History of the Northern Parkway Project

Program Development

Inception to Implementation

The Northern Parkway Program concept was initially conceived by a multi-agency transportation task force consisting of representatives of El Mirage, Glendale, Peoria, Maricopa County Department of Transportation (MCDOT), the Flood Control District of Maricopa County (FCDMC), the Arizona Department of Transportation (ADOT), Maricopa County Association of Governments (MAG) and Luke Air Force Base (LAFB). It was further developed in the Northern Parkway Design Concept Report (October 2003).

In November 2003, MAG adopted the Northern Parkway concept recommended in the 2003 Design Concept Report, and included the parkway in its Regional Transportation Plan (RTP). The following year, the parkway was adopted by Maricopa County and included in MCDOT’s Major Streets and Routes Plan. Proposition 400, the extension of the countywide half-cent sales tax, was passed by voters in November 2004 and provided the regional funding source for the design and construction of the future Northern Parkway.

A Draft Design Concept Report (DCR) and the Draft Environmental Assessment (EA) were prepared respectively in July 2008 and September 2009. The Final DCR was completed in April 2010 and the Final EA was approved in May 2010. The Federal Highway Administration (FHWA) issued, a Finding of No Significant Impact (FONSI) for the project in May 2010.

Pursuant to the intergovernmental agreement approved by the Northern Parkway Program partner agencies in December 2008, MCDOT is leading final design efforts and is managing construction of the Northern Parkway between Loop 303 and US 60 (Grand Avenue).
