Spanning the I and M Canal in Marseilles is a pony plate girder swing bridge. It was built by Manufactures Bridge Company in 1887. It was operated by hand with a crank gear system in the middle of the bridge. The largest span is 65 feet. Total length is 130 feet. This was part of the Rock Island System. It is currently abandoned.
There was a charge of $1.00 per car to cross the canal.
