The westbound roadway was closed from Atherton Avenue to U.S. Highway 101 since late last week, according to Caltrans officials, and only one lane in the eastbound direction remains open in the same corridor as of 7 a.m.
Caltrans advises commuters in the area to anticipate delays and allow for extra travel time for any lane closures that remain in effect.
