HOPKINTON – It’s a big week in the I-495/Mass Pike interchange project, with the new I-90 westbound ramp to I-495 northbound scheduled to open this week, weather permitting.
Before that happens, there will be more overnight closures. From tonight through Thursday, the I-495 northbound ramp to Route 9 East will be closed from 10 PM to 5 AM each night. The detour will send drivers onto Route 9 West to turn around.
Those closures are in addition to overnight work within the I-495/I-90 interchange itself.
