Statewide Transportation Improvement Program (STIP)

The STIP is a four-year prioritized multimodal transportation program compiled of state, local, tribal and public transportation projects that include highways, streets, roads, rail, transit-hubs, park & rides, bridges, sidewalks, bike lanes, trails and safety.

The STIP is a calendar year document and is developed on an annual basis. The draft STIP is available for public review and comment in November. The final STIP is submitted to Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) in December and approved in January. STIP amendments are submitted to FHWA and FTA for approval January through October and are available for public review and comment concurrently for 10 calendar days.

Draft 2024-2027 Statewide Transportation Improvement Program (STIP)

Each year, the Washington State Department of Transportation develops the Statewide Transportation Improvement Program from local, metropolitan planning organization (MPOs), regional transportation planning organizations (RTPOs) and county transportation improvement programs (TIPs). This compilation of prioritized transportation improvement projects is now ready for review and public comment.

The draft 2024-2027 STIP (PDF 11MB) is a four-year program of multimodal transportation projects identified through state, metropolitan, regional, tribal, and local agency planning processes.

Projects that use Federal Highway Administration or Federal Transit Administration funds must be included in the STIP to authorize the expenditure of federal funds. Also, included are regionally significant projects funded through the Washington State Legislature Connecting WA transportation package and the Move Ahead Washington transportation package. More than 1,200 statewide transportation improvement projects using $3.8 billion in federal funds are included in the 2024-27 STIP.

The Washington State Department of Transportation will accept comments for the draft 2024-2027 STIP until 5 pm Tuesday, Dec. 19. WSDOT will send any comments it receives to the respective local agency, metropolitan or regional planning organization for their consideration.

The comment period is the final step of a public engagement process that began locally during development of the individual transportation improvement programs. The collaborative effort between WSDOT, local agencies, metropolitan and regional transportation planning organizations ensures projects are consistent with local, regional, and state long-range plans.

Some county projects are not included in the draft STIP, as counties are required by state law to complete their transportation improvement programs by the end of December, so those projects are amended into the STIP in January.

The current 2023-26 STIP can be viewed using the Searchable Web Database below and a similar, searchable database of the 2024-27 STIP will be created in January 2024, following FHWA and FTA approval.

Written comments can be sent to: Nancy Huntley or Steve Ahlsten, WSDOT, P.O. Box 47390, Olympia WA 98504-7390, or by email at Hqlpstip@wsdot.wa.gov.
