Caltrans’ US 101 Managed Lanes Project Awarded  Envision® Silver for Sustainability

Washington, D.C. — July 20, 2021 — California Department of Transportation (Caltrans), in partnership with the San Mateo County Transportation Authority (SMCTA) and the City/County Association of Governments of San Mateo County (C/CAG), is currently constructing express lanes on U.S. 101 in San Mateo County within the existing right-of-way. The existing high-occupancy vehicle (HOV) lanes will be converted into express lanes from the Santa Clara County/San Mateo County line to Whipple Avenue. Caltrans is also adding an additional lane to northbound and southbound U.S. 101 from Whipple Avenue to I-380. This project will create 22 miles of express lanes in each direction of U.S. 101 in San Mateo County and provide a seamless transition to the express lanes being constructed in Santa Clara County.

Caltrans evaluated the sustainability performance of this project and used Envision to identify additional opportunities to improve the project’s sustainability and resiliency profile. Caltrans submitted this project to the Institute for Sustainable Infrastructure for Envision verification.  Subsequently, they earned an Envision Silver award—a testament to Caltrans’ commitment to and leadership in sustainability.
