The Arizona Department of Transportation (ADOT), in conjunction with its local municipal partners and the Federal Highway Administration, has initiated a Grand Avenue Feasibility Study to identify, evaluate and recommend improvement projects along Grand Avenue between Loop 303 and Loop 101.

This study will identify, evaluate and prioritize improvements along this segment of Grand Avenue for implementation in Phase II (2011-2015) of the voter-approved Regional Transportation Plan (RTP) for Maricopa County, with an emphasis on projects that would improve capacity and traffic flow. The RTP provides $64 million in funding for “unspecified” improvements to Grand Avenue from Loop 303 to Loop 101 that are consistent with regional planning studies, including recommendations in the Grand Avenue Northwest Corridor Study, SR 303L to SR 101L (January 2003) and the Grand Avenue Major Investment Study Phase II Final Report (February 2006).

Projects being considered in the study would be in addition to the planned widening projects from Loop 303 to 99th Avenue, which are included in Phase I (2006-2010) of the RTP.

Several criteria, including public input, construction feasibility, engineering and cost factors and environmental and right-of-way impacts, will be used to prioritize projects in the study.

ADOT expects to prepare a draft recommendation on preferred projects and hold public open houses in spring 2008 to obtain public input on the study recommendations. The final study report is expected to be published in summer 2008. The study recommendations will then be submitted to the Maricopa Association of Governments to be evaluated for implementation in the RTP through the established MAG process.
