Concrete repairs set for next several weekends on I-75 between Shallowford Road and Ooltewah exits

Works crews to be active from 9 p.m. to 6 a.m. with lane closures

Nighttime work over the next several weekends in a state concrete and bridge repair project on Interstate 75 means contract crews must close some lanes in both directions on a 6-mile stretch between Shallowford Road and a little north of Ooltewah.

The work includes repairs to damaged concrete slabs, bridges and the installation of new pavement markings, according to a news release from the Tennessee Department of Transportation.

After 9 p.m. over the next few weekends, motorists will encounter closed lanes and potential backups surrounding the sections being repaired, TDOT spokeswoman Rae-Anne Bradley said in Thursday's release.

"During this work, the contractor will remove damaged concrete slabs and re-pour them with new concrete, which will require several hours to develop enough strength to carry traffic," Bradley said.
