Williston to Fairview Bridge loop — gravel

This 124-kilometer gravel loop is classified as a 'Hard road ride' and requires very good fitness due to its length and an elevation gain of approximately 530 meters. Some segments are unpaved and can be challenging, potentially requiring you to push your bike.

Cyclists with very good fitness can expect to complete the Williston to Fairview Bridge loop in about 5 hours and 15 minutes, though this can vary based on pace and stops.

The route is primarily gravel, traversing the expansive plains of North Dakota and Montana. Be prepared for some unpaved sections that can be difficult to ride, especially after rain. The landscape features rolling grassy hills, vast agricultural lands with cornfields, and some badlands.

The most distinguishing features are the historic Fairview Bridge and the adjacent Cartwright Tunnel. The Fairview Bridge, built in 1913, is a former railway lift bridge now serving as a pedestrian path with views of the Yellowstone River. The Cartwright Tunnel, North Dakota's only railroad tunnel, is also a historical engineering marvel. You'll also pass by Open Roads SH1804.

While specific parking areas aren't detailed, access points near Williston or Fairview, particularly close to the historic bridge and tunnel area, would be suitable starting points for this loop. Look for public parking in these towns.

The route passes through the Trenton Wildlife Management Area. While there are no specific entrance fees for cycling the trail itself, it's always wise to check the North Dakota Game and Fish Department website for any current regulations or permits that might apply to activities within the WMA, especially during hunting seasons.

Information regarding dog-friendliness specifically for this gravel loop is not readily available. However, if cycling through the Trenton Wildlife Management Area, dogs are generally permitted but must be kept on a leash to protect wildlife and ensure safety. Always practice Leave No Trace principles.

The best time to cycle this route is typically during the spring or fall when temperatures are milder. Summers can be very hot on the exposed plains, and winters bring snow and ice, making gravel cycling challenging or impossible. Always check local weather conditions before you go.

Given the length, elevation, and potential for unpaved sections, a sturdy gravel bike with appropriate tires is highly recommended. Carry plenty of water, as services can be sparse, and be prepared for varying weather conditions. A repair kit and extra tubes are essential.

You'll experience the vast, open plains stretching from North Dakota into Montana, characterized by a 'rolling sea of grassy hills,' extensive cornfields, and other agricultural lands. A significant highlight is the Yellowstone River, visible from the historic Fairview Bridge, and you'll also encounter unique badlands formations.

Yes, the route also passes through sections of the Cartwright Tunnel, 41st Street Northwest, Fairview Bridge, and Riverside Drive.
