What is a Transportation Improvement Program?

A Transportation Improvement Program (or TIP) is a comprehensive four-year program of regional transportation investments of all types: maintenance and preservation of existing roads, construction of new roads, public transit improvements, bicycle and pedestrian facilities, bridge replacement projects, etc. These projects come from cities, towns, and agencies throughout Spokane County. All transportation projects that are regionally significant or receiving federal funding are required to be included the TIP. SRTC updates the TIP annually and after it is approved it becomes part of the Washington State Transportation Improvement Program.

Key purposes of the TIP are to:

    • Demonstrate fiscal constraint for the projects contained in the plan (meaning there is adequate funding available for the planned projects)
    • Demonstrate that the projects meet conformity with state air quality standards (projects aim to improve air quality or maintain it)
    • Identify other planned transportation projects adopted in local six-year TIPS (bring together projects from the local level into one, 4-year program


The 2024-2027 TIP was approved by the SRTC Board of Directors on 10.12.2023. Click the image to the right to access the full TIP document and click the icon below to access an interactive map showing the projects in the TIP.
