RESOURCE Grand Avenue Northwest Corridor Study Final Report The Grand Avenue Northwest Corridor Study encompasses an 11.5- mile segment on US 60 (Grand Avenue) between SR 303L and SR 101L. This roadway passes through the cities of Surprise and Peoria, towns of El Mirage and Youngtown, and the unincorporated communities of Sun City West and Sun City. This roadway is one of the primary urban arterials serving these communities and is also a vital link in the statewide highway system. This portion of US 60 serves primarily as the continuation of US 93, which links the Phoenix metropolitan area to Las Vegas, Nevada, and I-15. US 93 terminates in Wickenburg approximately 20 miles northwest of the study corridor. Download (7.1 MB)(PDF)
