Loop 303 is an important component of the Regional Transportation Plan – a blueprint for Valleywide transportation improvements through 2025. The plan was spearheaded by the Maricopa Association of Governments through an extensive public process to identify regional transportation priorities and was approved by voters in November 2004 through Proposition 400. Funding for the plan became effective in January 2006.
The Arizona Department of Transportation (ADOT) is charged with implementing the highway component of the Regional Transportation Plan, which includes $9 billion in new freeways, freeway improvements and maintenance.
Plans call for the Loop 303 freeway 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 Interstate 17 (Black Canyon Freeway) near Lone Mountain Road, 2 miles south of State Route 74 (Carefree Highway) in Phoenix.
Currently, Loop 303 extends for more than 21 miles from Interstate 10 in Goodyear to Happy Valley Parkway in Peoria, operating primarily as a two-lane roadway from I-10 to US 60 (Grand Avenue), and becoming a four-lane divided highway from US 60 to Happy Valley Parkway.
The proposed plan for Loop 303 includes the construction of three general-purpose lanes in each direction between I-10 and I-17 by 2017 – with an interim project to connect the northern section of Loop 303 to I-17 in 2012. Environmental and engineering studies are being finalized to construct the Loop 303 in stages beginning in 2009. These studies are the first step in developing the Loop 303 corridor as a new regional freeway link in the Northwest Valley.
