Don’t even think about trying to drive on the Capital Beltway’s Inner Loop near Telegraph Road this weekend, traffic officials warn.

Traffic on the highway will be reduced to just one lane from 9 p.m. Friday through 5 a.m. Monday as crews make emergency repairs to a nearly 50-year-old overpass bridge. The Telegraph Road ramps onto the Inner Loop also will be closed, if the weather holds out for the road work.
