This is a heavily-cycled link between South Philly and Port Fishington. Columbus is not a bike-friendly alternative and 5th Street has Belgian block and a major highway junction. 4th Street could also be implemented as a north-south adjunct. The 3rd Street route links to the Moyamensing bike lane and could utilize Thompson (Girard is problematic) to connect with Frankford, another important cycleway. As this street has varying parking configurations, it would make a fantastic candidate for sharrows.
