Along the former Chicago & North Western mainlines, there are numerous road bridges utilizing former railroad bridge parts. This structure is no different.
Built in 1900, the bridge has served traffic crossing Yates Avenue for quite some time. The bridge features a pretty basic double intersection Warren Pony Truss, which has been converted to road use.
From a basic inspection, one can assume that the bridge was extensively rebuilt for road use. Improvements likely included the removal of the original railroad deck and many structural steel components.
One of these improvements was the construction of outriggers, to strengthen the deck. As a result, while the existing truss was built in Phoenixville, Pennsylvania; the improvements were made using Illinois Steel Company steel.
As for the original location and build date of the bridge, it is likely that the truss dates to the 1880s. However, the original location of the bridge has not yet been determined.
It is possible that it could have originally been located somewhere close by, such as a crossing of Linn Creek. However, other similar crossings have shown that the spans could have come from anywhere.
The bridge overall contains the truss, which features riveted connections. In addition, the bridge is approached by trestle spans and rests on wooden piers.
The author has ranked the bridge as being moderately significant, due to the unique design and interesting history.
