Advisory: Framingham to Westborough
Closures will occur on Tuesday, May 6, and Thursday, May 8, from 11:59 P.M. to 5:00 A.M. the following morning.
The Massachusetts Department of Transportation (MassDOT) is announcing overnight closures of I-90 westbound between Framingham and Westborough for work related to the I-495/I-90 Interchange Improvement Project.
During the closure, I-90 westbound traffic will:
- Exit at Route 9 westbound (exit 111)
- Follow detour signs to I-495 southbound (exit 58)
- Re-enter I-90 westbound from I-495
Appropriate signage and police details will guide drivers through the detour. Drivers should expect delays, reduce speed, and use caution. All scheduled work is weather-dependent and may be rescheduled in an emergency.

About the Project
The I-495/I-90 Interchange has experienced traffic demands exceeding its capacity for years. On average, this interchange carries hundreds of thousands of vehicles that travel on both I-90 and I-495, with approximately half of all trucking entering eastern Massachusetts. The deficient geometry concentrates movements through the former toll plaza area, queuing onto the interstate mainlines, and crash rates are twice the statewide average.
Through this project, we will improve the movement of people and goods through the area today and into the future. The project will replace the interchange, eliminate the old toll booth area and weaving areas, improve ramp spacing, acceleration, and deceleration lanes, and add an auxiliary lane from I-495 Northbound to Route 9.
New bridges will be constructed on I-495 over I-90, on I-495 and I-90 over the MBTA/CSX/Amtrak lines, on I-495 Northbound over Flanders Road, and Fruit Street.
