Northern Parkway is a limited-access road in Maricopa County, Arizona that serves the west part of the Phoenix metropolitan area.

East of El Mirage Road, Northern Parkway crosses the Agua Fria River where it temporarily ends.

In 2003, the Northern Parkway concept was included in Maricopa Association of Governments (MAG) regional transportation plan (RTP).

A year later, residents of Maricopa County voted to extend the regional half-cent sales tax for transportation.

As part of this initiative, a number of major arterial road projects were funded including Northern Parkway.

[5] In 2008, Maricopa County along with the cities of Glendale, El Mirage, and Peoria approved a design concept report for the project.

[8][2] The segment between 99th and 91st Avenues will be taken over by the Arizona Department of Transportation (ADOT), as Northern Parkway intersects Loop 101.

Northern Parkway will be an access-controlled freeway for the six-mile segment from Loop 303 through the Agua Fria River.
