Thursday, April 25, 2019 | 12:58pm

CHATTANOOGA, Tenn. – The Tennessee Department of Transportation, in conjunction with the Tennessee Highway Patrol and contract crews, will conduct fog zone scenario testing on I-75 North and South in Bradley and McMinn counties on Sunday, April 28, 2019 between the hours of 8:00 a.m. and 10:00 a.m. EDT. The fog zone area encompasses I-75 from mile marker 27 in Bradley County to mile marker 44 in McMinn County.

During this time period, TDOT and THP may implement closures of interstate on-ramps throughout the fog zone area to perform fog zone scenario testing activities on dynamic message signs, changeable speed limit signs, swing gates and fog detection systems. Crews will work along I‑75 in both directions at the on-ramps at exits 27, 33, 36 and 42.

This work is weather dependent. Should inclement weather or unforeseen circumstances delay the testing, it will be rescheduled to take place at a later date.
