IANR - Cedar River Bridge
Posted July 20, 2016, by Peter Schierloh (forthbrdge [at] aol [dot] com)

The stone pier that used to rest under the old north approach trestle used to support a fourth TPG span. A derailment in the 1970's on the CRIP destroyed the TPG span and severely damaged the pier. The CRIP replaced the TPG span with a open deck pile trestle that they tied into an existing approach trestle that also received some damage in the derailment. I have a copy of the newspaper article on the derailment somewhere, if I find it I will try to post it.

The damage from the derailment and the hasty construction of the replacement trestle resulted in significant settlement problems with the timber trestle, so the IANR replaced the north approach trestle with a BNSF/UP joint standard precast concrete trestle. To satisfy the DNR hydraulic requirements, the stone pier was removed when the trestle was reconstructed.

Dylan,

I think the unused stone pier under the approach is from the flood of 1960 (when the girder was built), as that flood created problems in southern Minnesota and northern Iowa. Just a guess.
