For reference, here is a photo of the brooklyn bridge lanes:



It is a very narrow lane for 2 way traffic. Bikes are expected to stay on their side, peds on theirs. It is clearly marked. Clueless peds with cameras have nearly caused me to crash many times. It was ONLY the fact that I was very alert that saved both of us. I suspect from this story that OP, even if he is a cyclist, is just a clueless a ped as the others. Because this lane is so iffy, I switched to the Manhattan Bridge which physically separates peds and bikes and has a much wider lane.
