The $23 million project to reconstruct and expand the Route 128/I-95 Exit 27A-B interchange with Winter Street/Totten Pond Road in Waltham enters a new phase with a new exit ramp traffic pattern beginning Monday, October 24.
The new Winter Street Bridge, left, reopened to traffic in August. A temporary bridge has been removed and final construction is underway on the connections between the northbound on and off ramps and the new collector road along Route 128/I-95 NB. This new collector road will reduce the conflict points where traffic enters and exits Route 128/I-95 NB.
The overall project is expected to be substantially completed and fully opened to traffic in mid November. The traffic pattern changes are below:
Beginning on Monday, October 24th at 5:00 AM, a new traffic pattern will be implemented for drivers travelling on Route 128/I-95 North seeking access to areas served by Exit 27A (Totten Pond Road) and Exit 27B (Wyman Street/Winter Street). A new collector roadway located parallel to Route 128/I-95 North will be opened to traffic.
At the beginning of the collector roadway, a single exit point located south of Winter Street will be available for drivers travelling on Route 128/I-95 North destined to Exit 27A or 27B. At the end of the roadway, a single entry point located north of Winter Street will be available for drivers accessing Route 128/I-95 North.
MassDOT encourages drivers on Route 128/I-95 North to check portable changeable message signs and follow directional guide signs to access Exits 27A–B.
