Located in the town of Whitewood, northwest of Rapid City is yet another example of a historic railroad truss relocated to South Dakota.
Originally built in 1889 as an approach for a bridge in Clinton, Iowa, this span was one of four similar spans relocated to branch lines when the Clinton Bridge was replaced in 1909.
Another nearby bridge at Oral and a bridge in Northern Wisconsin also are comprised of the other three relocated spans.
Frugal railroads oftentimes reused spans to save money. The only span was relocated from the above mentioned Clinton bridge in 1910. It were originally constructed as an approach span in 1898, only 12 before being replaced.
Had a double track bridge not been required for the Clinton crossing, it is safe to say that these spans would have been heavy enough to carry traffic into the present day. This is one of the heaviest 19th century railroad trusses the author has ever seen.
Consisting of a single 7-panel pin connected Pratt Through Truss bridge, the bridge also sits on concrete abutments.
A plaque has been removed, and the cutout in the lattice portal has been covered. However, it still clearly reads as 1898 from behind.
Overall, the bridge remains in good condition and will likely continue to carry modern loads for years to come.

The author has ranked the bridge as being regionally significant, due to the age and relocation history.
