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 Bay Area County Transportation Agencies (CTAs) and Caltrans, prepared the 2020 RTIP. The 2020 RTIP provides $122 million in new programming capacity for fiscal years 2020-21 through 2024-25. 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. 

Overall, MTC’s 2020 RTIP includes funding for eight new projects in five of the nine Bay Area counties. The 2020 RTIP focuses on maintaining aging transit assets in a state of good repair. In Alameda County, AC Transit programmed $13 million for the Replacement of Transbay Buses project. In San Francisco, SFMTA programmed $8 million for the mid-life overhaul for various transit vehicles throughout the City. The 2020 RTIP also includes focused investments on the highway system supporting proposed SB1 competitive program nominations.

The Commission approved the 2020 RTIP Program of Projects on December 18, 2019, and is available here. The CTC will hold two hearings for the 2020 STIP (of which the 2020 RTIP is a part) in early 2020, and will consider adoption the 2020 STIP on March 25, 2020.

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

MTC receives STIP investment proposals from the county transportation agency (CTA) 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.
