Premier was selected by the Maricopa County Department of Transportation (MCDOT) to provide the final design services for El Mirage Road from Northern Avenue to Cactus Road. During scoping negotiations, the final design for these roadway improvements was broken into two concurrent project phases: Northern Avenue to Olive Avenue – Phase I and Olive Avenue to Cactus Road – Phase II. This project also included intersection improvements at Olive and Peoria Avenues and Cactus Road.
The roadway improvements included widening the existing El Mirage Road to three lanes in each direction with a raised median extending from approximately 1,400-feet north of Northern Avenue to Heritage Park (Cinnabar) on the west side of El Mirage Road just south of Peoria Avenue. The roadway tapers to two lanes in each direction with a raised median from Heritage Park to Peoria Avenue continuing with a paved median from Peoria Avenue to Cactus Road.
