Clara Barton Parkway to be repaved starting July 27

The National Park Service will begin a major repaving project on Clara Barton Parkway on or about July 27, 2020. Contractors will repave the parkway between Carderock and Chain Bridge between then and the end of the year. Paving will begin at Carderock, and proceed eastward toward the District, according to Bethesda-Chevy Chase Regional Services Center Director Ken Hartman.

NPS says the parking area will temporarily close at Lock 7 along the C&O Canal. The project will also include installing new signage, painting brighter/clearer lane lines and striping, reconfiguring lanes, and trimming vegetation that is close to the road.

Expect non-rush hour lane closures, as well as temporary, 2-week ramp closures. Signs will direct you to the next available exit ramp. The Federal Highway Administration is partnering with the NPS on the project.
