Arizona State Route 101, or Loop 101, (spoken as one-oh-one) is a semi-beltway encompassing much of the Phoenix Metropolitan Area in the United States. It connects several suburbs of Phoenix, including Tolleson, Glendale, Peoria, Scottsdale, Mesa, Tempe, and Chandler. Construction began in the late-1980s and was completed in 2001. Additional general purpose lanes and a high occupancy vehicle lane (HOV) are being constructed along the eastern stretch of Loop 101 from Scottsdale to Chandler, starting at Princess Drive to Loop 202 (the Santan Freeway).

Loop 101 has interchanges with almost all area freeways, including: Loop 202, US 60, SR 51, Interstate 17, and Interstate 10 along its 61-mile (98 km) route.

Stack interchange

A stack interchange, or colloquially butterfly junction, is a particular, free-flowing type of design for interchanges, meaning grade-separated road junctions. It is referred to as a directional interchange in the American Association of State Highway and Transportation Officials Policy on Geometric Design of Highways and Streets.

State Route 202 or Loop 202 is a partial beltway looping around the eastern areas of the Phoenix metropolitan area in central Arizona. It traverses the eastern end of the city of Phoenix, in addition to the towns of Tempe, Mesa, Chandler, and Gilbert, and is a vital route in the metropolitan area freeway system. Loop 202 has two currently officially designated sections along its route; the Red Mountain Freeway and the Santan Freeway. The Red Mountain Freeway runs from the Mini Stack Interchange in Phoenix with Interstate 10 (I-10) and State Route 51 (SR 51) in Phoenix to the SuperRedTan Interchange with U.S. Route 60 in Mesa, and the Santan Freeway runs from there to an interchange with Interstate 10 (I-10) in Chandler. A third section currently under construction, the South Mountain Freeway, will run from there to Interstate (I-10) in western Phoenix.

U.S. Route 60 in Arizona highway in Arizona

U.S. Route 60 (US 60) is an east–west United States Highway within Arizona. The highway runs for 369 miles (594 km) from a junction with Interstate 10 near Quartzsite to the New Mexico State Line near Springerville. As it crosses the state, US 60 overlaps at various points: I-17, I-10, SR 77, SR 260, US 191, and US 180. Between Wickenburg and Phoenix, the route is known as Grand Avenue. From Tempe to Apache Junction, it is known as the Superstition Freeway.

Loop 101 has various names along its route:

Route description

Loop 101 begins as the Agua Fria Freeway west of Phoenix in Tolleson at a three-level interchange with Interstate 10. From that point, it heads north entering Phoenix then Glendale, passing State Farm Stadium and Gila River Arena. Continuing northward through Peoria, it passes the Peoria Sports Complex before entering northwestern Glendale and heading east just past the Arrowhead Towne Center mall. Loop 101 now heads eastward on the Beardsley Road alignment. The freeway enters northern Phoenix, and at milepost 23, Loop 101 intersects Interstate 17 near the Deer Valley Airport, 15 miles (24 km) north of Downtown Phoenix.

Interchange (road) road junction, typically using grade separation

In the field of road transport, an interchange is a road junction that uses grade separation, and typically one or more ramps, to permit traffic on at least one highway to pass through the junction without interruption from other crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets.

In the U.S. state of Arizona, Interstate 10 (I‑10), the major east–west Interstate Highway in the United States Sun Belt, runs east from California, enters Arizona near the town of Ehrenberg and continues through Phoenix and Tucson and exits at the border with New Mexico near San Simon. The highway also runs through the cities of Casa Grande, Eloy, and Marana. Segments of the highway are referred to as either the Papago Freeway, Inner Loop, or Maricopa Freeway within the Phoenix area, and the Pearl Harbor Memorial Highway outside metro Phoenix.

State Farm Stadium Stadium in Glendale, Arizona

State Farm Stadium, formerly known as University of Phoenix Stadium, is a multi-purpose football stadium located in Glendale, Arizona, west of Phoenix. It is the home of the Arizona Cardinals of the National Football League (NFL) and the annual Fiesta Bowl. It replaced Tempe's Sun Devil Stadium as the Valley of the Sun's main stadium. The stadium is adjacent to the Gila River Arena, home of the Arizona Coyotes NHL team.

