A pedestrian who was struck by a vehicle while walking in the right lane of the Sousa Bridge on Friday has died of his injuries, according to D.C. police.

He was identified as Joseph Brown, 61, of Southeast. Police said he died at a hospital on Monday.

The accident occurred Friday about 5:45 a.m. when police said a 2006 Chevrolet truck being driven west across the bridge on Pennsylvania Avenue struck Brown. Police said the driver of the truck remained on the scene and the cause of the accident is under investigation.

The crash followed days of snow and ice in the District that snarled traffic. Additional snow and sleet fell overnight Thursday into Friday. Police would not say if weather was a contributing factor in the accident.
