A spur of Interstate 895 in Anne Arundel County that leads to the Harbor Tunnel Throughway was closed Thursday night because of a six-vehicle accident.

The accident, which occured about 6 p.m., left a dump truck blocking the two northbound traffic lanes, said Sgt. Kirk Perez, a spokesman for the Maryland Transportation Authority Police.

As of 7:15 p.m., officers were still waiting for heavy equiptment to move the truck from the roadway, he said.

Four people were hurt during the crash but none of the injuries are life-threatening, Perez said.

The injured were taken to Maryland Shock Trauma Center for treatement, he said.

The blocked spur connects Interstate 97, the Baltimore Beltway and Maryland Route 2 -- Ritchie Highway -- to the Harbor Tunnel Thruway.

Motorists are being detoured onto the beltway, Interstate 695, to get to the tunnel.

No major delays were reported on public transit Thursday evening.
