Traffic on Interstate 895 north was delayed Wednesday afternoon after four vehicles collided about one mile south of the Harbor Tunnel, according to the Baltimore City Fire Department.
Rescue personnel responded to the scene about 12:42 p.m. to find two pickup trucks and two cars heavily damaged in the roadway from a collision, said Chief Kevin Cartwright, a fire department spokesman.
Two people in one of the cars were transported to Maryland Shock Trauma Center after being extricated from the car by rescue personnel, Cartwright said. Neither was in critical condition, Cartwright said.
A third person was treated at the scene but refused further medical treatment and transportation to a hospital, he said.
Traffic was expected to be delayed for more than an hour because of "extensive damage to vehicles and debris on the roadway," Cartwright said.
Maryland Transportation Authority Police are investigating the cause of the collision.
