The State Highway Administration said emergency bridge repair work means it will close the three left lanes of the Beltway inner loop between Connecticut Avenue and Georgia Avenue overnight on Wednesday and Thursday.
In a news release, the SHA said the lanes would close at 10 p.m. on Wednesday and Thursday and open no later than 5 a.m. the next morning.
Crews must do emergency repairs on the Beltway bridge over Kensington Avenue, just east of Connecticut Avenue, according to SHA.
The work requires cutting out a large section of concrete and pouring new concrete, which takes a few hours to set.
In the news release, the SHA advised drivers traveling at that time to use East-West Highway as an alternate route.
