US-60/Grand Avenue is an important facility controlled and maintained by the Arizona Department of Transportation (ADOT). It is part of the National Highway System (NHS). Due to its significance to local agencies, it has been the subject of many studies and improvement projects. It serves multiple purposes including local access, commuter travel, and freight movement. It is also a link to Kingman, Arizona and Las Vegas, Nevada.
As the communities along the corridor have developed, the need to reach a consensus on the future for the corridor has never been greater. MAG facilitated the Corridor Optimization, Access Management Plan, and System Study (COMPASS) along the US-60/Grand Avenue corridor. The study area begins at the State Route 303 Loop traffic interchange in Surprise and ends at the Willetta Street intersection in Phoenix. It passes through portions of the Surprise, El Mirage, Youngtown, Peoria, Glendale, Phoenix, and Maricopa County. The corridor is operated and maintained by ADOT.
