Located in Bangor, this through truss bridge carries the La Crosse River State Trail over Dutch Creek.
Built in 1913 to replace an older bridge of a similar design, this bridge features a single riveted Quadrangular Through Truss, set onto concrete and stone abutments. The bridge also utilizes an A-frame portal and heavily built members.
The Quadrangular design was highly popular with the Chicago & North Western, due to the strength, particularly during derailments. Most of these types of spans were built in the 19th Century, or very early in the 20th Century. This appears to be one of the last orders of these style spans.
The previous bridge likely was relocated to a branch line, although no evidence has been found of where it may have ended up. Railroads typically reused spans that were still serviceable to save money.
In addition, another bridge in the La Crosse area features an identical design.
Overall, the bridge appears to be in good condition, with little serious deterioration on the bridge noted, other than minor spalling on the concrete.
The author has ranked this bridge as being moderately significant, due to the truss design.
