A major construction project on the Mass Pike near Boston could have drivers sitting in traffic for hours this weekend. Starting Friday night and lasting through early Monday morning, work to replace a highway bridge will require lane closures in both directions.

Weekend lane closures on I-90 at the I-95 interchange in Newton and Weston could cause 2-3 hour delays as MassDOT begins a multi-year bridge rehabilitation project.

Weekend lane closures and rolling roadblocks may result in "two-to three-hour delays" for drivers at the Interstate 95/Massachusetts Turnpike interchange as a multiyear bridge rehabilitation project moves forward.
