Interstate 440 in Nashville is one step closer to becoming a smoother and less bumpy commute for drivers.
The Tennessee Department of Transportation announced Wednesday that it’s awarded the I-440 reconstruction project to Kiewit Infrastructure South Co. at a cost of $152.9 million.
TDOT said the project will not include any total closure of segments of I-440 and will take less than two years to complete.
“Using the design-build contracting method allowed us to explore every available option to deliver this large, complicated project,” 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, the company will work with TDOT to complete the final design of the project. Here’s an initial schedule:
- 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 – anticipated completion
TDOT said its taking every effort to reduce the impact on drivers. Two lanes of the roadway will remain open during peak morning and travel times. Nighttime lane closures will be 9 p.m. to 5 a.m.
