Regional Agencies Invite Public Comment As Planned U.S. 101 Upgrades on Peninsula Take Shape

John Goodwin, MTC (415) 778-5262

The Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG) today released proposed draft amendments to the long-range regional transportation and land use plan known as Plan Bay Area 2040 and to the 2017 Transportation Improvement Program (TIP) that would modify the scope and projected cost of the planned U.S. Highway 101 Managed Lanes Project in San Mateo County. MTC and ABAG invite Bay Area residents to comment on the draft amendments. Comments must be received no later than Wednesday, February, 21, 2018.

Work planned by the City/County Association of Governments of San Mateo County and the San Mateo County Transportation Authority to upgrade U.S. Highway 101 in San Mateo County is currently described in Plan Bay Area 2040 as:

“Modify existing lanes to accommodate an HOV lane from Whipple to San Francisco County Line and/or an Express Lane from approximately 2 miles south of the Santa Clara County Line to San Francisco County Line. Work may include shoulder modification, ramp modifications and interchange modifications to accommodate an extra lane. Work will be phased.”

The proposed amendments to Plan Bay Area 2040 and the TIP would update the cost, clarify the project description, and change the assumptions about the number of auxiliary lanes and general purpose lanes in some segments of U.S. Highway 101 to accommodate an express lane in each direction. The proposed amendments to Plan Bay Area 2040 and to the TIP necessitate a new Transportation-Air Quality Conformity Analysis, which also was released today for public comment through February, 21.

Interested residents may go to and click on the links in the “Related Documents” box to review the proposed draft amendments and other pertinent materials. Written comments may be addressed to MTC-ABAG Project Manager Adam Noelting at 375 Beale Street, Suite 800, San Francisco, CA 94015. Comments also may be sent via e-mail to or by fax at 415.536.9800.
