Loop 101 (Agua Freeway), 75th Avenue to I-17 Improvements

Overview

The Arizona Department of Transportation, in cooperation with the cities of Glendale, Phoenix and Peoria, the Federal Highway Administration and the Maricopa Association of Governments, has initiated a project to widen and make other improvements to the Loop 101 (Agua Fria Freeway) between 75th Avenue in Glendale and Interstate 17 in Phoenix. The project seeks to address growing traffic demands in the northwest Valley and relieve traffic congestion on the Loop 101 during the morning and evening peak travel periods. The project will connect with the current Loop 101 Pima Freeway widening project east of I-17, which is slated for completion in early 2022.
