The westbound Bay Bridge has reopened after being closed for about an hour as a result of a crash involving a tractor-trailer and a Corvette.

The crash occurred at 4:52 p.m. when a tractor-trailer ran into the rear of a Corvette, said Sgt. Jonathan Green, spokesman for the Maryland Transportation Authority Police. He said the driver of the  Corvette suffered non-life-threatening injuries but was taken by Medevac helicopter to Maryland  Shock-Trauma Center,

Green said the bridge  was in two-way operations at the time of the crash -- with one of the three lanes being used to help relieve the heavy flow of eastbound traffic for a beach weekend. However, Green said both of the vehicles involved were traveling west  in the right lane.

After the crash, traffic  backed up for miles in both directions and was still moving slowly at 6:25 p.m., traffic cameras showed.
