How about North Road to Evans Notch? To make it different, start in Shelbourne Village instead of the usual Hogan Road/North Road parking area near the dam. By starting in Shelbourne, you will cut out about 3 miles and 2 tough hills at the end of the ride. You add a mile of flat scenic farmland and river, not a bad exchange.
The ride goes over RR tracks and the Androscoggin River about 1 mile to North Road, then out about 5 miles to the iron bridge, crosses the river again and goes to Route 2. Ride a short distance on a wide shoulder on route 2, then take the left onto the road up Evans Notch (Rt 113).
Some will ride up to a small bridge for a nice, easy, gradual route upriver. After the small bridge, the steeper climb to the top begins. Some will climb to the top. Either way is a spectacular ride, and you can regroup down the river at the new suspension bridge for a snack. Return to the cars by reversing the route.
Mileage: about 30 if you do the whole ride to the top of Evans Notch, about 26 if you go to the bridge just before the climb goes from gradual to steep.
Shorter option? Start at the iron bridge for a really nice 16 mile ride.
Time: Ready to ride at 10:00 am in Shelbourne Village. If you want to start at the iron bridge, look for riders coming across it at about 10:20-10:30.
If you want to carpool, meet in Jackson, in the parking lot across the street from the J-Town Deli at 9:00 am.
