SAMMAMISH, Wash. -- A large gas leak has closed an important neighborhood road in Sammamish, an official for the city said.

At 10:55 a.m., a substantial brown cloud was seen rising above the road just north of the Skyline High School campus.

Police said the road will remain closed until Puget Sound Energy can turn off the gas in that area.

No word has been released on the cause of the leak, but construction work is taking place in the vicinity
