The problem was first detected when a car received a flat tire after driving over the expansion joint at about 6:45 a.m., state police told Boston.com. There were no injuries as a result of that incident, state police said.
One lane remains closed in the area between exits 28 and 29 on I-93 northbound.
A MassDOT spokeswoman told Boston.com that crews are on the scene, and that there is no timetable yet for the duration of the repair work.
