Built by the Great Northern Railway, the multiple-span, through-truss lift bridge spanning the Yellowstone River (visible from ND 200 crossing bridge) is a well-preserved example of early-twentieth-century railroad bridge engineering. The bridge replaced a ferryboat in the same location. Although river traffic had ceased long before construction, federal regulators deemed the Yellowstone to be a navigable waterway, necessitating a lift mechanism. Today, this is the lone vertical lift bridge in the state. The bridge connects with a curved tunnel as the railroad ascends the east bank into North Dakota. A gatehouse keeper stationed twenty-four hours a day at the east end of the bridge collected a small toll for raising the gate to allow automobiles and farm trucks to cross the planks on the same span that accommodated railroad trains.
