WASHINGTON (WUSA9) -- Crews worked feverishly overnight to repair a 20-inch water main that burst early Saturday morning.
Crews had to drill down to the gushing pipe that took several hours to shutdown on 17th and Rhode Island Avenue Northwest.
When they peeled back the road they found the pipe with a 5-6 foot hole.
George Hawkins, DC Water General Manager, "we haven't had many problems on this road and we wouldn't have expected it. But there's a large excavation directly adjacent to it."
They're looking at what caused the century old pipe -- installed in 1897 -- to break. DC Water General Manager George Hawkins says they haven't ruled out anything including, the pipe's age and nearby construction work.
This is also the same site where a construction worker had to be rescued, a week and a half ago.
Rescue crews carefully lifted him up from where he fell near blasting cords 50 feet down.
