miles (160 km) away, until it veers southwest in Houston, Texas. Its number is out of place since US 59 is either concurrent with or entirely west of U.S. Route 71.

U.S. Route 51 Numbered Highway in the United States

U.S. Route 51 or U.S. Highway 51 is a major south-north United States highway that extends 1,277 miles (2,055 km) from the western suburbs of New Orleans, Louisiana, to within 150 feet (46 m) of the Wisconsin–Michigan state line. As most of the United States Numbered Highways ending with "1", it is a cross-country north-south route extending from the Gulf Coast region to the Great Lakes region. Much of the highway in northern Illinois and southern Wisconsin runs parallel to or is cosigned with Interstate 39 (I-39) and much of the route in several states also parallels the Illinois Central Railroad. From LaPlace, Louisiana, Mississippi, to Memphis, Tennessee, much of that portion of US 51 runs largely parallel or is concurrent with Interstate 55 (I-55). The highway's northern terminus is between Hurley, Wisconsin, and Ironwood, Michigan, where it ends with a T interchange at US 2. Its southern terminus is in Laplace, Louisiana, ending at US 61. US 51 travels in the states of Louisiana, Mississippi, Tennessee, Kentucky, Illinois, and Wisconsin.

U.S. Route 54 highway in the United States

U.S. Route 54 is an east–west United States highway that runs northeast-southwest for 1,197 miles (2,115 km) from Griggsville, Illinois to El Paso, Texas. It enters and leaves Texas twice. The Union Pacific Railroad's Tucumcari Line runs parallel to US-54 from El Paso to Pratt, Kansas, which comprises about two-thirds of the route.

U.S. Route 70 or U.S. Highway 70 is an east–west United States highway that runs for 2,381 miles (3,832 km) from eastern North Carolina to east-central Arizona. It is a major east–west highway of the Southeastern, Southern and Southwestern United States. It formerly ran from coast to coast, with the current Eastern terminus near the Atlantic Ocean in Atlantic, North Carolina, and the former Western terminus near the Pacific Ocean in Los Angeles, California. The current Western terminus is at US 60 / SR 77 in Globe, Arizona. Before the completion of the Interstate system, U.S. Highway 70 was sometimes referred to as the "Broadway of America", due to its status as one of the main east–west thoroughfares in the nation. It was also promoted as the "Treasure Trail" by the U.S. Highway 70 Association as of 1951.

U.S. Route 85 highway in the United States

U.S. Route 85 (US 85) is a 1,479-mile-long (2,380 km) north–south United States Highway that travels in the Mountain and Northern Plains states of the United States. The southern terminus of the highway is at the Mexican border in El Paso, Texas, connecting with Mexican Federal Highway 45. The northern terminus is at the Canadian border in Fortuna, North Dakota, where the route continues north as Saskatchewan Highway 35. The highway route is part of the CanAm Highway. Sections of US 85 are considered part of the Theodore Roosevelt Expressway.

Interstate 610 (I-610) is a freeway that forms a 38-mile-long (61 km) loop around the inner city sector of the city of Houston, Texas. Interstate 610, colloquially known as The Loop, Loop 610, The Inner Loop, or just 610, traditionally marks the border between the inner city of Houston and its surrounding areas. It is the innermost of the three Houston beltways, the other two being Beltway 8 and State Highway 99, of which various segments are under construction or planning.

Interstate 110 (I-110) is a 0.9-mile (1.4 km) Interstate spur route in El Paso extending from Interstate 10 (I-10), south along U.S. Highway 54, turns west then turns south into Mexico. I-110 provides access from I-10 to the Bridge of the Americas, which spans the Rio Grande to connect with Avenida Abraham Lincoln in Ciudad Juárez, Mexico. I-110 is currently the only three-digit Interstate to connect directly with Mexico, and one of only two to connect to an international border, the other being Interstate 190 in New York.

Interstate 10 (I-10) is a transcontinental Interstate Highway in the United States, stretching from Santa Monica, California, on the Pacific Ocean, to Jacksonville, Florida. The segment of I-10 in California runs east from Santa Monica through Los Angeles and San Bernardino before crossing into the state of Arizona. In the Greater Los Angeles area, it is known as the Santa Monica Freeway and the San Bernardino Freeway, linked by a short concurrency on I-5 at the East Los Angeles Interchange. I-10 also has portions designated as either the Rosa Parks Freeway, the Redlands Freeway, or the Christopher Columbus Transcontinental Highway.

Interstate 95 (I-95) is the main Interstate Highway of Florida's Atlantic Coast. It begins at a partial interchange with U.S. Highway 1 (US 1) just south of downtown Miami, and heads north past Daytona Beach, through Jacksonville, and to the Georgia state line at the St. Marys River near Becker. The route also passes through the cities of Fort Lauderdale, West Palm Beach, and Titusville.

Interstate 10 (I-10) is the major east–west Interstate Highway in the Southern United States. In the U.S. state of Texas, it runs east from Anthony, at the border with New Mexico, through El Paso, San Antonio and Houston to the border with Louisiana in Orange, Texas. At just under 880 miles (1,420 km), the Texas segment of I-10, maintained by the Texas Department of Transportation, is the longest continuous untolled freeway in North America that is operated by a single authority. It is also the longest stretch of highway with a single designation within a single state. Mile marker 880 and its corresponding exit number in Orange, Texas, are the highest numbered mile marker and exit on any freeway in North America. After widening was completed in 2008, a portion of the highway west of Houston is now also believed to be the widest in the world, at 26 lanes. There is a wider section in China on the G4 Beijing–Hong Kong–Macau Expressway; however, that section is a toll plaza approach.

Interstate 40 (I-40) is a major east–west Interstate Highway in the United States, stretching from Barstow, California, to Wilmington, North Carolina. The segment of I-40 in California is sometimes called the Needles Freeway. It goes east from its western terminus at Interstate 15 in Barstow across the Mojave Desert in San Bernardino County past the Clipper Mountains to Needles, before it crosses over the Colorado River into Arizona east of Needles. All 155 miles (249 km) of I-40 in California are in San Bernardino County.

U.S. Route 90 in Texas highway in Texas

U.S. Route 90 is a major east-west highway in the U.S. state of Texas with large portions of it running concurrently with I-10. US 90 begins at I-10 in Van Horn, travels through San Antonio and Houston, and continues on into the state of Louisiana.
