Interstate 440Davidson County
Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way (ROW), and Construction. In an effort to expedite project delivery, the I-440 rehabilitation will be completed under a Design-Build contract. The Design-Build project delivery method combines all or some portions of the design and construction phases of a project - including design, regulatory permit approvals, utility relocation, and construction – into a single contract.
The following is a reflection of various aspects of the project phases as they have occurred or will occur for the proposed I-440 improvements.

Timeline for Design-Build Project Delivery Method
On August 1, 2018, TDOT awarded the contract for the I-440 project to Kiewit Infrastructure South Co. for $152.9 million. The work will be completed in less than two years using traditional construction.
TDOT and the Design-Build team will work to finalize the design and project clearance to allow construction to begin as early as November 2018. The initial schedule of work is as follows.
- Fall 2018 – Begin installation of fiber optic network and new lighting, construction of seven noise walls, and completion of two small projects to alleviate congestion on the westbound Murphy Road exit ramp and the eastbound Hillsboro Road exit ramp
- Early 2019 – Begin heavy construction activities to replace concrete pavement, widen the roadway, and remove center raised median
- Spring 2019 – Begin 24-hour operations, 6 to 7 days/week, heavy nighttime work
- Fall 2019 – Begin work on I-440 bridge over I-65
- August 2020 – Estimated Completion Date
For the duration of the project, two lanes of I-440 will remain open during peak morning and afternoon travel times. Nighttime lane closures will be from 9:00 p.m. to 5:00 a.m. TDOT is also working closely with Metro Nashville Public Works to address signal timing and other issues on local streets in the project area, which are likely to see an increase in traffic once I-440 is under construction.
