Significance: The bridge is significant for its associations with the homestead boom in Montana and the part the bridge played in diverting an attempt by county divisionists to create a new county out of portions of eastern Sweetgrass County. The bridge is one of the older bridges on the Yellowstone River and a representative example of the pin-connected, Park through truss. The bridge is also significant for its association with the Security Bridge Company of Minneapolis, Minnesota, and Billings, Montana, the most prolific early-20th century bridge building firm in Montana.
