Northwest Phase II

Northwest Phase II


Valley Metro is currently preparing the federally-required Environmental Assessment (EA), which evaluates the potential impacts to the neighboring environment including noise, vibration, traffic, historic properties and cultural and archaeological resources. With preliminary engineering (15% design) complete, competitive procurements for the designer, contractor and project artists are underway.

Next Steps

The EA will be complete in late summer 2017. Community outreach is ongoing, and the public will have an opportunity to provide comments on the EA before it is final. Final design is anticipated to begin this fall.


In 2004, the Phoenix City Council approved the Northwest Light Rail Extension, which included 4.6 miles of additional light rail service, extending from the previous end-of-line at 19th Ave. and Montebello Ave. to 25th Ave. and Mountain View Rd. In 2007, the route was divided into two phases. The 3.2-mile Phase I on 19th Ave. from Montebello to Dunlap Ave. opened on March 19, 2016.

Phase II of the project will extend west on Dunlap Ave., north on 25th Ave. and across I-17 near Mountain View Rd. with a terminus on the west side of the freeway near Metrocenter Mall. The Phoenix City Council approved the I-17 crossing in 2014.

In January 2016, the Phoenix City Council approved accelerating segments of the future high-capacity/light rail transit system. With the acceleration, Northwest Phase II will open in 2023, three years earlier than previously planned.
