Hi Chefisaac, I live and bike in Philly. Are you looking for loops/trails, or just good ways to get around the city? From the BF bridge, I'd say the easiest way to get to South Philly is via Columbus and the rivertrail, or take 2nd or 4th going south. 2nd is closer, but has a weird curve/cobblestones to it by the society hill towers. 4th is great, just further inland. Any three of those are my preferred route to south philly from the BF bridge.
