Arizona State Route 303

Arizona State Route 303, also known as Loop 303 (spoken as three-oh-three) 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. As of 2004 it was renamed "Bob Stump Memorial Parkway" to honor former Arizona congressman Bob Stump.

Its route runs from West Van Buren Street in Goodyear to Interstate 17 south of Carefree Highway. As of Fall 2017, Loop 303 is a full freeway from just south of I-10 to I-17.

Route description

Loop 303 currently begins at Van Buren Street , south of I-10 in Goodyear and at I-10 becomes a six-lane freeway with a stack interchange. South of Van Buren Street it continues as Cotton Lane but without a route number. It heads north under McDowell and Thomas Roads, then over an interchange with Indian School Road. The road heads through a farmland terrain and passes the Wildlife World Zoo near Northern Avenue. It over passes a BNSF Railway spur line near Olive Avenue. At an interchange with Greenway Road, Route 303 enters a residential community and turns northeast. The route heads over a bridge above Grand Avenue (US 60) along with another BNSF railroad line. The route turns eastward and was recently upgraded to a six-lane freeway. It turns north near the Happy Valley Parkway interchange and then east again south of Lake Pleasant, passing through planned arterial interchanges. The freeway comes to an end at a temporary at-grade interchange (eventually to be a stack interchange with I-17 near Skunk Creek. East of this interchange, Route 303 becomes Sonoran Desert Drive. The south end from US 60 to I-10 is frequently used to bypass Grand Avenue and quickly move from Grand Avenue to Bell Road.

History

Loop 303 was originally a part of the 1985 Maricopa County Regional Transportation Plan that was funded by a sales tax approved by Maricopa County voters. The freeway, designed to service the Northwest Valley, was originally designated SR 517 in 1985; the Loop 303 designation was first assigned on December 18, 1987. The freeway was scheduled to be completed sometime by 2005. However, funding shortfalls and increasing construction costs forced cutbacks in the plan, and in 1995 the freeway was dropped from the regional plans.

Maricopa County took charge of what was then called the Estrella Freeway project when it was dropped from the regional freeway plans, maintaining it as an interim 2-lane highway along the original corridor while keeping the state route designation. The county then made significant improvements to the roadway, extending it several miles north and east of US 60. While the highway was still largely a 2-lane rural road, the extension north of US 60 along with the southern terminus just north of Interstate 10 was upgraded to a 4-lane divided parkway, and the segment between US 60 and Bell Road in Surprise was partially upgraded to controlled-highway standards with overpasses and right-of-way for on-ramps.

With the extension of the sales tax approved in 2004, the highway was once again added to the Regional Transportation Plan. As Maricopa County had completed much of the required study and preparation work, construction on the freeway proceeded with a planned completion date of the I-10 to I-17 segment by 2015. According to an agreement between the state legislature and the state department of transportation, STAN (Statewide Transportation Acceleration Needs) funds were used to build a partial interchange at Bell Road in summer 2010, several years before previously intended. In mid-2011 the segment between Happy Valley Parkway and I-17 was completed as a four-lane highway with an interchange at Lone Mountain Parkway completed but initially closed to the public. Motorists still have to pass through signaled ramp junctions at the I-17 Black Canyon Freeway until a full stack interchange is built between that route and Loop 303.

Future

Long-term plans call for the extension of Loop 303 south of the interchange with I-10 in Goodyear to the planned I-10 'Reliever Route' Freeway, SR 30, and continuing south through Goodyear to connect with the planned alignment of future Interstate 11. Loop 303 would run concurrent with I-11 for several miles, before splitting off southward towards its ultimate terminus at Interstate 8 west of Casa Grande. If completed, Loop 303 will serve as a Phoenix bypass route for the southwestern suburbs of Goodyear, Avondale, and Buckeye as well as an alternate Phoenix bypass route for I-10 traffic headed westbound to the Greater Los Angeles Area and northbound via I-17 to Flagstaff.

In response to a projected budget shortfall of $6.6 billion brought on by the recession, the Maricopa Association of Governments voted to suspend funding to numerous projects during a meeting on October 28, 2009. Some modifications to Route 303, such as a scaled-back design of its interchanges with I-10 and US Highway 60, were made to cope with the budget shortfall. Funding for the extension south of I-10 to the planned alignment of SR 30 was removed, effectively postponing the extension until after 2025.
