Document Description
Caltrans in cooperation with the San Mateo County Transportation Authority and the City/County Association of Governments of San Mateo County, is considering improvements to US 101 in San Mateo County, including converting existing High Occupancy Vehicle lanes to Express Lanes between Whipple Avenue and Santa Clara County, and the addition of new Express Lanes on US 101 between Whipple Avenue to the I-380 interchange in San Mateo County. The project scope may include removing or replacing existing auxiliary lanes between interchanges, reconstructing ramp connections to US 101, and installing electronic toll collection infrastructure. The Express Lanes would allow HOV's to use the lane without paying a toll, and single occupant vehicles to use the lanes by paying a toll.
