Update at 6:25 p.m. — All lanes have reopened.
The northbound (inbound) lanes of the Key Bridge are closed due to a “police situation.”
Initial reports suggest a person may have jumped off the bridge, possibly on the D.C. side. Traffic cameras show Arlington police redirecting traffic heading toward the bridge on N. Lynn Street onto northbound Lee Highway and the George Washington Parkway.
Traffic appears to be flowing from the District into Arlington across the Key Bridge.
Very heavy traffic has been reported in Rosslyn and across the bridge in Georgetown.
