A semi-truck on I-59 South at the 28-mile marker in Pearl River County just south of the Poplarville exit is on fire.
The semi-truck is loaded with propane bottles.
According to MHP, multiple first responders are on scene trying to control the fire and keep it from spreading into the wood line.
All traffic has been stopped due to exploding propane bottles.
MHP said that motorists should expect delays while traveling and find alternate routes.
