Colorado State Patrol say a sleepy truck driver may be to blame for a diesel spill in Cameo this morning.
A semi driving on I-70 drove off the highway through a brush then over a frontage road.
It finally landed on its side, but diesel gas from the truck started to leak out, almost getting into the nearby Colorado river.
The truck is still sitting on its side next to exit 46 on the westbound side of the interstate, and the towing company on-scene says it could take all day to get the truck out of there.
The driver was not injured.
