Original Slough Bridge 1935 Peru Centennial Information, May 25-26 1935 SLOUGH BRIDGE

An iron bridge across the slough, consisting of three fixed spans, each seventy-five feet in length, was begun on July eighteenth,1869 work having been delayed by high water, and completed in November 1869. There was a northern approach 265 feet long, built of timber. The road connecting it with the river bridge was built on an embankment 300 rods long, eight feet high, with a roadbed twenty-five feet wide.

It was thought that this embankment would raise the road above high water level, but it was flooded many times.

This bridge would be replaced by the current bridge in 1917. The old bridge was sold to a local scrap dealer for $100.00.

As a fan of Chicago bridges, any thoughts or comments?

Have you heard of Boyington & Rust?

Note the timber piers! Also, the rest of the structure, the edge of which is just caught in the image, may be more substantial that originally described in the 1935 article.
