As part of the San Mateo 101 Express Lanes Project, Caltrans will be replacing five overhead sign structures on U.S. 101, which will require construction crews to close one direction of the freeway at a time between Millbrae Avenue in the City of Millbrae and South Airport Boulevard in the City of South San Francisco for five nights during the week of February 28th (from 11:00 PM to 4:00 AM), when traffic volumes are usually light. Motorists are advised to be familiar with the proposed detour routes and allow for extra travel time.
Freeway Closures:
Southbound U.S. 101 from South Airport Boulevard to San Bruno Avenue is anticipated to be closed overnight on Sunday, February 28th, Monday, March 1st, and Tuesday, March 2nd to safely remove three sign structures.
Northbound U.S. 101 from Millbrae Avenue to San Bruno Avenue is anticipated to be closed overnight on Wednesday, March 3rd, and Thursday, March 4th to safely remove two sign structures.
Closure locations and times will be displayed on changeable message signs at least one week in advance. At no point will both the northbound and southbound directions of U.S. 101 be closed at the same time. All construction activities are subject to change without notice.

Closure locations and times will be displayed on changeable message signs at least one week in advance.

Motorists will be directed to exit the freeway in advance of the closed freeway sections, and detour signs will be in place to clearly guide them through city streets until they get back on the freeway. Detour routes have been carefully selected with input from local jurisdictions to minimize impacts to nearby residents. See the detour maps below for the exact detour routes.

At no point will both the northbound and southbound directions of U.S. 101 be closed at the same time.
