Even if I have been taking photos for about six months in this place, I never saw this angle. Right at the middle of the overpass bridge there is ramp that goes down to almost the street level, where there are the gates where people press their electronic bus cards before jumping on the busses. Some people walk fast. Some walk slow. This evening I did not see people who were in a rush. It was good moment to get down to the floor level, focus near the tip of the lens and let all the rest blur. I used my dx kit lens, at 24mm. Nothing fancy.
