Winter Street Bridge Over I-95 Reconstruction

Winter Street Bridge Over I-95 Reconstruction

Waltham, MA

In this major bridge reconstruction Project for MassDOT, McCourt Construction reconstructed the Winter Street Bridge over Route 128 / Interstate 95 and the interchanges on either side. The project involved building a temporary Bridge over the highway (including temporary drilled shafts and piers), and realigning the roadway to take traffic off the old bridge. McCourt then demolished the existing bridge. Next the new bridge was constructed including drilled shafts and new piers and abutments. Finally the interchanges on either sides of the bridge were reconstructed to improve the traffic flow of the on and off ramps.

Also included in the project was building several cast-in-place and natural stone retaining walls, significant traffic control, new and redesigned traffic signals, landscape beautification, and pedestrian improvements. McCourt was able to significantly reduce the schedule by designing a new staging and traffic management plan, which elminated an entire construction stage.
