US 180 Corridor Master Plan


US 180 (aka Humphreys St or Fort Valley Rd) is the primary roadway corridor to the Arizona Snowbowl and experiences gridlock (bumper-to-bumper) traffic during winter weekends due to nearby snow play destinations. The purpose of the US 180 Corridor Master Plan is to identify a 20-year vision for the corridor by obtaining public and stakeholder input on alternative improvement strategies.
