Chattanooga’s I-75/I-24 Interchange Faces Major Roadwork

Chattanooga, August 3, 2025

News Summary

Chattanooga is set for significant roadwork at the I-75/I-24 interchange, beginning on August 3 and continuing through August 5, affecting traffic flow. The construction involves widening ramps from two to three lanes but will reduce traffic to one lane during nightly hours. Motorists are encouraged to consider alternate routes to avoid delays and to stay informed through the Tennessee Department of Transportation’s resources.

Chattanooga is preparing for significant road construction that will affect traffic at the I-75/I-24 interchange over the next two weekends. The construction will begin on Sunday, August 3, 2025, and continue through Tuesday, August 5, 2025. These activities are part of Phase 2 of a project aimed at widening and improving the interchange, which is crucial for regional traffic flow.

The upcoming construction phase will involve moving traffic to its final alignment on the interstate ramps at the interchange. The existing ramps will be widened from two lanes to three lanes, which is expected to better accommodate the growing volume of vehicles. However, this improvement comes with some anticipated challenges, as traffic will be reduced to one lane on each ramp and on I-24 West during the nightly construction hours, which will run from 9:00 PM to 6:00 AM.

For the duration of the construction, I-24 West will maintain its current three-lane configuration from the Moore Road exit ramp through the end of the project limits, albeit with some restrictions. One through-lane on I-24 West will end near the Spring Creek Road bridge, with the remaining two lanes becoming exit lanes to Moore Road. The remaining lanes on I-24 West are expected to reopen by the end of August 2025.

Motorists are advised to consider alternate routes and to minimize travel through the affected area, as delays are likely. The Tennessee Department of Transportation (TDOT) is encouraging all drivers to adhere to posted signs and to stay alert for changing traffic conditions. In particular, they emphasize the importance of checking travel conditions and utilizing available motorist information tools prior to departure.

The ongoing construction is part of a larger project that began in June 2023, with a projected cost of nearly $161 million. While the I-24 segment of the project is reported to be on schedule to complete the new lanes and ramps by fall 2025, delays on the I-75 portion may delay completion into spring 2026 due to required coordination with CSX railroad for bridge construction. Travelers should also be aware that other ongoing road construction projects in the vicinity may further contribute to delays.

Drivers should also take note of Tennessee’s Move Over Law, which imposes penalties for violations that could include up to 30 days in jail and a maximum fine of $500. Compliance with this law is essential for ensuring the safety of both motorists and construction crews.

For real-time updates on traffic conditions, travelers can access the TDOT SmartWay Map or contact 511 for statewide travel information.
