Drivers traveling near the I-75 at the I-24 interchange in Hamilton County should be aware of upcoming road construction activities impacting traffic. As part of Phase 2 (the second of two projects) to widen and improve the I-75 at I-24 interchange, Tennessee Department of Transportation (TDOT) contract crews will begin moving traffic to its final alignment on the interstate ramps at the split over the next two weekends.

- I-75 South to I-24 West
- • I-75 North to I-24 West
The new configuration will increase capacity from two lanes to three lanes on both interstate ramps. Between 9:00 pm and 6:00 am each night, traffic will be reduced to one lane on each ramp and on I-24 West to facilitate this work.
Although these ramps will be widened to three lanes, I-24 West will remain in its current three-lane configuration from the Moore Road exit ramp through the end of the project limits. To accommodate the reduction from six lanes to three lanes in this area, one through-lane will end near the Spring Creek Road bridge, while the remaining two lanes will be dedicated exit lanes to Moore Road. The remainder of lanes on I-24 West should be opened by the end of August…
