Site Navigation Arizona Colorado Idaho Montana Nevada New Mexico Utah Wyoming     U.S. Highway 60 - Arizona U.S. Highway 60 was extended into Arizona on November 20, 1930. The tale of US 60 is wrapped with the Becker Brothers who worked tirelessly to get another transcontinental highway through Arizona in the late 1920s. The route of US 60 replaced Arizona 74 (first incarnation) from Ehrenberg east to Wickenburg, and followed US 89 from Wickenburg to Florence Junction. From Florence Junction, US 60 replaced Arizona 73 (on a new alignment) to Hon Dah (McNary) and Springerville, then US 260 (US 70) from Springerville to New Mexico. US 70 was multiplexed with US 60 from Ehrenberg to Globe between 1935 and 1969. Between 1949 and 1952, a number of sections of U.S. 60 between Superior and Globe were realigned and cleaned up to reduce the number of curves and make the road safer. In 1974, US 60 was truncated at Brenda, where it splits from Interstate 10 in western Arizona. In 1992, US 60 was rerouted from the historic Van Buren Avenue/Mill Avenue/Apache Blvd/Main Street alignment to follow Interstate 17, Interstate 10 and former Arizona 360 through the Phoenix metropolitan area. Grand Avenue (U.S. 60) was modified in 2004 to add grade separated interchanges between Thomas Road/27th Avenue and Loop 101. When constructed, all of the intersections were six way intersections. The Superstition Freeway (former Arizona 360) was built in phases between 1970 and 1992. The first section, from I-10 to Mill Avenue, opened in 1970, followed by Mill Avenue to Price Road in 1975. Price Road to Dobson Road was completed by 1977, followed by Dobson Road to Country Club Drive in 1979. Country Club Drive to Gilbert Road was completed in 1981, followed by Gilbert Road to Val Vista in 1983. Val Vista Dr to Power Road opened in 1985, with the remainder opened by 1992. The Supersition Freeway is the protoype for the rest of Phoenix's freeways, with the road between 2 and 20 feet below grade, with sound walls and berms to hide the elevation of the freeway from surrounding neighborhoods. The Superstition Freeway was widened in 2000 from Interstate 10 to Val Vista Drive, and in 2007 from Val Vista Drive to Ellsworth Road.
