Ah, early spring rides. The city repoured the concrete for this underpass during the winter and it opened this week so I went to check it out. Didn't occur to me that the pavement on both ends wouldn't be finished yet.
The water to the left is a 1.5 foot deep hole which I rode straight into. At the bottom is thick mud that my tire buried itself into so the bike stayed upright on its own when I got off.
