The Tennessee Department of Transportation will be testing the fog zone alert system on I-75 in Bradley County on Sunday morning, April 29, 2018 beginning at 9:00 a.m. EDT.

The test should last approximately two hours.

The weather predicted for Sunday should make the testing easier for those involved, since after the many recent days of ray we've had, both Saturday and Sunday are expected to be sunny and clear.

Drivers should be aware of the testing and workers that could be along the highway.
