• Abstract:
  The report documents an economic design study to determine the best alternatives for rapid and economical replacement of bridges in rural locations. Two lane simple span bridges with spans up 100 feet were considered. A steel bridge using rolled W sections with either metal grid deck or a composite cast in place concrete deck was found to provide an economical solution. If speed on construction was important, the metal grid deck provides significant construction time savings. The cast in place concrete deck reduces the bridge cost but may double or triple construction time. The study included evaluation of prestressed concrete girders, double T beams, and solid slab bridges. The prestressed girder with a cast in place slab provides the most economical solutions for longer spans. For shorter spans, less than 60 feet, the rolled beam steel bridge was the most economical. The concrete bridges require larger cranes for erection and trucks for transportation which makes them less suitable for rural bridges built by small local contractors. Details of the steel girder bridge design are included including a novel cross frame design and a detailed LRFD example.
