EAST FLAGSTAFF TRAFFIC INTERCHANGE PROJECT

PROJECT DESCRIPTION

The East Flagstaff TI required an innovative approach to traffic control to accommodate high traffic volumes through an interchange which connects I-40 to the US 89 to Page and the Grand Canyon. Vastco minimized impact to the traveling public, while building a type 6 AASHTO girder bridge over the BNSF Railroad and Route 66.

The reconfiguration of this interchange is the largest TI project contracted in northern Arizona, and will be delivered to ADOT on time and with Value Engineering due to creative traffic control. TI improvements included adding several miles of pedestrian and bicycle trail to the Flagstaff Urban Trail System.
