Sangamore Road closures expected through April for pipeline replacement

A major natural gas pipeline replacement project on Sangamore Road near Walhonding Road in Bethesda will require lane and road closures on that stretch of Sangamore through mid-April. Washington Gas and contractor NPL will be performing the work between 9:00 AM and 3:00 PM on weekdays, which is when those closures will take place as-needed.

During the closures, drivers will have to detour from Massachusetts Avenue onto Marlyn Drive to make a right onto Namakagan Road, and then turn back onto Sangamore from Namakagan. Orange directional signs are now in place along the detour route. Sangamore Road drivers trying to reach Massschusetts Avenue will complete the detour route in reverse order by turning onto Namakagan.
