The D Street off-ramp leading from the 12th Street Expressway will be closed between Saturday at 7 a.m. and Sunday at 7 p.m.

While the off-ramp is closed, there will be a detour in place, according to the District Department of Transportation: Traffic will be directed through the 12th Street SW tunnel to Constitution Avenue NW before turning right on Constitution Avenue, making a right on 7th Street and traveling to D Street SW.

The ramp closure, taking place before the tunnel, will allow roadway work to take place nearby, officials said.
