HAVERHILL — The Massachusetts Department of Transportation (MassDOT) has announced that crews will implement daytime lane closures as well as varying overnight lane closures and rolling roadblocks on Interstate-495 north and southbound in Haverhill. The closures began Tuesday, May 28, and will run through Thursday, May 30.

These impacts are necessary to allow crews and contractors to safely and effectively carry out construction work related to the ongoing project to replace the bridge that carries I-495 over the Merrimack River, MassDOT officials said.

The overnight lane closures will take place on I-495 north and southbound each evening between 8 p.m., and 5 a.m., with short term rolling roadblocks implemented by law enforcement intermittently between 10 p.m. and 5 a.m. The daytime lane closures will then take place on I-495 northbound between Exit 48 and Exit 49, from 6 a.m. through 1 p.m.

Signs, traffic control devices and law enforcement officers will be deployed to guide drivers through the work zones. All work is weather dependent and subject to change without notice.
