Winning bid shaves a year of I-440 rebuild

Tennessee Department of Transportation (TDOT) has awarded a US$152.9m contract that will save a year on the original schedule for rebuilding the I-440 while avoiding total road closures.

The low bid was submitted by Kiewit Infrastructure South. Its winning design-build proposal involves completing the design and construction of the project in less than two years.

“Using the design-build contracting method allowed us to explore every available option to deliver this large, complicated project,” said TDOT commissioner John Schroer said. “We believe the process led to several innovative concepts, and the winning proposal saved more than a year of construction time.”

Over the next three to four months, Kiewit will work with TDOT to complete the final design of the I-440 reconstruction project. The initial schedule of work involves starting work on site in fall this year, beginning with installation of a fiber-optic network and new lighting, construction of seven noise walls, and completion of two small projects to alleviate congestion.

Heavy construction activities, which will start in early 2019, include replacement of the concrete pavement, widening of the roadway and removal of the center raised median.

In spring 2019, Kiewit will begin 24 hour operations, six to seven days a week, including heavy night-time work. Work on the I-440 bridge over I-65 is scheduled to begin in fall 2019.

Completion is targeted for August 2020.
