Drivers should expect lane closures on the Whitehurst Freeway over the next two months, as the D.C. Department of Transportation continues its work on the Francis Scott Key Memorial Bridge.

DDOT said it will close a lane eastbound and then westbound on the Freeway during the day until March 30. The closures will likely take place between 9:30 a.m. and 3:30 p.m. to avoid impacting the heaviest rush hour.

The lane closures come as the result of DDOT’s work to rehab the Key Bridge spanning the Whitehurst Freeway. It will be installing scaffolding and conducting inspections during this time. To avoid the Whitehurst Freeway, drivers can take M Street instead.

The Key Bridge, built in 1923 and refurbished last in 1987, carries about 62,000 cars per day between Rosslyn and Georgetown.
