The piers are rather unique in design.

My track chart indicates that the line here was not built until 1913 as the Macoupin County Extension Railway. The Windy Hill Road bridge has a date of 1891, but the line there was not built until 1927.

This one is curious. Three truss lines typically indicate the trusses were modified. I would expect these trusses to be very late 1880s to mid 1890s. The line was not constructed until 1913. In photo 1, it appears the trusses were strengthened at the ends with solid members, instead of laced members like what would be expected. I know there are two deck trusses in the Springfield area to the north that reused early 1880s trusses. I would assume this one was built out of reused trusses as well.

Tony,
I agree. I can't say I've ever seen anything like that.
I also did find a possible original location for this bridge, although I have not found the records to confirm.

The Iowa bridge has the same dimensions, was replaced in the 1920s, possibly when this bridge was constructed, and also used three truss lines per span. It is possible the spans were altered for single track use and moved here. I will keep looking for info on this bridge.
