Transportation Improvement Program (TIP) List

The Statewide Transportation Improvement Program (STIP) is a Connecticut Department of Transportation (CTDOT) four-year planning document that lists all projects expected to be funded in those identified four years with Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) participation. The STIP is multi-modal and includes investments in various modes, such as transit, highways, and bicycle facilities. The STIP is the venue for implementing the goals and objectives identified in regional and State transportation plans. Regionally, this document is called the Transportation Improvement Program (TIP) and includes all projects funded during the four-year subject time frame, both state and federally funded.

The federal transportation funding bill requires the TIP to be developed at least every four years. To cover a period of four years, the TIP must be financially constrained and demonstrate that the projects are fundable through known funding sources. The TIP must also reflect air quality changes due to the scheduled transportation projects. These projects must be consistent with the Metropolitan Transportation Plan, and a public involvement process must meet Environmental Justice and Title IV requirements.

How do the STIP and TIP affect me?

The STIP and TIP are important documents that represent the direction of transportation capital improvements over a four-year period. Transportation infrastructure is vital to our modern world and includes roads and bridges, public transportation like buses and trains, as well as sidewalks, multi-use paths, and ferries. The process of adoption of these documents is an opportunity for our constituents to voice their interests and concerns for our transportation future.
