TDOT plans to make improvements along I-440, from I-40 to I-24 in Davidson County. The proposed project includes removing substandard pavement and providing three lanes of travel in each direction along the entire 7.6-mile corridor.

I-440 is currently a concrete surface. Due to age, weather, and traffic demands, the concrete is severely deteriorated and requires replacement. Recent spot paving provided a temporary surface improvement, but will not stop the existing roadway from crumbling underneath.

The contract was awarded in August 2018. The work will be completed using traditional methods, allowing I-440 to remain open during construction with lane closures in place for the duration of the project. The estimated completion date is August 2020.

Some preliminary work will start in November 2018, including noise wall improvements, fiber relocation, lighting, and ramp queue projects. Any work requiring extensive lane closures will start in early 2019.

No, I-440 will remain open, but lane closures will be in place for the duration of the project. During the day, at least two lanes will remain open in each direction between 5 a.m. and 9 p.m. At night, at least one lane will remain open in each direction between 9 p.m. and 5 a.m.

NOTE: This does not include the widening of I-440 over I-65, which will require the closure of the interchange for two weekends.

Predominantly, all ramps will remain open, but auxiliary lanes will be closed, creating yield conditions at entrance/exit ramps along the corridor.

Ramp closures are expected as crews move to different parts of the project and make improvements, including concrete repairs, to interchanges; however, interchanges will not be closed concurrently.

Yes, the contractor will be allowed to work 24 hours a day and 7 days a week to expedite construction; however, noise walls must be completed prior to beginning overnight work.

Yes, the work zone is expected to be noisy. Noise impacts can occur on any project involving the construction of a highway due to typical construction activity; however, the reconstruction of I-440 will require contract crews to break up 10-inch thick concrete throughout the corridor. The equipment needed to perform this work and the work itself will be loud. Prior to the work, TDOT will provide construction schedules to give local communities advance notice of the expected additional noise in specific areas of the corridor.

Adjacent routes may experience increased traffic volumes from motorists seeking alternate routes. TDOT is reviewing innovative ways to reduce congestion on I-440, including aggressive incident management and coordination with local agencies.

Yes, additional lanes will be constructed to provide three travel lanes (minimum) in each direction.

Yes, the inside grassy median will be removed to provide an additional third lane of travel in each direction.  

Yes, three bridges along I-440 (Lealand Lane, Craig Avenue, and I-65) will be widened to add one travel lane in each direction.

Separate from the traditional construction, contract crews will be allowed a maximum of two full weekends to close a section of I-440 and I-65 in order to widen the overpass bridges at the I-440/I-65 interchange. Closure dates will be determined by the contractor and announced by TDOT prior to their occurrence. Any weekend closures would occur from Friday at 9:00 p.m. to Monday at 5:00 a.m.

Yes, existing damaged or deteriorated entrance/exit ramp sections along I-440 will be repaired.

Yes, the eastbound off-ramp at Murphy Road and the westbound off-ramp at 21st Avenue/Hillsboro Road will be upgraded. Upgrades include ramp widening, raised concrete islands, traffic signal improvements, signing, striping, crosswalks and handicap ramps.

Yes, noise wall repairs will be performed at multiple locations along I-440. Also, new noise barriers will be constructed at locations identified during the project’s noise study. The new noise wall locations are east of Marlborough Avenue, west of Woodlawn Drive, near Lealand and Craig Avenue, and near Lyle Lane bridge. Noise walls will be required to be constructed prior to allowing night work.

Yes, all lighting along I-440 will be replaced, excluding the high-mast lighting within the I-65 interchange.

Yes, landscaping will be provided at seven interchanges along I-440 including I-40, West End Ave, Murphy Avenue, Hillsboro Pike, I-65, Nolensville Pike and I-24. The landscaping will consist of new trees, shrubs, grasses and mulched beds.

Yes, drainage repairs and additional drainage are part of the project.

Kiewit Infrastructure South Co. was awarded the contract to reconstruct I-440 using traditional construction at a cost of $152.9 million.

Using the Design-Build project delivery method, TDOT was able to consider several options for the reconstruction of I-440, including traditional construction (which allows the interstate to remain open) and segmented closures (which allow all lanes of the interstate to be closed during construction of a specific segment).

TDOT reviewed the contractor-submitted proposals, evaluating plans, schedules, costs, and motorist impacts. The winning proposal will complete the work using traditional construction and will reduce the originally projected construction timeline by more than a year at a cost of $152.9 million, the lowest bid received.

Design-Build is an alternative to the traditional Design-Bid-Build project delivery method. Design-Build combines various portions of the design and construction phases into a single contract, whereas Design-Bid-Build separates design and construction into separate contracts and separate work.

Design-Build can provide a more unified flow of work from conception to completion by allowing the contractor to bring innovative solutions to improve project delivery time, reduce project costs, and reduce impacts to the public.

TDOT is utilizing the design-build concept to expedite project delivery and streamline design processes for the I-440 Reconstruction Project.
