The National Corridor Plan identifies numbered corridors in a template that shows where U.S. Bicycle Routes will be developed and how they will connect between states. It provides a visual for how the 50,000-mile network will look when it's complete.

To date, 11,053 miles of U.S. Bicycle Routes have been established in 23 states: Alaska, Arizona, Florida, Georgia, Kentucky, Idaho, Illinois, Indiana, Kansas, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, North Carolina, Ohio, Tennessee, Utah, Vermont, Virginia, Washington and the District of Columbia.
Undeveloped corridors are shown with colored lines and developed corridors that have been designated as U.S. Bicycle Routes are shown with solid black lines. Corridors can be added or realigned depending on the opportunities and interests of a given state. Click on a state on the map above or scroll down to see a summary of each state’s progress.
