Southern Links Trailway
I have to give high accolades to the trail designers. At each gravel road, they built a paved apron over the road so road bikres don't have to dismount to get through the sometimes loose and sharp gravel.
This is a brand new rails to trails project in northwest Lapeer County Michigan connecting the villages of Columbiaville, Otter Lake and Millington. I discovered it while putting in bicycling directions from Rochester to Traverse City using the new bicycling option on Google Maps. The newest section of the trail between Otter Lake and Millington is scheduled to open spring 2010.
