The Senate Bill 1 program invests an estimated $5 billion annually, split between state and local investments. This funding can only be spent on improving transportation infrastructure in California. SB 1 has no built-in sunset clause, meaning it does not automatically expire.
The gas tax rates used in this calculator are based on changes effective July 1, 2026.
Through the Infrastructure Investment and Jobs Act (IIJA), California will receive federal infrastructure funding based on formula and discretionary grants.
Formula grants are allocated based on a formula established by law, rather than through a competitive process.
Discretionary grants are awarded to states or projects through a competitive selection process.
Based on formula funding alone, the IIJA will bring California an estimated $41.9 billion over 5 years from Federal Fiscal Year (FFY) 2022 through FFY 2026.
Please note that totals may vary slightly due to rounding of decimal values.
**On January 21, 2025, the Invest.gov website was taken down. Invest.gov is our source for federal project data. As of now, the situation remains fluid. As things stabilize and we receive more information from our federal partners (such as the Federal Highway Administration, Federal Transit Administration, Federal Rail Administration, etc.), Caltrans and Building CA will make every effort to keep the federal data current. We will provide updates as soon as we receive more definitive guidance from our federal partners. Thank you for your patience.

Caltrans has three distinct programs to assist small businesses to compete more effectively for its contracting and procurement dollars: Small Business (SB), Disabled Veteran Business Enterprise (DVBE), and Disadvantaged Business Enterprise (DBE).
Infrastructure Investment and Jobs Act (IIJA) funding for the DBE program will remedy ongoing discrimination and the continuing effects of past discrimination in federally-assisted highway, transit, airport, and highway safety financial assistance transportation contracting markets nationwide.
The DBE program's primary remedial goal and objective is to level the playing field by providing small businesses owned and controlled by socially and economically disadvantaged individuals a fair opportunity to compete for federally funded transportation contracts. To learn more, visit the DBE Program on the U.S. Department of Transportation website.
From October 1, 2024 - September 30, 2025, Caltrans has awarded 21.15 percent of contracts to Disadvantaged Business Enterprise (DBE) firms. Our goal for Federal Fiscal Years (FY) 2025-2027 is 21.35 percent.
Caltrans has had similar success with state-funded Small Business and Disabled Veteran Business Enterprise programs. For more information, check .
