As of 11:50 a.m., that shelter-in-place order has been lifted.
Kensington police issued an alert shortly after 9:15 a.m. about the gas main break in the area of Cambridge and Yale Avenues.
PG&E says that a third-party digging project hit a gas line, and crews were at the scene working on the situation.
People living in the area were ordered to shelter in place and motorists were advised to avoid the area until the main is repaired.
