Concerning the statewide multimodal transportation plan.

SB 6333 requires Washington's Department of Transportation to develop a statewide multimodal transportation plan every three years, starting in 2027. The plan must cover both state-owned infrastructure (highways, ferries) and state interests in other transportation modes (aviation, rail, ports, public transit), with specific focus on reducing congestion, improving safety, and integrating different transportation types. It mandates environmental reviews for potential impacts (like wetlands or air quality) and requires coordination with local governments and environmental agencies. The bill also adds new reporting requirements for the department to share plan details and progress with the legislature and financial management office annually. This directly affects the Department of Transportation and indirectly impacts local governments, transportation providers, and environmental agencies involved in planning.
