The Adventure Cycling Route Network, developed by Adventure Cycling Association since 1974, comprises over 52,000 miles of routes for bicycle touring in the U.S. and Canada and is the largest such network in North America.
The routes eschew high-traffic roads and big cities for rural two-lane highways and small towns.
Routes have been designed to allow for daily stops for food, supplies, and lodging.
Adventure Cycling's first route was the TransAmerica Bicycle Trail, which they developed leading up to the 1976 Bikecentennial celebration.
Adventure Cycling is the only national organization providing staff support to develop the United States Bicycle Route System (USBRS), which when complete will comprise over 50,000 miles of bicycle routes connecting urban, suburban, and rural areas throughout the U.S.[2]
