Note the historical marker in the forefront. Compare this photo to photo #4, taken by Martin Stuppich for HAER in July of 1987. In 1987, the sidewalk railing, like the hill on Spring Street, appears to have been salvaged from a truss bridge. In this photo, you can see that steel railing has been replaced sometime in the last 22 years with this black, modern fencing.
(Mr. Stuppich also had his directions slightly askew, the bridge is oriented in a northeast to southwest direction across Duncan Creek, which flows in a southeasterly direction to the Chippewa River.)
The railing looks like it came from a truss bridge. It might have been salvaged from a truss bridge that was washed out in the flood of 1934, that is speculation and I have no idea if it is, in fact, such a railing.
The City of Chippewa Falls was organized around two moving bodies of water, the Chippewa River and its tributary Duncan Creek. Bridges soon became necessary with rapid expansion of the transportation system in the late 19th and early 20th century. By 1891, within the city limits, seven bridges crossed Duncan Creek and one crossed the Chippewa River.
This architecturally significant "Rainbow Arch Bridge" is a classic example of the small reinforced concrete bridges which began appearing around the United States in the 1890's and were built in large numbers in the early 20th century. The 93 foot single span Spring Street Bridge is contructed in the typical arch form in which the roadway is suspended from the arch. Eight concrete vertical intermediate posts on each side are jointed by the concrete floor beams. It is further characterized by the two decorative balustrade railings, and the four original lamp posts that remain intact.
The bridge was built in 1916 by the Iowa Bridge Company at a cost of $13,950. It was the only Duncan Creek bridge that survived the destructive flood of 1934.
