The completion of railroad bridges over the Missouri and Mississippi Rivers allowed all rail transport over this route.  An unpretentious white monument marks the spot which is named for a nearby creek crossed by the railroad.  The property is associated with the Railroads in Colorado, 1858-1948 Multiple Property Submission.
