Didnt see the curb and 45 degree turn in the side walk in the early morning hours while riding my bike. I was checking for cars too but if the curb was painted I would have seen it in time to avoid it. Crashed at 18 mph flipped over handle bars and got some bad bruises and scraps - got lucky.
A. 54th St exit going southbound on 275. The sidewalk along 54th in middle of exit.
