Beginning this week and continuing through Friday, September 4th, DC Water will temporarily close one lane overnight on Clara Barton Parkway at the Maryland-D.C. border. The closures are necessary to allow crews to safely begin geopolymer work, a concrete-like material, applied inside the sewer line as part of emergency repairs to a section of the Potomac Interceptor. 

To reduce traffic delays, most of the work will happen in the evening and overnight when fewer cars are on the road. Only one lane will be closed, and the other lanes will remain open for traffic in both directions.  Drivers should slow down, watch for signs and flaggers, and expect some short delays.

This section of pipe was identified as part of a new, ongoing effort to inspect the entire system and prioritize repairs. DC Water moved this area up for emergency repair based on the inspection results. Crews will repair about 400 linear feet of pipe in this area.

Details:

• Location: Clara Barton Parkway at the Maryland-D.C. border
• Time: 8 p.m. and 4 a.m.
• Duration: Beginning this week and continuing through Friday, September 4th
• Traffic impact: One lane may be closed at a time. Drivers should expect short delays and follow the direction of traffic flaggers.

The repairs are part of the 10-year, $625 million Potomac Interceptor Rehabilitation Project included in DC Water’s Capital Improvement Program to invest in and improve aging water and sewer infrastructure.
