The Windham Regional Commission has created Bicycle Suitability Maps. This map series provides information about roads in the Windham Region, including traffic volumes, shoulder suitability, steep grades, bike shops, cycling opportunities, and cycling hazards. The maps should help cyclists understand the types of conditions they may encounter on these roads and choose appropriate cycling routes through the region. While primarily for “road” cyclists who do most of their riding on paved roads, all roads are shown on the map, and those unpaved roads that may be of interest to road cyclists are highlighted.
