San Mateo County - Caltrans will continue median barrier upgrade work on U.S. 101 between the San Mateo/ Santa Clara County line to Whipple Ave. Caltrans will close a 2.5-mile section of the North and Southbound Express Lanes (#1 lane) beginning on Friday, September 27, 10:00 PM thru Monday, September 30, 5:00 AM. This is the sixth of nine 55-hour single lane closures scheduled to complete barrier upgrade and related work. Each closure work limits will be a 2.5-mile section. All work will be done outside of Express Lane operational hours. An additional lane may be closed at various times during the closures to facilitate equipment and materials.

Caltrans appreciates the cooperation and understanding of the traveling public as we make progress on upgrading the median barrier along U.S. 101 in San Mateo County.

Utilizing weekend closures significantly reduces the number of nighttime closures needed and increases safety for the workers and the motoring public.
