Bridge and track construction

BNSF new Bridge construction near Columbus, NE with Record Precast Spans

We provided record length pre-cast concrete spans of 125' over the Platte River near Columbus, Nebraska. The concrete girders were cast in two pieces and trucked to the job site assembly yard. At the assembly yard the two halves were spliced together with post-tensioning steel and high strength  epoxy. Then the girders were transported from the assembly yard out to the bridge piers with two crawler cranes then out on the man made causeway and erected. Intermediate diaphragms were then erected  and the girders were post-tensioned together transversely with high strength steel rods.
