Leaky Bay Bridge water main repaired

San Francisco Public Utilities Commission crews Monday afternoon repaired a 10-inch water main on the Bay Bridge that had been leaking water onto the lower deck since morning.

SFPUC spokesman Tony Winnicker said at about 1:30 p.m. that crews had repaired two leaky pipe fittings on the main, which runs beneath the upper deck of the bridge between San Francisco and Treasure Island.

The pipe supplies water to Treasure Island from San Francisco, but Winnicker said Treasure Island has 3 million gallons of stored water and that residents didn't see their water service affected.

The pipe began leaking sometime before 10 a.m., splashing water down onto the left lane of the lower, eastbound deck. That lane, however, was already closed to cars, minimizing the leak's impact on traffic, Winnicker said.

Crews had planned to make a temporary fix before the evening commute then follow up with permanent repairs later Monday night, but Winnicker said that turned out to be unnecessary.

“Two (leaks) in the same day is very unusual,” Winnicker said. “But it turned out to be a very easy fix.”

Winnicker said the 60-year-old pipe was inspected over the Labor Day weekend and appeared to be fine.
