Transportation Improvement Program

The Council's primary role in transportation funding is to establish regional priorities. Transportation 2040, the Regional Transportation Plan, identifies long-term transportation needs and funding priorities. Local cities and counties develop comprehensive plans and capital improvement programs that advance Transportation 2040 projects along with local priorities. The CDTC also selects transportation projects through a competitive grant process to receive federal gas tax dollars that are returned to our region.

The 2024-29 Transportation Improvement Program (TIP) is a clearinghouse of approved transportation projects throughout the region that are scheduled for construction or implementation over a six-year period. The TIP is fiscally constrained, meaning that funding for its projects is reasonably expected to be available.

These projects are funded with various combinations of federal, state, and local funds, including federal grants awarded and managed through CDTC's project selection process. 

All federal funding expenditures in the TIP have been approved by CDTC and are certified as consistent with the policies and long-term goals identified in the Transportation 2040 plan.

Transportation funding in Washington state is complex. For every paving job, bicycle lane or bridge widening, the money probably comes from a different tax or fee.  For more information, the Transportation Resource Manual published by the Joint Transportation Committee of the Washington Legislature provides a complete explanation of how the public funds transportation in our state.
