SM 101 Express Lanes Policy and Governance


Express Lane governance:

The management and operation of the Express Lanes is governed by the San Mateo County Express Lanes Joint Powers Authority (SMCEL JPA), a six member joint powers authority consisting of three San Mateo County Transportation Authority (SMCTA) Board members and three City/County Association of Governments of San Mateo County (C/CAG) Board members.

Board meeting material and information is available on the C/CAG website.


Planning and Policy Decisions:

Equity - The SMCEL JPA will be conducting a study to assess the equity needs, including those of the lower income community, in the U.S. 101 express lanes project area. The study is slated to begin spring 2020 and will take approximately 12 months to complete. The SMCEL JPA will then consider recommendations and/or strategies that result from the study.

Toll Ordinance – Prior to the opening of the lanes, the SMCEL JPA will develop toll policies, including rates for the SM 101 Express Lanes, and establish a Toll Ordinance and a toll collection process. The Toll Ordinance will also establish evasion policies. More information on how the tolling system will function is available under Frequently Asked Questions.


Construction:

SM 101 Express Lanes Project

Project Overview:

SM 101 Express LanesCaltrans is constructing express lanes on US 101 in San Mateo County in partnership with the SMCTA and C/CAG.

The existing HOV lanes will be converted into express lanes from the San Mateo County/Santa Clara County line to Whipple Avenue in Redwood City. Caltrans will add an additional lane to northbound and southbound US 101 from Whipple Avenue to I-380 in South San Francisco, and then convert the far left lanes to express lanes.

Ultimately, this will create 22 miles of express lanes in San Mateo County and provide a seamless connection to the express lanes being constructed in Santa Clara County.

Project Fact Sheet:


Project Benefits:

  • Encourage carpooling and transit use
  • Improve travel time and reliability for express lane users
  • Increase person throughput (the number of people moved)p
  • Use modern technology to manage traffic
  • Reduce congestion in the corridor
  • Make upgrades to pavement and lane striping


Schedule

The project is being constructed in two phases. Construction on the southern phase, which extends from the Santa Clara/San Mateo County line to Whipple Avenue began in March of 2019 and is expected to be completed in late 2021. Construction on the northern segment that runs from Whipple to I-380 began in February2020 and is scheduled to be completed in late 2022. The express lanes will open for operations once construction is complete.
