ROCKBRIDGE COUNTY, Va. - UPDATE
All lanes are now open.
Hazardous material removal crews are cleaning up after a tractor-trailer that's causing a traffic issue on I-81.
The southbound left lane is blocked at mile marker 204 in Rockbridge County, between the Raphine and Fairfield exits.
There is a 2-mile backup, as of 8:20 a.m. There is also congestion on Route 11.
The truck had to brake suddenly, which caused the load to shift and spill. The spill was mostly contained inside the trailer, with a small amount leaking onto the ground.
The truck was hauling organic peroxide and sodium hydroxide.
Cleanup is expected to continue through late Friday morning.
