SF: Stockton tunnel shut down as crews repair ruptured water main


San Francisco’s Stockton Tunnel is closed this afternoon because of a water main break on the side of the tunnel closer to Union Square, a San Francisco Municipal Transportation Agency spokeswoman said.

A leak was reported just before noon on a 4-inch main near Stockton and Sutter streets, SFPUC spokeswoman Suzanne Gautier said.

Buses were the only vehicles allowed through the tunnel for a short period as water bubbled onto the street, she said.

Around 1:30 p.m., crews were making repairs to the line and the tunnel had been shut down to all vehicles, SFMTA spokesman Paul Rose said.

The 30-Stockton and 45-Union bus lines are rerouting around the tunnel, he said.

There may be damage to the pavement near the tunnel, according to Gautier.

Rose said it is too early to confirm if Central Subway construction is cause of the break.

He said a boring machine is located about 100 feet north of where the leak occurred. The machine is being used underground to carve out a tunnel for the new subway line that will eventually connect passengers from the San Francisco Caltrain Station to Chinatown.
