Milton Road Corridor Master Plan

Study Overview

Milton Rd (aka SR 89A) is the primary roadway corridor within the heart of the City of Flagstaff, yet experiences severe traffic congestion during peak-hour traffic during weekdays as well as gridlock (bumper-to-bumper) traffic during winter weekends due to nearby snow play destinations. The purpose of the Milton Rd Corridor Master Plan is to identify a 20-year vision for the corridor by obtaining public and stakeholder input on alternative improvement strategies.
