Drivers should be aware of daytime lane closures on the 9th Street Expressway as they head to I-395 through the end of February.

The District Department of Transportation said it will perform preventative maintenance on the roadway under D Street, forcing the closure of the left lane of southbound 9th Street Expressway from 10 a.m. to 3 p.m. In addition, there will be one lane closed on the eastbound ramp from D Street to I-395.

These closures began Wednesday and will continue through Feb. 28, DDOT said.

It warned of the potential of “moderate to heavy” delays for drivers.
