2019 Transportation Improvement Inventory

The Environment and Infrastructure Division has completed and posted its 2019 Transportation Improvement Inventory (TII) to the Chester County Planning Commission’s website. In addition to the complete TII document, the website offers project lists by municipality, as well as legislative district. The TII is a comprehensive record of known transportation needs within Chester County. It includes proposed roadway, bridge, bicycle/pedestrian, and transit projects that have been recommended to the CCPC by municipalities and other stakeholders over time.

The TII serves as Chester County’s prioritized input to the Delaware Valley Regional Planning Commission (DVRPC), which serves as the Metropolitan Planning Organization charged with the development of the Southeastern Pennsylvania region’s federally required Transportation Improvement Program (TIP).  The region’s TIP then becomes part of the Pennsylvania Department of Transportation’s (PennDOT) Twelve Year Program for transportation funding.

The TII is also used internally to track the status, identify next steps, and guide implementation of transportation projects. This includes identifying alternate funding sources such as the Multimodal Transportation Fund, which was created by Act 89 and offered twice per year – once by PennDOT, and once by the PA Department of Community and Economic Development (DCED). Although TII listings do not represent programming or provide direct funding, they do recognize and emphasize the need for additional technical and financial resources.

The 2019 TII includes 532 projects totaling an estimated $4.42 Billion, while the previous 2017 TII had 508 projects totaling $4.25 Billion.

New this year for the TII, the Environment & Infrastructure Division is replacing the static maps of projects produced in previous TII documents with an interactive online map. This new format allows the projects to be shown better in their context, and include more specific project details such as sponsor municipality, project status, and estimated costs.


We encourage any feedback that you would like to offer toward improvement of the TII document and/or the online map. For any feedback or questions, please reach out to the Transportation Planner managing the TII for the Planning Commission and the creator of the online map, Eric Quinn.
