Interstate 24, a portion of which has been closed for more than a month after a landslide, reopened Wednesday afternoon.

The Tennessee Department of Transportation reopened I-24 eastbound at mile marker 42 around 6 p.m. Wednesday, after more than two weeks of traffic backups due to the closure.

The Feb. 23 landslide caused approximately 50,000 cubic yards (about 5,000 dump trucks full, according to a TDOT engineer) to shift into the roadway, affecting a 3/4 mile length of the interstate.

The area was closed to travelers on a high-volume commute path between Clarksville and Nashville.

To help get things moving again, crews temporarily widened the interstate around the slide to accommodate two lanes of traffic while crews continue working on permanent slope repairs, TDOT has said.

So far, approximately 36,000 cubic yards of material has been removed from the slope in order to make the area safe for drivers, TDOT reported Wednesday.

The work is far from over, however, as crews need to build the hillside back up from bare rock to stabilize the material.

The permanent repairs include additional excavation of the slope and installation of a rock buttress behind a rock bench approximately 50 feet wide.

TDOT estimates this work will take months to complete.

And the price tag? The estimated cost for the permanent repairs and roadwork is ringing in at $8 million.
