The Inner Loop of the Capital Beltway was backed up for four miles before evening rush hour Thursday because of a crash, officials said.
A crash on the Inner Loop of I-495 at Rockville Pike (MD 355/Exit 34) initially shut down a section of the Beltway in Maryland, the Maryland State Highway Administration said.
