UP - Cahokia Creek Bridge

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.
