Tolling began Friday morning on new U.S. Highway 101 express lanes between South San Francisco and Sunnyvale.
The new lanes will be running on Highway 101 on weekdays from 5 a.m. to 8 p.m. between Interstate Highway 380 in South San Francisco and North Mathilda Avenue in Sunnyvale.
Solo drivers who want to use the express lane must have a standard FasTrak or a FasTrak Flex toll tag, while carpoolers and motorcycles must have the FasTrak Flex toll tag set in the proper position to travel at a discount.
The lanes, constructed by Caltrans in partnership with the San Mateo County Transportation Authority and the City/County Association of Governments of San Mateo County, are meant to encourage carpooling or transit use as well as to improve travel times and reduce congestion on the highway.
