The hit-and-run in Oxon Hill closed the I-295 ramp for more than four hours.
The man was outside of his work vehicle behind the lane closure on the ramp from southbound I-295 to the Beltway when he was struck by the car, Maryland State Police said. A witness on the scene called police after 2 a.m.
The 53-year-old Fauquier County, Virginia man was working as a subcontractor for the Maryland Department of Transportation State Highway Administration. Police said it’s unclear why he got out of the work vehicle.
Witnesses believe the man was hit by a black car, which was last seen traveling from southbound I-295 to northbound I-95 on the ramp.
The man was transported to University of Maryland Prince George’s Hospital Center.
The ramp from southbound I-295 at exit 1A reopened around 6:40 a.m.
Maryland State Police are still investigating the hit-and-run and are asking anyone with information to contact them at 301-568-8101.
