J.R., this bridge carried two bridges by the same railroad. The first being built in the 1800's then the second in 1923 when the railroad double tracked this area. The first bridge was in place with the second from 1923-1953 when the first bridge was demolished because CTC was installed. This can be clarified by seeing an about 200 ft. portion of track there between the spur and the main line.
now that you mention it it really does look like that. I also think that because there is some EXTREME spurs to the north of the bridge and a abandoned track there and a old UP/MP bridge so I agree with you
This is a rather interesting span. The piers appear to have carried two bridges at one time, and my bet would be the bridges were owned/built by competing railroads. Note the difference in the building materials of the piers from upriver side to the downriver side.
It is reminiscent of the bridges over the Mullet River, in Plymouth, Sheboygan County, Wisconsin, where competing railroads built parallel bridges on the same abutment. Both lines had differences of opinion in how to build bridges, so the abutments are built with two different materials, each according to the particular railroad's building specs.
Does anyone have any pictures of the old 141 bridge that used to be next to this railroad bridge (and looked just as old and rusty). I think it was torn down in the mid 80s. I was remembering it today when I saw old pictures of the 1982 flood on stltoday dot com, but there were no pictures of the bridge (or the railroad bridge).
