TDOT Contractor to Begin Concrete Rehabilitation and Bridge Repair Project Along I-75 in Chattanooga, Hamilton County

CHATTANOOGA, Tenn. – As part of the project to repair damaged concrete slabs, perform bridge repairs, and install new pavement markings, TDOT contract crews must implement lane closures on I-75 in both directions between mile marker 6.6 and mile marker 12.6. This work will occur nightly and over the next several weekends, with the exception of Memorial Day weekend.

The first section to be repaired is on I-75 South between mile marker 12.6 and mile marker 6.6. The repairs will begin at 9:00 p.m. EDT on Friday, May 6, 2022, and end by or before 6:00 a.m. EDT on Monday, May 9, 2022. The three left lanes will be closed during this work. Traffic will be reduced to two lanes through the work zone: the far-right lane and the shoulder. The open lanes will be striped accordingly. Traffic control will be in place and signage will be posted guiding motorists through the closure. Drivers should be prepared to expect delays and consider an alternate route during this time.

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. As soon as the concrete cures enough to pass strength tests, the contractor will reopen all lanes to traffic.
