I was on my bicycle, and I was trying to hold up my phone as a flashlight, and it was terrifying at parts! It was AWESOME! I should’ve just walked it, but out of habit, I took my bicycle off of the rack.
This little trail was worth the stop just to see the cast iron lift bridge and North Dakota’s only tunnel. Trail has portajohns at beginning parking lot and is paved to bridge. The bridge surface was expanded metal over railroad ties and crosses the Yellowstone River. The trail turns to sand thru the old wooden railroad tunnel. Make sure you have a light since it gets dark in the middle but entire tunnel was dry. Short trail afterwards has a nice view of the valley but ends on private property.
Luck would have that Handicap parking is at Trail grade at the west end. Otherwise it is a steep though short climb from the park below. The trail surface across the ties is a steel reinforcement web making a smooth ride. However at the east end the dirt has washed away and the web is not bent down over the side of the RR tie. This cut the side wall of my tire. Luck again, it did not blow out until an hour later after loaded it back in my Van. If the web reinforcement was hammered down, it would cure this hazard.
