This road took a ride instead of being part of one. What you're seeing is a ~2x4 foot slab the opposite side of the road washed onto the edge of the other lane.
Today marked the 13th mountain bike workout that I've had scheduled this season (not counting races) and the 8th that has either been straight up rained out or the trails have been way too muddy. I was supposed to help teach the beginner group at the Midwest Women's Moutain Bike Clinic today, but it was cancelled due to heavy thunderstorms and flash floods. The weather was okay in the afternoon, but I was relegated to the road once again.
