I want to bring attention to this recent article in Source "Philadelphia to turn crumbling piers into a waterfront park" and see what folks can share on other infrastructure that has been repurposed? As a cyclist, I well aware of many rails to trails around the country and some of the more well known, like the Highline in NYC, but there must be countless examples. Your responses could provide for a nice travelogue!
