Three Bridges Trail runs from Pigeon Roost Road to Rockcrusher Road, part of the outer trail loop. Three Bridges trail begins with a gentle downhill switchback to a steep drop into the bottomland. There are two bridges in close proximity before the narrow trail begins a sharp uphill with some technical turns. At the top of the climb is the trail junction with Power Line Trail. Technical single track continues over some fairly rough land and crosses under the power line before reaching the 3rd bridge. After crossing the 3rd bridge the trail goes straight up a very steep hill on an old skid road. The double track continues a gradual uphill until it intersects into Rockcrusher Road.
