Document Description
Note: Per lead agency, Final EIR/EA can be found online at: 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. Specifically, the project would convert the existing single HOV lane in each direction to a single express lane from approx San Antonio Road in Palo Alto, Santa Clara County to Whipple Ave in Redwood City, San Mateo County. The project would also add a new express lane in each direction from Whipple Ave to approx the I-380 interchange in South San Francisco. This would create a total of approx 22 miles of express lanes. The project limits include allowance for the installation for the installation of new overhead tolling system signage beginning approx one mile in advance of the start of the managed lanes in each direction of US 101.
