The Arizona Department of Transportation is continuing improvements to Loop 303 in the northwest valley. Three projects, stretching from US 60 (Grand Avenue) to Happy Valley Parkway will help improve traffic conditions. During construction, closures and restrictions may occur. Drivers are reminded to slowdown and be alert when traveling in the work zones. DPS officers will periodically patrol the area to enforce the reduced speed limit.
Loop 303: Happy Valley Parkway to El Mirage Road
Construction is currently underway to widen the Loop 303 to three lanes in each direction. It is anticipated that this section of roadwork will be complete in summer 2015. As part of this project, two sound walls are being built on the south side of Loop 303. The roadway improvements will be utilizing material from the existing roadway and have a rubberized asphalt paved surface.
