A stretch of Sepulveda Boulevard was closed early Thursday as Southern California Gas Co. crews worked around the clock to conduct pressure tests on a natural gas pipeline.
The Gas Co. has been conducting the tests, and replacing some pipeline sections, on the Sepulveda Boulevard line for weeks, but the work has been done only at night.
However, beginning at 5 p.m. Wednesday, crews began round-the-clock testing on the line, resulting in lane closures at Sepulveda's intersections with Wilshire and Pico boulevards through Thursday.

Motorists were advised to anticipate slower-than-usual traffic on Sepulveda. Digital signs and flaggers will be in place to direct motorists. After the round-the-clock work ends, the project will return to nighttime-only work, according to the Gas Co.
The gas pipeline work is taking place along a relatively short section of Sepulveda, which, at nearly 43 miles, is L.A. County's longest street.
