Sinkhole Appears in San Francisco's Financial District, Interrupts Cable Car Service

A motorcyclist was injured after hitting the sinkhole, which was reportedly caused by a water main break.

A sinkhole appeared on Tuesday evening along the California Street cable car tracks, near the intersection of Montgomery Street in San Francisco's Financial District.
The sinkhole led to the suspension of California Street cable car service on Tuesday night, but service was restored as of Wednesday morning.
A motorcyclist, Arwi Odense, hit the sinkhole and crashed, but was briefly hospitalized and later returned to the scene with his wife to retrieve his motorcycle.
Authorities said that a pipe beneath the area where the sinkholes appeared had been isolated and shut down, but the exact cause remains unclear.
Firefighters said the small sinkhole was caused by a water main break which was shooting water, at one point, 5-10 feet in the air.
