Mass Pike Ramps To I-495 Closing For Construction Work: MassDOT

WESTBOROUGH, MA — Drivers who access I-495 southbound from the Mass Pike may run into some detours this week with the closure of some key exit ramps.

On both Monday and Tuesday nights, MassDOT will close the ramps from east and westbound I-90 to the southbound I-495 lanes. The closures will last from 11 p.m. each night until 5 a.m. the next day, with MassDOT estimating the work will be wrapped up by Wednesday morning.

The following detour will be in place during the closures:

• When the I-90 (exit 106) ramp connecting I-90 eastbound and westbound to I-495 southbound is closed, traffic will be directed to follow the detour signs and use I-495 northbound to exit 59B (Route 9 westbound), to reverse direction back to I-495 southbound.  

This week's closures are part of a flurry of construction activity around the interchange that will be ongoing through the summer. The construction project also affects the Fruit Street bridge between Westborough and Hopkinton.
