Tennessee officials outline plans for I-24 choice lanes to address congestion

The Tennessee Department of Transportation (TDOT) held a public meeting on May 24, 2025, to discuss the I-24 Southeast Choice Lanes project. The meeting focused on the methodology for setting user fees, project scope, and community concerns regarding traffic management and safety.

The discussion began with an explanation of the dynamic pricing model that will be used for the choice lanes. This model is designed to regulate the number of vehicles using the lanes, ensuring they function effectively. If the pricing is not set correctly, it could lead to violations of minimum speed requirements outlined in the developer's contract. However, officials emphasized that the existing four general-purpose lanes will remain available for those who choose not to pay the fee.

Regarding the project's scale, it was clarified that not all 26 miles of the corridor will be constructed simultaneously. Instead, TDOT plans to phase the project, potentially starting with a smaller segment of 12 to 14 miles. This approach aims to foster competition among developers and ensure the project is appropriately sized for market response.

The I-24 Southeast Corridor was selected for the choice lanes due to its status as the most congested area in Tennessee, based on an extensive study of traffic conditions across the state. Officials expressed a desire to expand choice lanes throughout Tennessee in the future, but noted that this corridor was the most pressing starting point.

Concerns about traffic incidents and emergency responses were also addressed. While the choice lanes are intended to remain free-flowing, officials indicated that they would not be used to divert traffic during emergencies. However, first responders will have access to these lanes to perform their duties.

The meeting also covered specific access points along the corridor. While the Rocky Fork interchange is not currently proposed as an access point, feedback from the community is welcomed. Additionally, questions about variable speed limits and the conversion of existing high-occupancy vehicle (HOV) lanes were discussed, with officials noting that federal regulations prevent changes to HOV lanes.

In conclusion, the meeting provided a comprehensive overview of the I-24 Southeast Choice Lanes project, addressing community concerns and outlining the next steps in the planning process. TDOT aims to keep the public informed and engaged as the project progresses.
