Fairfax County police responded to a car which crashed into a transmission pole at the intersection of Telegraph and Hayfield roads, near the Hayfield Plaza Shopping Center, around 9:30 p.m. Monday.
One person was transported to a hospital with injuries considered life-threatening. A second person also transported is expected to recover.
The route is one some people take to get to Fort Belvoir.
The WTOP Traffic Center reports Telegraph Road reopened to all traffic around 6 a.m. after an extended closure for a crash investigation. Dominion Energy was also present Tuesday morning assessing damage to the pole.
