101 Express Lanes
The San Mateo 101 Express Lanes Project is 22 miles of express lanes in both directions on U.S. 101 from the San Mateo County/Santa Clara County Line to I-380 in South San Francisco. The San Mateo 101 Express Lanes will seamlessly connect to the express lanes being constructed in Santa Clara County
A goal of the express lanes is to enable travel speeds of 45 mph or greater, resulting in reduced and more reliable travel times.
Key Project Benefits:
* Reduce congestion in the corridor
* Increase person throughput (the number of people moved)
* Encourage carpooling and transit use
* Improve travel time and reliability for express lane users
* Use modern technology to manage traffic
* Make upgrades to pavement and lane striping
