I-40 Flood Wall Project
I-40 highway rebuilds to withstand 500-year flood after 2024 storm.
In brief
I-40 highway rebuilds to withstand 500-year flood after 2024 storm. I-40 in Tennessee and North Carolina is being rebuilt with a 800,000-yard concrete wall to prevent future flooding after Hurricane Helene damaged it in 2024. Originally reported by The Drive.
I-40 damaged by 2024 storm
Hurricane Helene washed portions of Interstate 40 on the Tennessee/North Carolina border into the Pigeon River in 2024.
Rebuilding with flood defenses
The project uses 800,000 yards of roller-compacted concrete to prevent future flooding after Hurricane Helene.
Additional flood protection
An interlocking pipe pile system with 400,000 linear feet of 36-inch steel pipe forms the first line of defense against floodwaters.
Temporary infrastructure built
North Carolina built a temporary quarry and concrete-mixing plants to supply materials for the 800,000-yard concrete wall.
