WSSC Replaces Aging Water Mains Along US 29 in Downtown Silver Spring

Two-Year Project will Enhance Reliability and Service to Customers

| News Release



Work will Impact Traffic Along North and Southbound US 29

LAUREL, Md. – August 15, 2017: Calvin Coolidge was president when WSSC first installed some of the 91-year-old water mains underneath US 29 (Colesville Road) in downtown Silver Spring. Starting next week, weather permitting, WSSC will begin replacing nearly two miles of the old 16-inch cast iron pipes with brand new zinc-coated ductile iron pipes, which are expected to last approximately 100 years. The $3.4 million project extends from MD 97 (Georgia Avenue) north to I-495 (Capital Beltway).

Water main replacement projects involve heavy equipment, digging, noise, lane closures and parking restrictions. If necessary, temporary lines will be installed and connected to homes and businesses to provide water during the project. If temporary lines are used, customers will experience a brief interruption in service when the new main is activated. WSSC will notify customers prior to this brief interruption.

Work will impact traffic along north and southbound Colesville Road during off-peak hours. Motorists are encouraged to plan ahead as single and double-lane closures will cause delays. Flagpersons, cones and signs will alert and guide motorists through this section of Colesville Road. WSSC urges motorists to drive safely when traveling through work zones. Parking along Colesville Road will not be permitted in areas where crews are working.

Working closely with the Maryland State Highway Administration, work will take place weekdays between 9:30 a.m. and 3:30 p.m. Weekend work may occur between 9:00 a.m. and 9:00 p.m., and occasional evening work also may take place between 9:00 p.m. and 5:00 a.m. WSSC will notify residents and businesses prior to any evening or weekend work.

Water main replacement work should be complete in spring 2019, weather permitting. Final restoration of sidewalks, roadways and landscaping is weather dependent and takes place within 90 days following completion of the pipe work.

WSSC has engaged in extensive public outreach to inform customers and business owners about this project. More information can be found at: To help inform customers about what to expect during water main replacement work, WSSC created this short video.
