UPDATE: 3:08 p.m. A motorcycle accident on the northbound side of the American Legion Bridge is causing delays this afternoon.
The Maryland State Highway Administration says all lanes will be closed in each direction so a Medevac helicopter can land and pick up the victim. All lanes of the outer loop will open after the helicopter leaves.
One lane of traffic on the inner loop right hand shoulder was getting by as Fairfax and Montgomery County rescue officials respond.
