BELL Construction is proud to announce that the Tennessee Department of Transportation (TDOT) has awarded us the $54.3 Design-Build contract for the new I-65 Buckner Road interchange in Spring Hill.

I-65 Buckner Road – Project Information

The project includes the extension of Buckner Road from Buckner Lane to Lewisburg Pike across I-65 with a Diverging Diamond Interchange (DDI), also called a double crossover diamond interchange (DCD). To show local drivers who may be unfamiliar with this traffic arrangement how a DDI works, TDOT has prepared this video.


“The community of Spring Hill is growing and will only continue to do so,” said Jeremy Mitchell, BELL Construction’s Executive Vice President, Transportation Operations. “As we all know, with growth comes increased traffic. The Diverging Diamond is a newer concept for our area, but it has been successfully deployed to help mitigate traffic issues in various parts of the world for almost 50 years. We look forward to working with Neel-Schaffer and TDOT to bring this project to Middle Tennessee.”

As the Design-Builder for this project, we will partner with Neel-Schaffer to develop final design plans and complete right-of-way acquisition, permit approvals, utility relocation, and construction. Our fast-track approach will allow us to finish the project ahead of the project’s 2025 deadline.

The anticipated schedule for this project is as follows:

  • January 2021 – Fall 2022  Project design
  • Spring 2021 – Fall 2022  Right-of-way acquisition, permit approvals, and utility relocations
  • Spring 2022 – Spring 2023  Construction

“The City of Spring Hill’s diligence in securing this competitive grant put this interchange on the fast track,” said TDOT Commissioner Clay Bright. “TDOT has an aggressive schedule to meet, but the Design-Build contracting method allows us to tap into the innovation of the private industry and deliver the project in a much shorter timeframe compared to traditional design-bid-build projects.”
