Old Humpback Bridge


Bridge Site

This is where the bridge used to be. The bridge was removed in the late 80s but the rr cut still existed at that time. Through the 90s, there was no way to cross the cut at this location. You had to go west 1 mile then north. At some point, the cut was filled at this location allowing the road to continue north.

This was a old hump back bridge that was removed in the late 1980s. The bridge spanned what was (I think) a branch of the Rock Island RR. I will have to update the history of the rail road line at a later date. It's the same line that crossed the High Bridge over the Little Sioux river. The high bridge is listed as the 'Webb High Bridge' here.

I am looking through my dads slides to see if I can find some photos that he took.

I had to figure out why I thought it was CRI&P. I was fairly sure Its the same track that goes through Royal and Rossie. I know that the track through was RI. I forgot about the fact that the C&NW took over the line when the Rock Island went out of Business in 1980. The line originally was Rock Island's when it was first built till 80 or 81. UP actually owned it when was abandoned around 1999.

The line that existed under here was a line of the Chicago & Northwestern.
