BNA Rental Car Traffic Pattern Changes Begin Sept. 30

As of June 18, 2025, Nashville International Airport (BNA) has confirmed that drivers leaving the rental car facility and the valet pickup area will be rerouted to a newly signalized intersection starting Sept. 30. The change is tied to the airport’s ongoing construction program, which includes a large consolidated rental car building and a separate parking garage. The new signs and lane markings have already gone up, but the active switch will not happen until the last day of September.

What will change on Sept. 30

The new traffic signal sits at the exit point of the rental car facility’s current construction zone. Once the new pattern takes effect, drivers coming out of the rental car return lanes and the valet service area will be directed straight into that signalized intersection. From there, a protected left-turn movement will connect drivers to I-40 West, I-40 East, and Donelson Pike via Exit 216B.

The signal is designed to make the exit safer and more predictable. A protected left turn gives drivers their own dedicated phase, so they do not have to judge gaps in fast-moving traffic. For visitors who are unfamiliar with the airport, this reduces the chance of a wrong turn into a construction lane or a last-minute merge.

The construction project behind the change

This is not a simple lane reconfiguration. The new intersection is part of a much larger project that will eventually replace the airport’s older rental car setup. BNA is building a six-story rental car facility with approximately 3.5 million square feet of space. That building is designed to handle up to 4,700 vehicles at a time, with 3,500 spaces set aside as ready-return stalls for customers dropping off rental cars. The remaining 1,200 spaces will be used for staging and storage, giving rental companies enough room to move vehicles through cleaning and maintenance without crowding the public exit areas.

A new parking garage is also part of the project. That garage will add 3,000 parking spaces to the airport’s overall supply. While it will sit close to the rental car facility, it is planned as a separate operation, with its own entrance and internal circulation.

Why the exit is changing before the building opens

BNA is activating portions of the road network ahead of the facility’s full opening. That is a common approach for large airport projects: getting intersections, signals, and lane markings into place first gives contractors room to work and gives drivers time to adjust before the main building opens.

The Sept. 30 switch also avoids making changes during the busier fall travel season. Late September is a quieter window between summer travel and the Thanksgiving rush. That gives the airport a few months to observe traffic flow, fine-tune signal timing, and correct any signage problems before the holiday period adds more volume.

What drivers need to know

For anyone using the rental car center or valet service after Sept. 30, the route will look noticeably different. The most important points are:

• Exit 216B is the target. The new signalized intersection feeds directly into the ramps for I-40 West, I-40 East, and Donelson Pike. Missing the turn may send drivers back around the airport loop.
• Navigation apps may be out of date. Temporary construction layouts are not always reflected in GPS databases. Drivers should follow the physical signs for “Rental Car Return,” “Valet,” and “Airport Exit” rather than relying only on a phone map.
• Allow extra time. The surrounding area is still an active work zone. Crews may be moving barriers, painting markings, or shifting lanes at different stages of the project.
• Stay alert near the signal. The intersection is new, and drivers will be seeing it for the first time. Slowing down and obeying the signal phases is the safest way to navigate through.

What this means for airport travelers

The rental car facility and parking garage are part of BNA’s broader expansion program, which has been underway for several years. The airport has seen strong passenger growth, and the current construction is aimed at updating facilities that were built when travel volumes were much smaller.

The consolidated rental car building is one of the largest pieces of that program still under construction. When it is fully operational, it will bring rental car check-in, vehicle return, and pick-up operations into one integrated space. That should reduce the amount of time travelers spend shuttling between separate locations and help keep rental car traffic out of the main terminal loop.

BNA has not announced a full opening date for the rental car facility, but the Sept. 30 traffic signal activation is a clear sign that the project is moving into its final stages. Over the next few months, drivers should expect more visible changes on the eastern side of the airport, including additional lane shifts and possible short-term closures.

For now, the airport’s message is simple: be ready for a different exit pattern after Sept. 30, watch the new signs carefully, and give yourself a little extra time if you are heading to the rental car center or valet pickup during the transition.
