Avoiding Highway 231 in Daviess County is advisable, for the time being, now that a semi carrying molten aluminum has overturned.

The Kentucky Transportation Cabinet is reporting that U.S. Highway 231 North is blocked at the 12 mile marker.

Daviess County Sheriff's Office and the Daviess County Fire Department, along with volunteer fire crews are on the scene.

The truck spilled a crucible of molten aluminum when it crashed.

All four lanes of 231 are closed at this site and the Natcher Bridge is, as well.

The KYTC is estimating a four-hour closure in order for crews to clean up the mess.
