From the Roane County Highway Department:

***Update*** We are in the process of closing Airport Road that goes up the mountain, with the recent storms and heavy rains that have come through, a large crack has opened up. This was discovered during one of the routine visits to check on the condition of the road. We hope this is a temporary closure, and we will continue to monitor and work on the situation. We thank you for your patience and understanding. We will update you through the process.***
