The trail runs on the old railroad right-of-way for about 2.5 miles, and around mile 6, you'll see remnants of a wooden trestle. And in the two photos below, you'll see an active rail line passing over the trail on its high trestle.
Bikers are warned not to be under the trestle when a trail in above, though they have built an awning over the trail to protect riders and walkers from falling debris.
This trail was the "Trail of the Month" in June of 2007. You can see the article on the Rails-to-Trails website here. It is a lovely ride, and the lack of road crossings adds to the enjoyment and safety of the trail.
