Good evening, I just found out about this from BikePGH. You may be interested in it if you're going to ride in PGH, and it might help us draft our own map. http://www.bike-pgh.org/campaigns/commuter-bike-maps
I took a quick look at it. I don't see recommended routes, but they list bike shops, trail access, things like that. It's a Google map with landmarks basically. Come to think of it you could put recommended routes on with "MapMyRide.com" - hmmmm....
