SR89 / SR89A PRESCOTT-FLAGSTAFF HWY

PROJECT DESCRIPTION

The State Route 89/State Route 89A Traffic Interchange project consists of two bridges which span SR 89 and connect SR 89A with Pioneer Parkway north of Prescott, Arizona. These post-tension concrete structures were built using falsework over SR 89, at a minimal impact to motorists. The bridges are complimented by concrete, aesthetic “sound walls” which reduce roadway noise for area residents. The SR 89/SR 89A TI project involved creative traffic control and was delivered on time and within budget.
