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.
