Harford County sheriff's deputies are looking for the people who threw a large piece of concrete from the Vale Road Bridge and struck a car traveling on the U.S. 1 bypass in the Bel Air area, authorities said.
The concrete damaged a 2004 Mazda 6 driver-side door and mirror at 12:45 a.m. yesterday, said Harford County Sheriff's Office spokesman Sgt. David Betz. The driver, who pulled off to the side of the road after the impact, and a passenger were not injured, Betz said.
The perpetrators had to heave the rock over the fence of the bridge, Betz said.
