(Formerly Southwest Dickson Bypass)

Project Timeline

Transportation projects are developed in four phases:

  1. Planning and Environmental
  2. Design
  3. Right-of-Way Acquisition
  4. Construction

The project is currently in the Planning and Environmental stage. The following is a timeline of the events concerning this project:

April 2004:

  • TDOT developed an Advanced Planning Report (APR). This document evaluated three bypass options around Dickson.

November 2004:

  • TDOT held a public meeting to discuss the APR. In general, there was strong public support for the bypass, however, issues were raised concerning the project termini.
  • The questions raised at the public meeting led the City of Dickson and Dickson County to conduct a land use study which led to the development of a Transportation Planning Report (TPR).

December 2006:

  • A Transportation Planning Report (TPR) was completed. This report discussed preliminary purpose, needs, and goals of a Dickson bypass.
  • It was determined that a bypass was needed to improve mobility west and south of Dickson, provide additional access to I-40, relieve traffic congestion in Dickson’s urban core, support economic development, and increase accessibility to Dickson’s airport and industrial park.

July 2007:

  • TDOT began preparing an Environmental Impact Statement (EIS) to determine the impacts that a bypass would have to the natural and human environment.
  • The EIS will evaluate the context and intensity of the impacts to determine the significance of those impacts.

September 2007:

  • TDOT met with public officials in Dickson, TN, to summarize the project’s history and present a plan to move forward.

November 6, 2007

  • A public meeting was held to discuss the purpose and need. The meeting was held at Dickson County High School.

June 26, 2008:

  • A public meeting was held to obtain input for the location of project alternatives. The meeting was held at Dickson County High School.


  • Finalized alternatives to be carried forward in the EIS
  • Began environmental technical studies and conceptual engineering


  • Completed environmental technical studies and conceptual engineering
  • Began Draft Environmental Impact Statement (DEIS)


  • Complete DEIS
  • Federal and state agencies approve DEIS
  • DEIS made available to the public
  • Hold Public Hearing


  • TDOT selects the Traffic System Management (TSM) alternative
  • Coordinate with State and Federal agencies regarding the selected TSM alternative
  • Prepare the Final Environmental Impact Statement (FEIS)


  • Receive FHWA approval of Environmental Document
