ABSTRACT:
A system and method for construction of bridges and elevated roadways with pre-stressed concrete or steel bridge girders is provided including cast-in-place concrete deck slabs and partial and full depth pre-stressed pre-cast concrete deck slabs with post-tensioning conduits for post-tensioning a series of deck slabs. A plurality of bogies traveling on the lower flanges of the bridge girders are provided to place and level the deck slabs and to pre-load the bridge girders to eliminate camber before placement of the deck slabs on the bridge girders or to level, place, support and remove deck forms for a cast-in-place deck slab on the bridge girders. Also provided is a system for attachment of cast-in-place parapets.
