San Francisco's Department of Public Works is investigating a gas leak that took place in the city's Haight-Ashbury neighborhood Monday afternoon.
The department says the incident was caused by contractors who struck a pipeline while doing work on the same major infrastructure project that led to a series of pipeline breaks last year.
Shorty after 2:30 p.m., fire crews responded to a call about a gas leak at Haight and Steiner Streets, according to the Fire Department. In a tweet, the agency said the incident was resolved an hour later.
A contractor hit a gas line in the midst of conducting lateral sewer work, San Francisco Public Works spokeswoman Rachel Gordon said in a text message. Gordon emphasized that the incident did not prompt any evacuations or shelter-in-place orders.
