Colesville Road Transmission Water Main Replacement (TWMR) Project

Project Scope:

WSSC Water will be replacing and relocating approximately 1.88 miles (1.53 miles of 16/20-inch Transmission Mains and 0.25 miles of Distribution Water Mains) of water mains on US 29/Colesville Road and the connections to its intersecting streets. The project will extend from Georgia Avenue to the entrance of the Beltway.

*As a result of unexpected difficulties other utilities have encountered while digging through the rock below the road surface, WSSC Water has decided to change our starting point to Spring Street, so we do not further delay our project or conflict with other projects taking place on Colesville Road.

The new water mains will be zinc-coated, ductile iron pipe wrapped in a protective coating, giving the pipes a life expectancy of at least 100 years.

Construction began September 2017 and is expected to be completed by Spring 2019, weather permitting.

Traffic Impacts: Motorists are encouraged to plan ahead because single and double-lane closures will cause delays during work hours.

Parking: Parking restrictions will be in effect in construction zones during working hours and will be denoted by “No Parking” signs.

Access to homes and businesses will be maintained at all times.

Project Update: August 26, 2019

Originally, WSSC Water anticipated the project would be completed by Summer 2019, however, as a result of difficulties encountered while digging through the rock below the road surface, we have had to adjust our schedule. At this time, WSSC Water anticipates pipe installation will be completed Fall 2019.

Beginning Monday, August 26, 2019, we are adding overnights to the core working hours in an effort to adhere to our updated project completion date. In the event of inclement weather, work will not take place. Residents and business owners will be informed regarding changes in the schedule.

NEW WORK HOURS

Day Work: Monday-Friday, 9:30 a.m. to 3:30 p.m.

Night Work: Monday-Friday, 9:00 p.m. to 4:00 a.m. These hours will be in effect until Friday, September 13, 2019

Weekend Work (starting August 31, 2019): Saturdays, 9:00 a.m. – 5:00 p.m.; Sundays (as needed), 9:00 a.m. – 5:00 p.m.

NOTE: Work will not take place on Federal or WSSC Water Holidays or during inclement weather (heavy rain or freezing temperatures).

WHAT TO EXPECT

Work will take place at the intersection of Fenton Street and Colesville Road/US 29.

Motorists are encouraged to plan ahead as single- and double-lane closures will cause delays during work hours along southbound Colesville Road.

Project Update: September 19, 2018

As a result of the excessive rain, no construction activities relating to this project have taken place over the past week. Once work resumes, crews working for WSSC Water will continue water main installation along Colesville Road at approximately Greyrock Drive. As a result of this work, the far two southbound lanes of Colesville Road will be closed during working hours. WSSC Water anticipates this work being completed next week, weather permitting.

Project Update: November 1-30, 2017

WSSC Water is adding Saturdays to the core working hours. This change in work hours begins this Saturday, November 11, 2017. No work will take place on November 18th and 25th to accommodate Thanksgiving holiday activities. In the event of inclement weather, work will not take place. Residents and business owners will be informed regarding changes in the schedule.

Work Hours: Monday-Friday, 9:30 a.m.–3:30 p.m.; and Saturdays, 9:00 a.m.–5:00 p.m.

Work will take place along southbound Colesville Road between Woodside Drive and Sligo Creek Parkway.
