The District Department of Transportation has an emergency construction zone running through this weekend, along Interstate 295 southbound as part of the South Capitol Street Corridor — Frederick Douglass Memorial Bridge Project.

I-295 southbound will have a right lane closed at the Suitland Parkway through Monday, continuing last week’s lane closure. There will be traffic control guides in place for travelers to safely navigate this 24/7 work zone.


The Interstate 395 sign structure improvements project is scheduled Saturday too.

There will be only a single lane traveling on I-395/Southwest Freeway between Maine Avenue and South Capitol Street and intermittent stops of up to 30 minutes northbound between Maine Avenue and the 3rd Street Tunnel as well.

For the closure of the I-395 northbound access ramps from the 9th Street Tunnel, 7th Street SW, and Maine Avenue SW, traffic will be detoured to Maine Avenue SW to access I-395 northbound from South Capitol Street and I-695 eastbound from Washington Avenue SW.

The Maryland Department of Transportation State Highway Administration (MDOT SHA) is set to begin a project on Sunday for the Interstate 70 bridge of US-15. Crews are set to begin at 9 p.m. to brace the planks underneath of the I-70 westbound bridge, which travels over the ramp to southbound US-15.

Crews are expected to close a lane nightly, Sunday through Friday, over the next two weeks. During this time, motorists can expect a single lane of travel on I-70 westbound and southbound US-15/westbound, with US-340 ramp closed.