Continuing east as the Pima Freeway, it passes through the Union Hills area and then has an interchange with the northern terminus of SR 51 at milepost 29. East of its junction with SR 51, Loop 101 curves south through Scottsdale in the northeast valley on the Pima Road alignment. The freeway curves east and continues onto the Salt River Pima-Maricopa Indian Community just south of Via Linda providing access to Downtown Scottsdale, a large open-air power center called Scottsdale Pavilions, Scottsdale Community College, two casinos, and Scottsdale Fashion Square. Continuing south, Loop 101 encounters an interchange with the Red Mountain Freeway portion of Loop 202 in Tempe at milepost 51, near the campus of Arizona State University. This interchange is partially built over the Salt River.

Casino facility which houses and accommodates certain types of gambling activities

A casino is a facility which houses and accommodates certain types of gambling activities. The industry that deals in casinos is called the gaming industry. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships or other tourist attractions. There is much debate over whether the social and economic consequences of casino gambling outweigh the initial revenue that may be generated. Some casinos are also known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events.

After this interchange, Loop 101 is now the Price Freeway, and interchanges with US 60 at milepost 55 before entering Chandler. Loop 101 provides access to Chandler Fashion Center just prior to concluding at milepost 61 at an interchange with the Santan Freeway portion of Loop 202. [2]

The highway originally was assigned two different route numbers along its path. The Agua Fria Freeway portion was initially designated SR 417; [3] the section along the Pima/Price Freeways was to be SR 117. [4] A portion of Loop 101 between the Superstition Freeway and McDowell Road near Scottsdale had been proposed as the "Indian Bend Freeway" (SR 117) in 1962. [5] The Loop 101 designation was first assigned on December 18, 1987, at which time the South Mountain Freeway and the portion of the San Tan Freeway between I-10 and Price Road were also designated to be part of Loop 101. [6] On July 19, 1991, the proposed South Mountain Freeway was renumbered as part of Loop 202. [7] The San Tan Freeway portion of Loop 101 has never officially been renumbered, though this freeway section has been signed as Loop 202 since its opening.

An exit in Northeast Phoenix at 64th Street started construction in January 2008, and completed construction in the end of Q3 2008. [8] It was finally opened to traffic in May 2015. Construction of Freeway Management System (FMS) for this segment of Loop 101. Using sensors, freeway cameras and the latest technology, the Valley’s Intelligent Transportation Systems keep traffic flowing by providing incident management personnel with information about real-time traffic conditions. Construction was completed on the segment between I-17 and State Route 51 in September 2009.

In 1990, after several years of negotiation with the Salt River Pima Maricopa Indian Community, the state of Arizona paid the tribe $247 million for right of way for the eastern leg of the 101 from (north to south) south of Via Linda to the north bank of the Salt River. [9]

The resulting alignment kept all four corners of each interchange along the roughly 7-mile leg on tribal land, allowing the community to control and benefit from development. The tribe formed a development arm, Salt River DevCo, to manage these and other community developable properties. [10]

On August 26, 2010, comedian Robert Schimmel was involved in an accident on the road in Scottsdale in which his daughter was driving; their car flipped onto the side of the road. Schimmel died from his injuries on September 3, 2010. [11]

Speed enforcement

In 2006, Scottsdale installed speed enforcement cameras along its stretch of Loop 101 to combat the high fatality rate along its section of freeway. The photo enforcement was based on inductive sheeting on the freeway bed located at six fixed positions along the freeway - three in each direction. The photo enforcement was in a trial phase, with the trial ending in December 2006. In January 2007, the program was authorized by Arizona Governor Janet Napolitano to resume in February 2007. [12]

There had been much criticism of the program after its inception. For instance, in May 2006, a vehicle was allegedly clocked traveling at 147 miles per hour (237 km/h) on Loop 101. Scottsdale police arrested Lawrence Pargo soon afterwards. According to the manufacturer Hyundai, [13] the vehicle the suspect was driving had a centrifugal governor, and was only capable of traveling 137 mph (220 km/h). [14]

The system was calibrated to ticket anyone traveling 76 mph (122 km/h) or greater, as 65 mph (105 km/h) was the predetermined speed limit. The system was also designed for night time use and utilized equipment with a high intensity flash and full motion video capture to take pictures of fast-moving objects. [15]

Money from a typical $162 ticket went to the following:

Photo enforcement along Loop 101 ended in 2010. [16]

Interstate 17 (I-17) is an Interstate Highway located entirely within the U.S. state of Arizona. I-17's southern terminus lies within Phoenix, at Interstate 10, and its northern terminus is in Flagstaff, at Interstate 40. The majority of I-17 is known as the Arizona Veterans Highway. In the Phoenix metropolitan area, it is mostly known as the Black Canyon Freeway, however the southern 4.16 miles (6.69 km) is part of the Maricopa Freeway. The portion of the highway south of Cordes Lakes was built along the alignment of SR 69, while the northern part was built along old SR 79's alignment. I-17 is one of the most scenic Interstate Highways as it gains more than a mile in altitude between Phoenix at 1,117 feet (340 m) and Flagstaff at 7,000 feet (2,100 m). The highway features several scenic view exits along its route that overlook the many mountains and valleys found in northern Arizona.

