A Baltimore police officer was rushed to Maryland Shock Trauma Center this morning after she was struck by a car on Interstate 83, was thrown off the highway and slid 30 feet down an embankment, according to a city police spokesman.

The highway northbound has been shut down from Falls Road to Northern Parkway. Two lanes of southbound I-83 are open, police said. Baltimore Police warned drivers via Twitter to expect delays due to the crash.

Police spokesman Anthony Guglielmi said the female officer was standing near a vehicle that was to be towed. He said the driver of a car lost control, hit her police cruiser, and the cruiser hit the officer. She suffered multiple leg fractures, among other injuries, Guglielmi said. He said she was conscious when she left in the ambulance.

Baltimore Police Commissioner Frederick H. Bealefeld III was at Shock Trauma this morning.
