The accident happened shortly after 8 a.m. at a construction site near La Jolla Village Drive and Regents Road. Crews working with an excavator hit an underground gas line, causing the leak.
Police closed lanes in the intersection adjacent to the leak and were working to keep pedestrians and vehicles far enough away to prevent sparks from igniting the gas. As of 9:40 a.m., crews from San Diego Gas and Electric were working to shut off the gas. Officials estimated that lanes would remain closed in the area until at least 10:30 a.m.
Officials were not evacuating people in a business park across the street from the leak, but workers were monitoring the are to make sure gas levels remained safe.
