A man is dead after a crash on the Clara Barton Parkway on the border between D.C. and Montgomery County, Maryland, early Monday morning.

U.S. Park Police officers responded to reports of a vehicle crashing through a roadside barrier at Little Falls Branch, close to the state line, and tumbling 60 feet down an embankment shortly after midnight Monday.

Murat Siyam, 45, of Rockville, was taken to a hospital for treatment, where he later died of his injuries. He was the sole occupant of the vehicle.

Further investigation revealed that Siyam left the roadway and struck a tree on the west end of the bridge, a spokeswoman for the U.S. Park Police said.

The WTOP Traffic Center reports the Clara Barton Parkway reopened to all traffic around 5:30 a.m. after a five-hour closure for a crash reconstruction and cleanup between the Glenn Echo Turnaround and the Chain Bridge.
