Drivers in San Mateo County should brace for delays as Caltrans announces a scheduled traffic control on the Tom Lantos Tunnels in Pacifica. The inspection work is slated to start today and will continue through the week until Friday.

The nighttime disruptions, affecting travel from 8 p.m. to 4:30 a.m., will necessitate alternating one-way traffic, with northbound lane closures set for the first two nights and southbound closures during the latter half of the week.

According to the San Mateo County Sheriff's Office, commuters are encouraged to plan accordingly as delays are anticipated. Flaggers will be present to guide motorists through the construction area.
