Advisory: Hopkinton, Westborough
I-495 Northbound Lane Closure Began Saturday, August 15
What is Happening?
The Massachusetts Department of Transportation (MassDOT) is announcing a right lane closure on I-495 northbound at the I-495/I-90 interchange to facilitate construction operations.
I-495 Northbound Lane Closure
The right lane closure on I-495 northbound, which began on Saturday, August 15 will remain in place for approximately three weeks. This traffic management change is required in preparation for upcoming construction staging for the I-495/I-90 Interchange Improvements Project. The right lane will remain open until the ramp to I-90 westbound and eastbound (Exit 58). Traffic traveling on I-495 north of the I-495/I-90 interchange should utilize the two left lanes.
As a reminder, there will be overnight ramp closures the I-495/I-90 interchange this week. See the traffic and construction updates page on the project website for details on which ramps are closed which nights, as well as detour routes.
Appropriate signage, law enforcement details, and messaging will be in place to guide drivers through the work area.
Drivers traveling through the affected areas should expect delays, reduce speed, and use caution.
All scheduled work is weather dependent and/or may be impacted due to an emergency.
About the Project
The purpose of the I-495/I-90 Interchange Improvements Project is to provide a safe and efficient interchange of the interstate highways I-495 & I-90. 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 on Fruit Street.
