This project, part of MassDOT’s Route 128 “Add-a-Lane” series of projects to widen Interstate 95 from Braintree to Needham, includes replacement of the heavily-traveled Rte. 1 and Rte. 1A bridges over I-95, including both shoulder and median widening of I-95 to accommodate an additional travel lane.
In addition to the bridge work, SPS self-performed 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
