I-440 Reconstruction Project Update

Work continues on the design-build project to reconstruct Interstate 440 in Nashville.  Last week, the Tennessee Department of Transportation released the Request for Proposals (RFP) for project.

Some of the key requirements of the RFP include:
· Replacing deteriorated concrete with asphalt.
· Adding capacity by in-stalling a third lane in each direction where currently there are only two, which will not require additional right-of-way.
· Eliminating the elevated grassy median throughout the corridor and replacing with a concrete median barrier wall.
· Widening the I-440 bridges over I-65 to three lanes in each direction.

Since the preliminary engineering for the project was funded by the IMPROVE Act last summer, TDOT engineers have been conducting geotechnical and subsurface utility investigations in order to complete an outline of the reconstruction project plans.

Now the qualifying design-build teams will spend the next five months completing the design plans, including a construction schedule for the project. TDOT will then review the plans and award the design-build contract, taking into account both the total cost and the construction time of each proposal.  Construction is expected to begin later this summer.

TDOT is currently estimating construction may take three years, but the exact time frame will depend on the submitted proposals.
