Your support also enables us to keep our bike maps, and 38,158 miles of existing bicycle routes, up-to-date, ensuring that cyclists have all the information they need for safe and beautiful bicycle journeys. This past year, we updated 48 of our bike maps for your cycling convenience. Of special note: this year our Routes and Mapping specialists launched major overhauls of the Great Divide Mountain Bike Route and the Lewis & Clark Bicycle Trail.
