This large double stone arch crosses a small unnamed creek near Baraboo.
Originally constructed in 1881, the bridge was widened in 1896 to accommodate a second track.
This type of rebuilding by adding a second track was common along Chicago & North Western routes, along with many other railroads. It was popular, because the existing structure could easily be added onto without having to demolish the old structure.
Overall, the bridge appears to remain in good condition, as most stone arches do.
The author has ranked this bridge as being moderately significant, due to the older age of the arch.
