A vehicle went off the ramp from Pilot Knob Road to westbound 494 and landed in the ditch. Ramps and bridges have occasional slick spots.
Look for another motorist in the ditch on the ramp from westbound 694 to southbound 35E.
In the far suburbs, look for slick spots, too. Authorities are responding to a rollover crash on Bass Lake Road at County Road 116 in Corcoran.
