Pickaway County needed to replace an existing narrow pin connected, 102 year old, steel truss bridge. After analyzing the site, it was determined that the best solution was another steel truss bridge designed by U.S. Bridge. Working with county officials, U.S. Bridge began the design process for the replacement. A change in the alignment was going to require a longer bridge. The new structure measures 160’ in length and 32’ in width. U.S. Bridge acted as the General Contractor on this project and was responsible for the removal of the existing bridge and abutments, the installation of the new abutments, the design, fabrication and erection of the new structure, the placement of the new concrete deck and the fabrication and installation of the new twin tube independent rail system. Designed with an HS20 load rating, this bridge will accommodate all vehicular and pedestrian traffic including all maintenance and emergency vehicles, for generations to come. U.S. Bridge designed the bridge with a double bottom chord. This feature eliminates the possibility for the collection of water and debris which can lead to the accelerated deterioration of the steel thereby compromising the useful life of the structure. Further, the U.S. Bridge bottom chord tension member design and the two independent channel members permit the structure to be deemed “redundant”. AASHTO Bridge Design Manual states that to qualify for a “redundant” designation, the load path structures must have a multi-load paths where a single fracture in a member cannot lead to a failure of the entire structure. Recognized by the American Institute of Steel Construction, U.S. Bridge is certified for the manufacture of both major and simple steel bridges with a both a “Fracture Critical and Sophisticated Paint Endorsement “. U.S. Bridge, founded in 1936, is the nation’s largest producer of prefabricated steel vehicular truss and steel beam bridges. Complementing the vehicular bridge product line is a variety of custom designed and engineered pedestrian bridges.
