Project Details: WY FLAP JOH 14(1) North Fork Crazy Woman Creek Bridge The Central Federal Lands Highway Division (CFLHD) of the Federal Highway Administration (FHWA), in cooperation with the U.S. Forest Service (USFS) and Johnson County, Wyoming, is proposing to replace the existing bridge structure on Crazy Woman Canyon Road/Route 33. The project road is classified as a rural recreational local road and is in mountainous terrain. The project scope includes the replacement of North Fork Crazy Woman Creek Bridge on Crazy Woman Canyon Road/Route 33, reconstruction of the roadway approaches on both ends of the bridge, object markers installed on the four corners of the bridge, and pullout improvements. The project consists of replacing an existing bridge structure on Route 33/Crazy Woman Canyon Road. The roadway portion will consist of aggregate surface course approaches required for raising the existing profile as well as reconditioning of a pull-off area near the bridge. The existing bridge removal will include existing superstructure and partial demolition of concrete caps (enough to allow new girder clearance). The proposed structure is a 14 feet wide and 51 feet long (out-out abutment) single span structure, leaving existing concrete/grouted riprap embankments in place and building new concrete caps directly behind existing caps after squaring off existing skew. The prefabricated bridge consists of rolled girders and structural steel decking with gravel deck surface similar to the approaches. New abutments are cast-in-place concrete caps and wingwalls supported by micropile foundations, no additional scour protection is assumed to be required with existing rock grouted embankments. A temporary bridge or diversion is not required; however, the existing bridge to be replaced is load rated: 2-3 Axles: 11T 4-5 Axles: 12T 6+ Axles: 13T Semi-Truck: 20T Tandem: 21T Route 33/ Crazy Woman Canyon Road is geometrically tight west of the bridge location, it is not considered feasible to enter the project site from US-16. This work consists of furnishing all engineering services, materials, equipment, and labor required to construct a fully engineered, simple span, one-lane, portable, modular steel girder vehicular bridge with structural steel bridge decking and steel bridge traffic railings for the replacement of the North Fork Crazy Woman Creek Bridge. It includes designing, fabricating, transporting, and erecting the superstructure including steel girders and diaphragms, structural steel decking, steel bridge railings, elastomeric bearing pads, bearing plates, anchor bolts, side dam plates and end angles for aggregate base fill, and all associated hardware. Design and construct the bridge in accordance with these specifications and the plans PRICE: The price range of the project work is between $700,000 and $2,000,000. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. The contract completion date is September 26th, 2025.
