State Transportation Improvement Program

The State Transportation Improvement Program, or STIP, is a five-year investment plan for state transportation money.

To keep the plan fresh, the STIP is updated every two years. 

The most recent STIP was adopted in 2018 and development of the 2020 STIP is now underway.

Any capital project — from a new roadway or new bike path to a highway expansion or rail line extension — may be included in the STIP to receive state funding.


Regional spending plans — developed by MTC for the Bay Area and by other agencies elsewhere in California — account for 75 percent of the STIP.

These are known as Regional Transportation Improvement Programs, or RTIPs.

The remaining 25 percent of the STIP is a statewide spending plan known as the Interregional Transportation Improvement Program, or ITIP. The California Department of Transportation (Caltrans) develops the ITIP to fund projects that connect metro areas or cross regional boundaries.

Together, the ITIP and the various RTIPs make up the STIP.

Bay Area Investments

MTC, in cooperation with County Congestion Management Agencies (CMAs) and Caltrans, prepared the 2018 RTIP. The 2018 RTIP provides $291 million in new programming capacity for fiscal years 2018-19 through 2022-23. Senate Bill 1 (SB1), stabilized the funding for the State Highway Account that is directed to fund the STIP. Thanks to SB1 the counties of the San Francisco Bay Area and MTC are now able to program STIP funds to new and previously deleted projects.

One of the focuses of the 2018 RTIP is maintaining aging transit assets in a state of good repair. In Alameda and Contra Costa Counties, BART has $16.8 million for two Station Modernization projects to improve the 19th Street Oakland and Concord stations. In San Francisco, SFMTA programmed nearly their entire RTIP share, $13.6 million, for the maintenance and rehabilitation of various light rail lines throughout the City. The proposal also includes focused investments on the highway system supporting SB1 competitive program applications.

The Commission approved the 2018 RTIP Program of Projects on December 20, 2017, and is available here. The California Transportation Commission (CTC) held two hearings for the 2018 STIP (of which the 2018 RTIP is a part) in February 2018, and will consider adoption of the 2018 STIP at its March 21-22, 2018 meeting.

Every California county receives a designated amount of STIP funding — known as a county share.

MTC receives STIP investment proposals from the congestion management agency in each of the nine Bay Area counties, and reviews them for consistency with the goals of Plan Bay Area 2040, the region's long-range plan that charts a course for transportation investment and land-use priorities through the year 2040.

If all the county proposals pass muster, MTC compiles them into a single Bay Area RTIP.

Once MTC assembles the Bay Area RTIP, it then forwards the proposal to the California Transportation Commission for review.

The CTC must either accept the RTIP in its entirety or send it back to MTC for revision. The CTC similarly reviews the ITIP proposal submitted by Caltrans.
