TDOT asks for construction review

I-40 at Mt. Juliet's MM 226 -
The Tennessee Department of Transportation has asked the contractor behind the widening of Interstate 40 at Mt. Juliet Road to address ponding issues following several wet-weather crashes.

Citing the crashes, state and local law enforcement had asked TDOT to review the corridor, near mile marker 226.

The analysis included crash data, roadway design plans and an additional road survey known as Light Detection and Ranging (LiDAR).

In a news release issued Friday afternoon, TDOT noted the section of I-40 was recently widened from west of Mt. Juliet Road to east of Highway 109 as part of a design-build contract with Lane Construction Corporation. Design-build is a project delivery method that allows a single contractor to provide design and construction services.

"Based on the initial data analysis," the TDOT release reads, "it is believed that the design-build team did not adequately address storm water runoff or the spread of storm water into lanes of travel.

Additionally, TDOT believes the project was not constructed adequately to provide for appropriate water runoff.

"As a result of the findings, TDOT has asked the design-builder for an action plan to address these issues."

To help address immediate concerns, message boards will be posted to warn motorists of potential ponding of water during inclement weather.

A dedicated TDOT HELP unit will also be on-site during weather events to shift traffic as needed.
