This project consisted of the removal and replacement of the superstructure and the partial removal and modification to the abutments of the Northern Indiana Commuter Transportation District (NICTD) Bridge over Hobart Road (Bridge 54.62) in Gary, Indiana. The scope of work included the removal of the existing steel through plate girder superstructure, partial removal of the abutments including the abutment seats and backwall, installation of a new steel through plate girder superstructure, construction of new concrete abutment seats and backwalls, and installation of sheet piling at the four bridge approach corners. The final placement of the superstructure was based upon the use of temporary roll-in bents for the erection and rapid insertion of the new superstructure onto the modified substructure.
