Classic New England covered bridge, restored and still in use. Small park on the east side, multiple good routes from the bridge west through Massachusetts and New Hampshire.

Paved route through the woods, although best taken at a slow speed to both enjoy the scenery, and accommodate runners, joggers, walkers, and small kids just learning to ride. Save the road racing for out on the roads.
