Extreme drought is causing damage to the Natchez Trace Parkway, warn National Park Service officials.
They cautioned drivers Monday about severe cracking and movement of the road surface along the Mississippi portion of the parkway.
This damage is especially dangerous for those on motorcycles.
Officials say the movement is due to shrinkage of the underlying soils, and the issue will worsen as the drought continues.
The problem is not as prevalent on the Alabama or Tennessee sections of the parkway.
Drivers are urged to exercise caution.
