You can access both sides, albiet indirectly. The locals were a big help. Right off the breezewood exit there's a travelers lodge you can stop at and the people were super friendly and helpful. About 3 doors down? A Cannondale shop who were able to show us maps of the local trails.

The bridges that connected the old turnpike were removed in 2005 for safety reasons, but you can still access both ends of the trail in between. Its basically disconnected from the turnpike commission's property unless you climb up a steep rock bank where the bridge used to be. If you end up visiting you'll see what I mean. Just look for the PIKE2BIKE signs.

I have some pictures, I'll see what I can upload.
