Arizona State Route 303 (SR 303) or Loop 303, also known as the Bob Stump Memorial Parkway (formerly the Estrella Freeway), is a freeway that serves the west part of the Phoenix metropolitan area. The freeway, originally a two-lane rural highway, was maintained by Maricopa County until 2004 after approved sales tax when the Arizona Department of Transportation again took control of upgrading the interim road to a freeway.[citation needed]
