All lanes are blocked on I-20 westbound after the road buckled beneath the HOV lane.

A DeKalb County Police spokesperson said an underground gas leak between Candler and Gresham on I-20 caused the defect in the road.

A GDOT spokesperson said all lanes were closed while crews are still assessing the damage.

11Alive Skytracker showed the shoulder of the road and the HOV lane buckled and cracked.
