About this file
This document package includes construction plans and specifications for the Willow Creek Bridge Replacement Project. The project consists of removing an existing timber bridge and installing a new steel superstructure, concrete grade beams, gravel wear surface, rip-rap, and four Type 3 object markers. The plans show design details for the prefabricated modular steel bridge, precast concrete footings and grade beams, approach construction, and erosion control measures. Specifications require the contractor to provide structural design calculations and load ratings, and address excavation, backfill, concrete, reinforcing steel, structural steel, bearings, and other materials. The related federal contract opportunity is solicitation number 1240LT22R0011 issued by the USDA Forest Service Intermountain Region to replace the Willow Creek Bridge on Sawtooth National Forest Road 70227 in accordance with the provided plans.
