Interstate 70 (I-70) is a major east–west Interstate Highway in the United States that runs from I-15 near Cove Fort, Utah, to a park and ride lot just east of I-695 in Baltimore, Maryland. I-70 approximately traces the path of U.S. Route 40 east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major cities, including Denver, Topeka, Kansas City, St. Louis, Indianapolis, Columbus, Pittsburgh, and Baltimore. The sections of the Interstate in Missouri and Kansas have laid claim to be the first Interstate in the United States. The Federal Highway Administration (FHWA) has claimed the section of I-70 through Glenwood Canyon, Colorado, completed in 1992, to be the last piece of the Interstate Highway System, as originally planned, to open to traffic. The construction of I-70 in Colorado and Utah is considered an engineering marvel, as the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate Highway System, with an elevation of 11,158 feet (3,401 m).
Interstate 29 (I-29) is an Interstate Highway in the Midwestern United States. I-29 runs from Kansas City, Missouri, at a junction with I-35 and I-70, to the Canada–US border near Pembina, North Dakota, where it connects with Manitoba Provincial Trunk Highway 75 (PTH 75), which continues on to Winnipeg. The road follows the course of three major rivers, all of which form the borders of US states. The southern portion of I-29 closely parallels the Missouri River from Kansas City northward to Sioux City, Iowa, where it crosses and then parallels the Big Sioux River. For the northern third of the highway, it closely follows the Red River of the North. The major cities that I-29 connects to includes Council Bluffs, Iowa; Sioux Falls, South Dakota; and Fargo, North Dakota.
Interstate 35 (I-35) is a major Interstate Highway in the central United States. As with most primary Interstates that end in a five, it is a major cross-country, north–south route. It stretches from Laredo, Texas, near the Mexican border to Duluth, Minnesota, at Minnesota State Highway 61 and 26th Avenue East. The highway splits into I-35E and I-35W in two separate places, the Dallas–Fort Worth metroplex in Texas and at the Minnesota twin cities of Minneapolis–Saint Paul.
Interstate 49 (I-49) is a north–south Interstate Highway that exists in multiple segments: the original portion entirely within the state of Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, three newer sections in Arkansas, and a new section that opened in Missouri. Its southern terminus is in Lafayette, Louisiana, at I-10 while its northern terminus is in Kansas City, Missouri, at I-435 and I-470. Portions of the remaining roadway in Louisiana, Arkansas, and Texas, which will link Kansas City with New Orleans, are in various stages of planning or construction.
U.S. Route 75 is a north–south U.S. Highway that runs 1,239 miles (1,994 km) in the central United States. The highway's northern terminus is located at Noyes, Minnesota, which connects to the Canadian border, where it once continued as Manitoba Highway 75 on the other side of the now-closed border crossing. Its southern terminus is located at Interstate 30 (I-30) and I-45 in Dallas, Texas, where it is known as North Central Expressway.
U.S. Route 81 or U.S. Highway 81 (US 81) is a major north–south U.S. highway that extends for 1,220 miles (1,960 km) in the central United States and is one of the original United States Numbered Highways established in 1926 by the American Association of State Highway Officials.
U.S. Route 40 or U.S. Highway 40 (US 40), also known as the Main Street of America, is a major east–west United States Highway traveling across the United States from the Mountain States to the Mid-Atlantic States. As with most routes whose numbers end in a zero, US 40 once traversed the entire United States. It is one of the first U.S. Highways created in 1926 and its original termini were in San Francisco, California, and Atlantic City, New Jersey. US 40 currently ends at a junction with I-80 in Silver Summit, Utah, just outside Salt Lake City. West of this point US 40 was functionally replaced with I-80, and as these segments of I-80 were constructed the western portion of US 40 was truncated several times.
U.S. Route 50 or U.S. Highway 50 (US 50) is a major east–west route of the U.S. Highway system, stretching 3,019 miles (4,859 km) from Interstate 80 (I-80) in West Sacramento, California, to Maryland Route 528 in Ocean City, Maryland, on the Atlantic Ocean. Until 1972, when it was replaced by Interstate Highways west of the Sacramento area, it extended to San Francisco, near the Pacific Ocean. The Interstates were constructed later and are mostly separate from this route. It generally serves a corridor south of I-70 and I-80 and north of I-64 and I-40.
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 the 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. The highway's northern terminus is 9 mi (14 km) north of Lancaster, Minnesota, at the Lancaster–Tolstoi Border Crossing on the Canada–US border, where it continues as Manitoba Highway 59. Its southern terminus is at the Mexico–US border in Laredo, Texas, where it continues as Mexican Federal Highway 85D.
U.S. Route 71 or U.S. Highway 71 is a major north–south United States highway that extends for over 1500 miles (2500 km) in the central United States. This original 1926 route has remained largely unchanged by encroaching Interstate highways. Currently, the highway's northern terminus is in International Falls, Minnesota at the Canada–US border, at the southern end of the Fort Frances-International Falls International Bridge to Fort Frances, Ontario. U.S. Route 53 also ends here. On the other side of the bridge, Trans-Canada Highway is an east–west route while Ontario Highway 71 is a north–south route. US 71's southern terminus is between Port Barre and Krotz Springs, Louisiana at an intersection with U.S. Route 190. For the entirety south of Kansas City, Missouri, US 71 runs parallel and concurrent with the existing and future Interstate 49. North of Kansas City, US 71 runs halfway between Interstate 29 and Interstate 35, which they split in the city at an interchange with Interstate 70.
The Kansas City metropolitan area is a bi-state metropolitan area anchored by Kansas City, Missouri. Its 14 counties straddle the border between the U.S. states of Missouri and Kansas. With 8,472 square miles (21,940 km2) and a population of more than 2.2 million people, it is the second-largest metropolitan area centered in Missouri and is the largest metropolitan area in Kansas, though Wichita is the largest metropolitan area centered in Kansas.

It is mostly in the US state of Kansas, servicing the city of Kansas City, Kansas, but extends into Kansas City, Missouri, as well. The freeway's southern terminus is at a stack interchange with I-35. South of this, the mainline becomes an expressway carrying U.S. Route 69 (US 69).
Interstate 470 (I-470) is a 16.72-mile (26.91 km) loop of the Interstate Highway System that serves to link southeast Kansas City to Independence via Lee's Summit in Jackson County, Missouri. The western terminus of the freeway is at the Grandview Triangle interchange with I-49, I-435, U.S. Route 50 (US 50), and US 71 while the northern terminus is a cloverleaf interchange with I-70. The freeway travels west to east through southern Kansas City, curving toward the north at the Lee's Summit Municipal Airport and becoming concurrent with Route 291 as the highway travels north toward Independence.
Interstate 29 (I-29) is a north–south Interstate Highway in the Midwestern United States that begins in Missouri. It travels through the Kansas City and St. Joseph metropolitan areas before exiting the state and entering Iowa. Almost all of I-29 in Missouri lies in an area called the Platte Purchase that was not originally part of Missouri when the state entered the Union in 1821.
Interstate 70 (I-70) in the US state of Missouri is generally parallel to the Missouri River. This section of the transcontinental Interstate begins at the Kansas state line on the Intercity Viaduct, running concurrently with US Route 24 (US 24), US 40, and US 169, and the east end is on the Stan Musial Veterans Memorial Bridge in St. Louis.
