Interstate 440Davidson County
The reconstruction of Interstate 440, from Interstate 40 to Interstate 24 in Davidson County, includes removing substandard pavement and providing three lanes of travel in each direction for approximately 7.6 miles. The project is also intended to address congestion and improve safety along the entire corridor.
Purpose and Need
Originally known as Four-Forty Parkway, I-440 was designed and constructed in the 1980s as an east-to-west southern loop around the city of Nashville to address urban congestion created by a trucking industry boom. Upon completion of the roadway in 1987, it was considered a limited-access highway, linking I-40 west of the city with I-65 and I-24 south of the city. The four-lane facility was built to accommodate up to 64,000 vehicles per day.
Today, traffic counts along the interstate connector average 100,000 vehicles per day. Much of the existing concrete road surface is in substandard condition and needs to be removed. An extensive pavement replacement project is needed to repair the facility. The planned improvements will also increase capacity and improve safety along the corridor.
The existing concrete roadway is primarily four lanes (two lanes in each direction), with the eastbound and westbound lanes separated by a grassy, elevated median and auxiliary lanes located near the interchanges. The new design calls for replacement of the deteriorated concrete pavement with asphalt and removal of the median to provide a facility with at least six lanes (three lanes in each direction) throughout the corridor.
In an effort to expedite project delivery, the I-440 construction 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.
On August 1, 2018, Kiewit Infrastructure South Co. was awarded the contract to reconstruct I-440 using traditional construction at a cost of $152.9 million. Traditional construction will allow the interstate to remain open with lane closures in place for the duration of the project. The estimated complete date is August 2020.
