A truck burst into flames on a Massachusetts highway Wednesday, closing all lanes in one direction for part of the evening commute.
The fire on I-495 south, near Exit 20 in Milford, snarled traffic, blocking all three lanes and causing a seven-mile backup during rush hour.
The truck was filled with folders and office supplies. There was not believed to be any hazardous waste.

The driver, a 45-year-old man from Plymouth, said he heard a "bang" in the truck and got out. Then, he said, smoke started billowing out and the vehicle went up in flames.
There were no injuries in the blaze.
After the fire was put out, officials continued working to clean up the roadway.
The southbound side of the highway was closed in the area during the Wednesday evening commute, with police advising people to seek alternate routes. By the time one lane had reopened, traffic had backed up to Hopkinton, seven miles away.
By 6:45 p.m., the fire was out and the truck had been towed away. All lanes had been reopened by 8:30 p.m.
