The Kane County sheriff says closed the road late Saturday because 100 gallons of diesel fuel has spilled on the road and into a ditch.
The fuel was leaking from a semi-truck that had crashed at about 6 p.m. when a car made a U-turn, causing the semi to swerve in an effort to avoid the car. The semi wound up going into a ditch on the east side of Route 47, and then back onto the road, coming to rest on the west shoulder.
A gas tank ruptured on the semi and caused the diesel fuel to leak.
No one was injured in the crash.
