IAIS - Ashworth Park Bridge
Posted November 20, 2020, by John Marvig (marvigj27 [at] gmail [dot] com)

This one is curious. A 1897 date stamp, and the bridge appears to have been a ca. 1900 to ca. 1905 span. The old second track (http://bridgehunter.com/ia/polk/bh75590/) gave a date of 1901.

The replacement contractor gives further information:


"The bridge was originally built in 1902, piers rebuilt in 1943. "

Except, it appears the piers were part of the 1897/1901 bridge. The 1902 date does seem appropriate for the truss. There are two other bridges on this line that also appear to have been moved in the mid-1940s:



The Rock Island did a lot of realignments in southeast Iowa during the mid 1940s, and at least 3 spans like this are have known to existed down there. It is possible that these spans could have all been moved from out east as the railroad upgraded lines.

Not a CGW Bridge. Only a RI, and M&StL had trackage rights.
