An Allied Waste Services truck spilled its load on National Road in front of Minute Carwash Thursday.
Wheeling Police say it happened around 11:40 a.m., when the driver of the truck slammed on his breaks, causing the sludge to spill up over the cab of the truck.
Workers from Allied Waste worked to clean the mess up off of the road.
Deputy Chief Marty Kimball says the sludge does not appear to be hazardous, but they are waiting on officials from the West Virginia EPA to come check it out. The EPA will then decide how the remaining sludge can be cleaned up.
Police say the driver had picked up the load at RG Steel and was headed to the landfill.
The driver of the truck told police that the landfill does not accept hazardous material.
Police ticketed the driver for an unsecured load.
Police have traffic moving in both directions, but drivers should expect delays. No injuries were reported.
They say clean up will likely take a few hours. Wheeling Police and Fire Department as well as West Virginia Department of Highways are all on scene.
