The Seattle Fire Department evacuated some buildings in South Lake Union due to a natural-gas leak from a broken pipe.

Emergency crews responded to the leak at 219 Terry Avenue North about 7:30 a.m. The leak was stopped about 8:20 a.m. and crews were checking buildings for trapped gas.

Seattle Fire Battalion Chief Mike Sharp said the leak was “very large,” but also “a lot to do about nothing” because the gas was easily dissipating. He said he did not know how the gas line broke.

Sharp said the leak was shut off at a meter on the exterior of a building. Gas never got trapped inside surrounding buildings. “A light wind, good atmosphere let it all get out of the way,” he said.

A spokesperson with Puget Sound Energy said the 2-inch line that broke and caused the leak was on private property and not owned by the utility.

A tower is under construction at Terry and Denny Way and a construction worker there said there was a “huge” gas leak. The smell of gas was strong in the area. Nearby buildings were evacuated “as a precaution,” according to a tweet from the fire department.

The leak closed some roadways in the area, as well, but they were all reopened by 9 a.m. Service should return soon to the northbound streetcar tracks on Westlake Avenue near John Street, according to the Seattle Department of Transportation.
