The Maryland State Highway Administration said crews are working around the clock to repair pavement on River Road in Potomac between Longacres Preserve Court and Esworthy Road.
River Road is also known as Maryland 190. Drivers traveling in the area will be detoured from to Esworthy Road, then onto Seneca Road and then back onto River Road. Residents who live nearby will be allowed onto River Road up to the point of the closure.

The hole in the road is not technically a sinkhole, said Charlie Gischlar, spokesman for the highway administration. Instead, it was caused by a drain pipe that had been compromised, he said.
Repairs to the road will most likely last through the weekend and into the early part of the workweek, he said. Road crews have to excavate the roadway, remove and replace the pipe and then backfill and resurface the roadway.
