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 Interstate 10 in Goodyear to Interstate 17 south of Carefree Highway. Most of the current roadway has been upgraded to freeway standards. There is a short non-freeway section from just north of Clearview Boulevard to El Mirage Road that will be updated by 2016. It is currently undergoing construction and has been repainted to a 2 lane road to allow work on the westbound lanes. == Route description == Loop 303 currently begins at a stack interchange with I-10 in Goodyear. 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 the BNSF Railway near Olive Avenue. At an interchange with Greenway Road, Route 303 enters a residential community and turns northeast, becoming a two lane highway past Clearview Boulevard. The route heads over a bridge above Grand Avenue (US 60) (access given by temporary connector road) along with another BNSF railroad line.〔 The route turns eastward and becomes a 4-lane limited-access highway (which will eventually be upgraded to a 6-lane freeway, currently is a 2-lane highway).〔 It then becomes a controlled-access highway at El Mirage Road. 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 will become Sonoran Desert Drive. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arizona State Route 303」の詳細全文を読む スポンサード リンク
