Unconstructed state routes in Arizona

Below is a list and summary of the unconstructed state highways in the U.S. state of Arizona. Some are currently proposed while the others have been since cancelled prior to being constructed.

State Route 30

State Route 30
Location: Phoenix

State Route 30 (formerly State Route 801), also known as the I-10 Reliever, is a planned state highway in the southwest parts of Phoenix, Arizona and nearby suburbs. It will connect the southern terminus of Loop 303 with the South Mountain leg of Loop 202. It is planned as a controlled-access freeway to relieve heavy traffic congestion experienced along Interstate 10 in the area.

State Route 50

State Route 50
Location: Phoenix to Glendale

State Route 50, also known as the Paradise Parkway, was a proposed urban freeway through Glendale and Phoenix. Originally proposed in 1968 as SR 317,[1] the freeway would have run east to west, connecting the future State Route 51 and Loop 101, while running roughly parallel to, and 4 miles (6.4 km) north of, I-10 in the vicinity of Camelback Road. The proposed freeway was reassigned as SR 50 in 1987.[2] As the proposed freeway would have crossed through largely developed land and densely populated neighborhoods, it proved to be both extremely expensive and highly unpopular. The route was eventually struck from state planning maps[3] and all land acquired for right-of-way was subsequently sold, the funds being used to pay for other transportation projects.

State Route 76

State Route 76
Location: San Manuel to SR 77

State Route 76 was a proposed state highway in eastern central Arizona, United States that would have connected State Route 77 and San Manuel. There was a planned extension to Benson which would have been State Route 176. It was shown on state maps in the 1970s but was never built. It would have followed the San Pedro River on its entire length.

U.S. Route 93T

U.S. Route 93T
Location: Kingman to Wickenburg

U.S. Route 93T was a proposed temporary extension of US 93 following US 66 and US 89 from Kingman to Wickenburg while the final route of US 93 was to be constructed through Wikieup. The idea was abandoned in 1937, the same year it was proposed. The proposal for US 93 to be extended past Kingman towards Phoenix was denied by the AASHO also in 1937. It wouldn't be until 1965 that US 93 would exist south of Kingman.[4]

State Route 176
Location: San Manuel to Benson

State Route 176 was a proposed state highway in eastern central Arizona, that would have connected Benson and San Manuel before reaching State Route 77. It was shown on state maps in the 1970s but was never built. It would have followed the San Pedro River on its entire length.

U.S. Route 193

U.S. Route 193
Location: Sacaton to Picacho

U.S. Route 193 was a proposed U.S. Highway highway that would have taken over the route of SR 87, SR 187 and SR 84 between Sacaton and Picacho, via Casa Grande. It was proposed by the Arizona Highway Department as a branch of a proposed extension of US 93 at the time. By 1937, the route was briefly redesignated US 93A before the proposal was subsequently dropped. The proposed extension of mainline US 93 was denied by the AASHO the same year.[4]

State Route 380

State Route 380
Location: St. Johns to New Mexico

State Route 380 was a proposed state route that was never constructed in the eastern part of the state of Arizona. It was proposed, starting in the town of St. Johns and would have ended at the New Mexico state line. It shows up on some state maps during the 1970s, but was never built. The road proposed is currently a dirt ranch road. In St. John's, it would have begun at a junction with U.S. Route 180, a child of U.S. Route 80.

State Route 487

State Route 487
Location: Flagstaff to SR 87

State Route 487 was a proposed state route that was never constructed in the north-central part of Arizona. Arizona Department of Transportation was considering adding it to the state highway system in the early 1970s between Flagstaff and State Route 87 near Happy Jack. It did show on state maps during the early 1970s but was never added to the state system and the route disappeared in the mid to late '70s. The road currently exists today as Coconino County Road 3.

Interstate 710

Interstate 710
Location: Tucson

Interstate 710 (I-710) was proposed to follow the current day alignment of the Kino Parkway, an at-grade parkway, between Broadway Road and I-10 in Tucson, Arizona, but it was never built. This freeway, if built, would have served the Downtown area, the University of Arizona campus and the industrial area between the railroad and I-10; an extension to Tucson International Airport.[5] It first shown on a Tucson map in 1971. Strong community opposition to freeways in Tucson was a major reason for cancellation of the project; the Tucson area has long been opposed to the rapid urban sprawl since.[6]

US Bicycle Route System

Future US Bicycle Routes in Arizona include USBR 66, 70, 79, and 90.[7]
