A tanker truck rollover led to the partial closure of U.S. 22 east of Cadiz earlier Tuesday night.
The 2,000-gallon tanker was full of oil, which spilled when the tank broke.
Several agencies responded to the scene, including Jefferson County hazmat crews.
There is a pond down the hill from the crash site that some cattle use as drinking water. The property owner has been notified about the spill. No injuries were reported.
