Would an extension from Locust to Winter St (near the Vine St Expressway viaduct) to Fairmount Park work? I was thinking of making a trail alongside between the CSX tracks and the Schuylkill River for walking and biking, and making that trail accessible via ramps through the tracks. Look up www.srdc.net to find out more about the projects. I liked the ideas of greening the Schuylkill, especially the Passyunk Crescent (although I think 63rd St, not 61st Street should be the retail corridor for that neighborhood). Check it out.
