Five weeks after the I-24 landslide in Whites Creek, all the soil has been removed and work in the eastbound lanes continues to build the rock buttress to stabilize the slope.
On Tuesday, News 2 saw several crews driving up the slope with solid grade rock to help build the buttress.
“We are currently focused on building the rock buttress,” said Shay Deason, TDOT Regional Operations Engineer. “Thirty-thousand tons have been originally been put in and we have another 35,000 tons we estimate to go back.”
Deason said crews are working to build the buttress from the base to the top of the slope.
Contractors are working six days a week, 12 hours a day to finish up the work.
Deason said the height of the slope is a challenge.
“Right now, the rock buttress is like a giant scotch that we’re putting it, it holds the soil above in place,” he said. “The tricky part is getting all the rock up to the top of the slope. It’s slow in progress because we got 75 feet in height. It’s hard to get trucks up and down at this point.”
Deason said the excavated soil will allow water to drain freely to help prevent a future collapse of the hillside.
He added because the work site is in a rural area, nearby residents won’t be impacted by the construction and sound will be contained to the interstate itself.
Deason added the soil has been transported to a state-owned site in West Nashville.
The project’s updated timeline is set to finish around late summer.
At that point, the eastbound lanes will be shifted back to their original position.
