The road is shut down in the area of Spring Valley Country Club, from the top of the hill on both sides of the valley, the Street Department said.
The closure was planned initially for the safety of workers doing weeding in the area, the department said. The planned closure happened to coincide with a water main break, however.
According to the Street and Safety departments, the maintenance closure was planned to last until about 2 p.m., but fixing the water main will take most of the day.
The city said there is no boil alert, and water service shouldn’t be disrupted for anyone.
