San Mateo 101 Express Lanes Closure Project
February 2021
Caltrans is scheduled to implement full Highway 101 North and South closures near the Airport starting Sunday, February 28 through Thursday, March 4, 2021, between the hours of 11:00 p.m. to 4:00 a.m. The full freeway closures are needed to remove five overhead sign structures which span the Highway 101 traffic lanes near the Airport. This work is part of the San Mateo 101 Express Lanes Closure Project which will reduce traffic congestion, encourage transit use and carpooling on Highway 101 in San Mateo County.
