Reconstruction of Canaan Southfield Bridge

BSC Group balanced rapid construction techniques and structural/highway engineering services for the reconstruction of Canaan Southfield Road Bridge over the Umpachene River in New Marlborough, MA. BSC worked with the Town’s accelerated schedule and in just ten weeks completed the design and bid package, along with the submission of the necessary environmental permits. BSC designed new retaining walls, bridge superstructure, and traffic safety controls and also tested, evaluated, modified, and reconstructed the existing substructure for reuse and to meet current MassDOT and AASHTO LRFD standards.

Additionally, the roadway profile was raised slightly to accommodate the increased bridge elevation and eliminate drainage issues. To correct and prevent future riverbed erosion, the existing abutments were armored with protective riprap and the existing scour pockets were filled.
