Reconstruction of Route 1 and Route 1A Bridges over I-95
Dedham/Westwood, MA
This project, part of MassDOT’s Route 128 “Add-a-Lane” series of projects to widen Interstate 95 from Braintree to Needham, includes the replacement of the heavily traveled Route 1 and Route 1A bridges over Interstate 95, including both shoulder and median widening of I-95 to accommodate an additional lane of travel. In addition to the bridge work, SPS is self-performing construction of four noise walls totaling over 6,000 linear feet. Other improvements include the installation of overhead signs, drainage, detention basins, water quality swales and new pavement on over five lane-miles of interstate.
