Project Description

PLAN Go, Tennessee's first 25-Year Long Range Transportation Plan (LRTP) was completed in 2005. The Plan, which was the result of an extensive public planning process throughout the State, consists of three principle elements:

  • 25-Year Vision Plan, which broadly defines how Tennessee will respond to the trends and challenges facing the transportation system,
  • 10-Year Strategic Investments Program (SIP), which identifies critical investments that warrant accelerated funding or special attention over the next 10 years, and a
  • 3-Year Project Evaluation System (PES), which guides the selection of the 3-year program of projects giving state and local leaders a broader view of projects under development.

Of these elements, the Strategic Investments Program (SIP) identifies proposed spending priorities and policy initiatives that will address many of Tennessee's transportation needs and help implement the LRTP over the next ten years. The SIP established three interrelated core investment initiatives: congestion relief, transportation choices, and key corridors. A study of the I-40/81 corridor was completed in early 2009.

The Interstate 75 Corridor from Chattanooga to the Kentucky State Line was identified through the LRTP planning effort in the SIP as a corridor that is significant to Tennessee's economic development, particularly with regard to freight movement. The purpose of the I-75 Corridor Feasibility Study is to obtain a more detailed understanding of the deficiencies of the corridor and then develop corridor level multi-modal solutions to address these deficiencies.

The study area for the I-75 Corridor Feasibility Study extends from the Georgia State Line in Chattanooga to the Kentucky State Line, a distance of approximately 160 miles. The corridor includes I-75, parallel Class I railroads, and parallel major arterial routes. The corridor traverses seven counties, three Rural Planning Organization (RPO) areas, and three Metropolitan Planning Organization (MPO) areas. Cities along the route such as Chattanooga, Cleveland, Athens, and Knoxville, depend on this corridor for commerce, tourism, and daily commuting.

The study's final product is a prioritized listing of multi-modal projects that can be considered by TDOT for the Department's Transportation Improvement Program (TIP), as well as by MPO's and RPO's for their respective local and regional planning programs. Identified multi-modal solutions will address capacity, operations and maintenance, safety, freight movement, intermodal connections, and economic access issues along the study corridor.

The work plan for the development of the I-75 Corridor Feasibility Study generally follows the steps shown below:

  • System Inventory and Data Collection
  • Assessment of the Deficiencies
  • Development of Potential Solutions
  • Project Prioritization
