Existing Deck Parks

I was able to speak briefly on the phone this morning with Peter Harnik. He wrote the book Ubran Green, which is where I first read about the abundance of highway deck parks. He is the director for the Center for City Parks Excellence, a division of the Trust for Public Land. www.TPLorg/CCPE
This will likely be a good research source for my classmates who are looking at projects in urban areas.
He has shared with me a list of all 26 existing parks over highways in the U.S. Now I just need to decide which ones are most applicable and most documented. Thanks for your help Mr. Harnik!
