Is There a Sinkhole Forming Under a Duluth Street? [VIDEO]

On my way home from work this afternoon, I happened to discover a bunch of cones on the road that were blocking off more than just a bad pothole. I decided to investigate, and while it may not be a full-on house-eating sinkhole, the caving pavement reveals a hole that is away more than just a simple pothole that needs patching.

So, what is it? I couldn't tell how deep the deepest part of the hole was, but it looked like it was at least a foot in the areas I could see. From the looks of it, there has been previous work done in this same location. Maybe something was left unfilled after a previous repair, or maybe something washed away or shifted with the spring weather. In any case, be aware if you're traveling 10th Avenue West in the downhill lane.
