7:40 p.m. Update: Massachusetts Avenue has reopened to traffic.
6 p.m. Update: District transportation officials say the truck, trailer and a backhoe have been removed from the tunnel. Cleanup is underway. The backhoe apparently became wedged against the ceiling, they said.
4:45 p.m. Update: The truck is still blocking the tunnel. However, delays persist in both directions. Transportation officials recommend that drivers use alternate routes. Possibilities include New York and Rhode Island avenues.
Original post: A dump truck towing construction equipment on a trailer is stuck in the eastbound Massachusetts Avenue tunnel that runs beneath Thomas Circle, according to D.C. Fire/ EMS spokesman Pete Piringer.
However, Piringer said there was hydraulic fuel spilled at the scene, so a team will have to be dispatched to do cleanup. Expect significant delays in the area due to the accident.
There is heavy damage to the vehicle but no injuries, Piringer said.
