LOS ANGELES (CBS) — Beginning Monday, delays are expected around Sepulveda Boulevard in Westwood for the next few months.

One southbound lane of Sepulveda is closed from Montana Avenue to Moraga Drive as crews need to move a gas line that runs underneath.

The closure is part of the billion-dollar project to widen the 405 Freeway through the Sepulveda Pass.

Crews are scheduled to work from 7 a.m. to 7 p.m.
