The state government operates on a fiscal biennium that begins July 1 of each odd-numbered year.  Supplemental budgets are typically enacted in each of the following two years after adoption of the biennial budget.  Appropriations are made in the biennial and supplemental transportation budgets for the operation and capital expenses of state transportation agencies and programs.

Appropriations totaling $13.5 billion are made for state transportation agencies and programs for the 2023-25 fiscal biennium from a number of transportation accounts.  Capital-related appropriations total $7.3 billion, and operating-related appropriations total $6.1 billion.  Appropriations for the fiscal biennium include:  $10.1 billion for the Washington State Department of Transportation; $1.8 billion for debt service; $650 million for the Washington State Patrol; and $431 million for the Department of Licensing.  Fund transfers and other provisions are made.  Additional detail can be found at fiscal.wa.gov.

Appropriations are adjusted for state transportation agencies and programs for the 2021-23 fiscal biennium.  Overall appropriations are reduced by $1.7 billion from $12.2 billion to $10.5 billion.  Capital-related appropriations are reduced by $1.6 billion, and operating-related appropriations are reduced by $39 million.  Fund transfers and other provisions are adjusted.

The Governor vetoed several items in the 2023-25 Biennial Transportation Budget and 2023 Supplemental Transportation Budget.  See veto message for details.
