p. 83, Chicago & Eastern Illinois Railroad In Color by Edward M. DeRouin shows a steel trestle that uses trusses instead of the normal girders between the towers. The satellite image indicates it has been rebuilt using concrete piers. I can't tell if the spans used concrete or steel girders.
From the caption for the bridge photo:
Between Nielson and West Vienna the single track C&EI granted the CB&Q trackage rights on June 1, 1910. This action gave the CB&Q a route to Paducah, Kentucky and a link to Dixie. The two roads sharing a common right-of-way through the hilly forests of this part of Illinois make sense....1970.We have already seen a major trestle bridge near Shelbyville, IL to help mediate the valleys of Southern Illinois.
