In 2004, Phoenix voters approved a Regional Transportation Plan that includes almost $16 billion for a light rail system, construction of Freeways and enhanced bus services.
Approval by voters in the general election on November 2, 2004 ensured that the half-cent sales tax for transportation would extend for an additional 20 years to 2026 to implement the Regional Transportation Plan.
Some Current Freeway Projects:
Loop 202 Red Mountain Freeway
Loop 202 (Red Mountain Freeway) is complete and open to traffic from State Route 51 east to Power Road. The final segments of the Red Mountain Freeway are under construction, as depicted on the map below.

The SR 802 (Williams Gateway) Freeway corridor would begin in Maricopa County connecting to the Loop 202 (Santan Freeway) near the Williams Gateway Airport at the west end and then heads southeast between the airport and the General Motors proving grounds before heading eastward into Pinal County through the undeveloped Arizona State Trust Lands, to potentially link up with US 60 or SR 79. The SR 802 (Williams Gateway Freeway) study area lies within or adjacent to the jurisdictional boundaries of the cities of Mesa and Apache Junction, the Towns of Queen Creek and Gilbert, and unincorporated portions of Maricopa and Pinal Counties.
State Route (SR) 801 is a proposed east/west freeway in western Maricopa County. It would connect existing SR 85 to the proposed Loop 202 (South Mountain Freeway), with a connection to the proposed Loop 303. This is one of several projects associated with voter approval of the Regional Transportation Plan and is designed to improve traffic flow throughout the Valley.
Loop 303 is an important component of the Regional Transportation Plan – a blueprint for Valleywide transportation improvements through 2025. Plans call for Loop 303 to traverse more than 40 miles of the West Valley – ultimately extending from the proposed State Route 801 (the future I-10 reliever freeway) a few miles south of Interstate 10 in Goodyear to the Interstate 17 (Black Canyon Freeway) near Lone Mountain Road, 2 miles south of the State Route 74 (Carefree Highway).
