B & H Engineering has provided construction support services to the New York City Department of Transportation for the demolition of the East 156th Street Bridge. The project involved the dismantling and disposal of the existing bridge spanning the railroad tracks owned by the National Railroad Corporation. The bridge was comprised of three spans. The first and second spans were through trusses crossing over the railroad tracks. The third span, a girder span, crossed an unpaved road.

The construction support services included the following: the review of the contractor's demolition procedure, abutment reinforcement, contractor's proposed loading, protective shielding, temporary sheet piling design, and temporary structures. The project involves removal of the superstructure, and the piers to the top of the footings. The top portion of the abutments will be removed and reconstructed with new parapet walls and fences at street level. The approaches will be reconstructed and new turf placed where the street leads into the bridge.
