DC WASA Work to Impact Traffic on Rock Creek Parkway

January 22, 2010

The DC Water and Sewer Authority (DC WASA) will be performing construction, beginning on Monday, February 1, that will require a temporary lane closure on Rock Creek Parkway for the next few months. The closure will be limited to off-peak hours, but traffic delays are still possible and motorists are encouraged to use alternate routes if possible.

The planned work is part of the Rock Creek Sewer Separation and Water Main Replacement project, CSO 037. Disruption should be expected between the hours of 10 a.m. and 3 p.m. and the project will take a minimum of 60 days to complete.

During construction, the northbound lane on Rock Creek Parkway will be closed for about 500 feet at Waterside Drive, N.W. Standard traffic control devices will be in place.

DC Water has completed sludge removal on a section of the C & O Canal between locks 13 and 14, which was used as a bypass to divert wastewater around the collapsed section of the Potomac Interceptor and back into the pipe further downstream. Crews are now constructing an access bridge to this section of the canal to allow soil removal to begin.
