Orginal post: An accident at Route 1 and the Fairfax County Parkway may tie up traffic in the area, which is already congested with rush-hour traffic, for several hours, according to emergency officials.

Authorities say police and rescue crews are on the scene, and drivers should seek alternate routes.

However, the lack of major surface roads in the area is going to make that difficult, especially if you’re already on the road.
