After a water main broke early Sunday morning near Van Ness, leaving three apartment buildings between Vallejo Street and Pacific Avenue without H2O for the day, three northbound lanes of San Francisco's main artery were closed down. This morning, however, at 8 a.m., Van Ness reopened. With many of the water lines in the area being "nearly 100 years old," an 8-inch pipe snapped due to years of wear and tear. The rupture, CBS 5 / BCN goes on to report, "the rupture caused the pavement on Van Ness Avenue to bulge and crack due to water pressure below the surface of the roadway."