State Route 85 is a 128.86-mile-long (207.38 km) state highway in the U.S. state of Arizona. The highway runs from the United States-Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as San Diego. SR 85 between I-10 and I-8, as well as I-8 between SR 85 and I-10 in Casa Grande, is touted as a bypass of the Phoenix area for long-distance travelers on I-10.

Arizona State Route 51 freeway in the Phoenix metropolitan area

Arizona State Route 51 (SR 51), also known as the Piestewa Freeway, is a numbered state highway in Phoenix, Arizona. It connects Interstate 10 just outside Downtown Phoenix with Loop 101 on the north side of Phoenix, making it one of the area's major freeways. It is a largely north–south route and is known for traversing the Piestewa Peak Recreation Area. The peak was named after Lori Piestewa, the first Native American woman to die in combat in the U.S. Military. Prior to this time, the freeway was known as the Squaw Peak Parkway, a name considered offensive by many Native Americans. Rapid growth and increased traffic demand on the east side of Metro Phoenix made the Piestewa Freeway necessary.

Arizona State Route 143, also known as SR 143 and the Hohokam Expressway, is a north–south and access-controlled freeway in Maricopa County, Arizona, that runs from a junction with Interstate 10 at 48th Street in Phoenix to McDowell Road. The only other major junction along the 3.93-mile (6.32 km) route is with Loop 202, which is located one half-mile south of McDowell Road and the northern terminus.

State Route 153, also known as SR 153 and the Sky Harbor Expressway, is a former state highway in Maricopa County, in the U.S. state of Arizona, that ran from the intersection of 44th Street and Washington Street in Phoenix south to University Drive. It was a controlled access arterial expressway, with a speed limit of 45 mph (72 km/h), lower than the standard freeway speed of 65 mph (105 km/h). Route 153 was a north–south route that skirted the eastern edge of Sky Harbor International Airport, and along with SR 143, SR 153 served a portion of East Valley residents with access to the airport. Many motorists used SR 143 instead, because of its quick access to and from Interstate 10 and Loop 202. The freeway did, however, provide a direct link to office developments in the Southbank commercial project in east Phoenix with the city of Tempe.

State Route 989, also known as SR 989, is an unmarked state highway in Oro Valley, Arizona, that consists of a 2-mile (3 km) stretch of Tangerine Road west of State Route 77.

Arizona State Route 303 highway in Arizona

Arizona State Route 303, also known as Loop 303 or Bob Stump Memorial Parkway and formerly called Estrella Freeway, is a freeway that serves the northwestern portion of the Phoenix area. The freeway, originally a two-lane rural highway, was maintained by Maricopa County in central Arizona serving the far western suburbs of the Phoenix metropolitan area until 2004 when the Arizona Department of Transportation again took the control of upgrading the interim road to a freeway. In 2004, it was renamed "Bob Stump Memorial Parkway" to honor former Arizona congressman Bob Stump.

Salt River Pima–Maricopa Indian Community

The Salt River Pima–Maricopa Indian Community comprises two distinct Native American tribes—the Pima and the Maricopa (Piipaash)—many of whom were originally of the Halchidhoma (Xalchidom) tribe. The community was officially created by an Executive Order of US President Rutherford B. Hayes on June 14, 1879. The community area includes 53,600 acres (217 km2), of which 19,000 remain a natural preserve. The community is a federally recognized tribe located in Arizona.

State Route 30, also known as the Tres Rios Freeway, is a planned state highway in the southwest parts of Phoenix, Arizona, and nearby suburbs. It is planned as a reliever for Interstate 10, and will run through the communities of Avondale, Buckeye, and Goodyear 5 miles (8.0 km) to the south.

State Route 24, formerly State Route 802, also known as Gateway Freeway and Williams Gateway Freeway, is a freeway in the extreme southeastern region of the Phoenix Metropolitan Area. The roadway is planned as a controlled-access highway to move traffic from the southeastern suburbs of Phoenix to planned ones in northwestern Pinal County. It is the lowest-numbered state route in Arizona. The first mile from Loop 202 to Ellsworth Road opened on May 4, 2014. Planning for future sections has been halted until studies for the Pinal North-South Freeway are completed to confirm how the two freeways will intersect.

The transportation system of Arizona comprises rail, air, bus, car and bicycle transport.
