The Old Bass River Road Bridge above Route 6 in Dennis was closed to traffic Friday evening after a crane being transported by a truck struck the bridge and caused serious injury to a person in a passing vehicle, officials said.
The impact caused debris to dislodge from the bridge and crash through the window of a passing vehicle, causing injuries to a person inside that were serious but not believed to be life-threatening, State Police spokesman David Procopio said in an e-mail.
Firefighters had to use the Jaws of Life to remove an injured person, Procopio said.
The truck carrying the crane was traveling westbound when it hit the bridge from beneath at around 6 p.m., according to a statement from the Massachusetts Department of Transportation.

Two of the bridge’s beams were severed in the incident and there may be additional damage, according to the statement. Bridge inspection crews were on site to evaluate the bridge structure, and engineers will determine what repairs are necessary.
The eastbound lanes and one westbound lane reopened Friday night, but the road above the bridge remained closed as of about 11:30 p.m., Procopio said. The cause of the crash is under investigation, Procopio said.
