About this file
This is a Bridge Summary Report documenting the condition and characteristics of a county highway bridge in Arizona. The bridge, identified as Structure Number 8250, carries Tower Mountain Road over a wash approximately 26.35 miles west of Interstate 17 in Yavapai County's Northwest district. Built in 1955 and maintained by the County Highway Agency, the bridge consists of two concrete continuous slab spans with a total length of 44 feet and a maximum span length of 21 feet. The structure accommodates one lane of traffic with an inventory route minimum vertical clearance of 15.9 feet and a bridge roadway width of 14.1 feet curb-to-curb.
The most recent inspection was conducted in September 2011 with a designated inspection frequency of 24 months. The bridge currently carries an average daily traffic of 150 vehicles (5 percent trucks) and is projected to experience 160 vehicles daily by 2030. While the deck, superstructure, and channel protection conditions are rated satisfactory, the deck geometry appraisal of 2 indicates an intolerable condition requiring high-priority replacement. Multiple safety features—including bridge railings, transitions, approach guardrails, and guardrail ends—do not meet currently acceptable standards. The structural evaluation appraisal is rated 6 (equal to present minimum criteria), and the bridge maintains an operating and inventory rating of 35.7 US tons with posting equal to or above legal loads. The overall bridge condition is classified as Fair (F).
