BOSTON (WHDH) -- An over-height truck struck the ceiling of the Sumner Tunnel at 11:15 a.m. Tuesday.

State Police say the massive tractor trailer struck the ceiling of one of the exit tunnels coming out of the Sumner Tunnel.

State inspectors say there was no damage to the tunnel, but a lane had to be closed down while air was let out of the tires so the truck could be lowered and moved out.

There was another tunnel mishap last week when a large truck struck a lane signal under the ceiling of the Tip O'Neil tunnel; traffic was backed up while crews made repairs.

Officials say truckers should know their vehicles are too high.

“We do have an oversize alert both on the north and southbound sides of the Tip O’Neill Tunnel. We believe that was activated so the trucker should have known not withstanding all the signage we have up about what the height restrictions are,” said Richard Davey, Mass. Transportation Secretary.

Other truckers agreed, but were not quite as diplomatic.

“Yeah, pretty much stupidity,” a trucker said.

The signs are quite visible. Signs say 13 feet, 9 inches clearance going into the Tip O’Neil Tunnel, and 12 feet, 6 inches going into the Sumner Tunnel.

“I think that they’re not paying attention to where they’re going. It’s well marked, the heights are. And if you’re paying attention you wouldn’t go into the low tunnel,” a truck driver said. “I’ve never hit a bridge and I’ve never hit a tunnel in 32 years.”

State police have towed the truck that hit the Sumner Tunnel ceiling and intend to inspect it.
