Manhole repair work apparently caused quite the ruckus on Monday night around Old Georgetown Road and Woodmont Avenue.

We got a few tips from readers wondering what the jack hammering around 9 p.m. was for. A WSSC rep pointed us to this map of ongoing repairs and pipe replacement projects.

One tipster wrote, “It started at about 9pm and it just won’t stop! I have no idea how to file a complaint about it.”

WSSC crews are doing work on a number of manholes in the immediate area, work that requires some minor excavation.

The project descriptions on the website provide some more information, plus contact information for the project manager.
