Fairview Bridge & Cartwright Tunnel Trail

The jogging route is approximately 1.4 kilometers (0.87 miles) long. Most people complete it in about 9 minutes, depending on their pace and how much time they spend exploring the historical features.

The terrain varies significantly. The initial stretch to the bridge is paved. On the Fairview Bridge, you'll jog on expanded metal laid over old railroad ties. Inside the Cartwright Tunnel, the surface changes to sand, and it can be uneven. Sturdy shoes are highly recommended.

You'll experience impressive views of the Yellowstone River from the historic Fairview Bridge. The trail's main attractions are the bridge itself, an engineering marvel, and the Cartwright Tunnel, North Dakota's only railroad tunnel, with its massive timber linings. The remote setting also offers a sense of quiet solitude.

The trail is generally accessible year-round, but spring and fall offer the most pleasant jogging conditions with milder temperatures. Summer can be hot, and winter may bring snow and ice, making the tunnel's uneven ground more challenging. Always check local weather conditions before you go.

Yes, dogs are generally welcome on the trail. However, due to the unique terrain inside the Cartwright Tunnel (sand, uneven ground, and complete darkness), ensure your dog is comfortable with such conditions. Always keep your dog on a leash and clean up after them.

No, there are no permits or entrance fees required to access the Fairview Bridge & Cartwright Tunnel Trail or Sundheim Park. It is freely accessible to the public.

Parking is available at the trailhead within Sundheim Park. The trail is easily accessible from the park's designated parking areas.

Given the unique conditions, it's essential to bring a flashlight or headlamp for navigating the nearly 1,500-foot-long Cartwright Tunnel, which becomes completely dark in the center. Sturdy jogging shoes are also recommended due to the varied and sometimes uneven terrain, especially inside the tunnel.

The trail is generally considered easy and suitable for most fitness levels, including beginners. However, families with young children should be aware of the dark, sandy, and uneven conditions inside the Cartwright Tunnel, which can add a moderate challenge. A flashlight is a must for everyone.

This specific jogging route is an out-and-back trail. You will traverse the Fairview Bridge and go through the Cartwright Tunnel, then return the same way.

The Cartwright Tunnel is open for pedestrian access as part of the trail. While it's a unique experience, remember it's unlit, long, and has uneven, sandy ground, so a flashlight and careful footing are crucial.
