DC Water will be doing construction as part of a sanitary sewer rehabilitation project on Clara Barton Parkway in Maryland from Sept 8 - Oct 10, 2025, which may cause delays inbound near the I-495 Beltway interchange. One lane will be closed in the work zone to reline an 800-foot section of the sewer line, known as the Potomac Inteceptor. Access to the inner and outer loops of the Beltway will remain available. Additional lane closure may be necessary intermittently through Oct 31, 2025.
