A truck fire on Route 146 closed part of the highway in Massachusetts Monday morning.
State police said one lane was open at 6:30 a.m. The trailer truck caught fire on 146 north, near the Uxbridge and Douglas town line just before 2 a.m.
Both northbound lanes had to be closed, and traffic was diverted off Route 146.
At one point, the fire created a 3/4 mile traffic backup.
