From a press release:

“[T]he Mayor and other officials announced the “Connect the Circuit” campaign to complete  the network of pedestrian and bike trails currently throughout the 9 county area (Pennsylvania and New Jersey).  When the trail network is complete, it will measure 750 miles long. Along with the announcement, the Circuit Coalition unveiled a new website – www.connectthecircuit.org – one of the central features of the new campaign.  It is designed to keep people updated on progress, as well as to allow pedestrians, bikers, and all residents to map out routes and interact with each other.  You might know Geoff DiMasi and the folks at P’unk Avenue, who were responsible for building the site.  It’s the first of its kind in the area, using existing and proposed trails that appear on a full screen Google Map that never reloads.”
