When your block comes up for DC Water’s free lead service line replacement or you want to hire a contractor yourself, it’s important to know what to expect. We’ve got you covered at our next Lead Free DC Virtual Meeting, Wednesday, July 9 from 6 p.m. - 7 p.m.
DC CLEAN RIVERS – POTOMAC RIVER TUNNEL PROJECT
Attention drivers. If you use the ramp from Ohio Drive Southwest to I-66, DC Water will be doing construction that requires the temporary closure of one northbound lane beginning as of today, weather permitting. Drivers will still be able to get onto the highway, and the lane will reopen before the evening rush.
Lane Closure Expected to Impact Commuters from DC, Maryland, and Virginia
DC Water will begin slope stabilization work along Canal Road Northwest starting around mid-August and is needed before construction at the site for part of the Potomac River Tunnel. This work will require the closure of one lane and the sidewalk on Canal Rd between Foxhall Rd and the entrance to Georgetown University.
Ramp Remains Closed Pending Further Assessment
DC Water has completed testing of the Rock Creek Main Interceptor—a major sewer line near the P Street NW ramp to Rock Creek and Potomac Parkway—after a sinkhole appeared on Friday. The results showed no significant leaks or structural issues in the sewer line.

Potomac River Tunnel Project
DC Water will be making two oversized equipment deliveries to support the Potomac River Tunnel Project. This means overnight closures on the 3500 block of Water Street NW—near the Capital Crescent Trail entrance.
The first closure will take place overnight on Tuesday, July 1, and the second on Monday, July 7, weather permitting.
DC Water is advising motorists of an emergency closure to the P Street Northwest Ramp to Rock Creek and Potomac Parkway, due to a sinkhole on the ramp that may compromise the roadway. The closure will begin between 9 p.m. and 11 p.m. tonight until further notice, in order to assess the extent of the void beneath the roadway and near a major sewer line.
