OAKLAND -- Three water main breaks in various locations around the city Monday may have been linked to a change in pressure during work on an aqueduct, said a spokeswoman for the East Bay Municipal Water District.

The most significant break flooded Kingston Avenue and forced road closures Monday morning near the Piedmont border, officials said. A Honda Odyssey van parked on the street was towed because authorities were worried about cracks forming beneath it, and that it might fall into a sinkhole. No sinkholes were reported Monday afternoon.

A break at 47th Avenue also closed part of that street between Melrose and Ygnacio avenues. It was not immediately known when that stretch would be reopened.

A pipe also broke at Walavista and Arimo avenues but no street closures were required.

Police and East Bay Municipal Water District crews responded to the Piedmont border water break about 10:32 a.m. Water was gushing from several spots near the intersection of Kingston and Monte Cresta avenues, and most of the flow was stopped within an hour, officials said.

The main that broke was a 6-inch cast-iron pipe dating back to 1910, said EBMUD spokeswoman Abby Figueroa. Repair work was ongoing all day Monday.

Figueroa said all the pipes that broke Monday are old. It was not yet known how many gallons of water were spilled, Figueroa said. All the breaks are in various stages of repair.

Figueroa said Kingston Avenue between Monte Vista and Monte Cresta would be closed to all traffic until about 7 p.m. Monday.
