Northern Parkway

Project Overview

The Northern Parkway Corridor projects are the result of a partnership with many local agencies and jurisdictions including the Arizona Department of Transportation (ADOT), Maricopa Association of Governments (MAG), Maricopa County Department of Transportation (MCDOT), City of El Mirage, City of Glendale, and City of Peoria. The corridor projects extends 12.5 miles between Loop 303 and US 60 (Grand Avenue) in northwestern Maricopa County. MCDOT is leading final design and construction efforts. The project development will be done in several different phases which can be seen throughout this page.

Cost & Funding

The majority of funding for the Northern Parkway (70%) will come from regional sources, primarily Federal Surface Transportation Program funds (STP), allocated via the Maricopa Association of Governments (MAG) to Maricopa County. The remaining 30% will be from the partners.

Pursuant to the IGA, $315.8 million is budgeted for the Northern Parkway based on the MAG Regional Transportation Plan. This represents roughly half of the total projected cost of $612.6 million.
