Underpass on urban trail in Pueblo, Colorado, leading from downtown to the CSU/Pueblo campus. About as basic as you can get. I decided to walk rather than ride through this one after maneuvering around an abandoned shopping cart which you can see at the far end of the culvert. I had to walk over several crunchy things; I hope they were discarded water bottles.
