In 1882, the Chippewa Falls and Superior Railway wished to build from an existing line in Wabasha, Minnesota to Chippewa Falls, Wisconsin.
The same year, the route was extended to Menomonie from Red Cedar Junction.
The route was completed to Chippewa Falls by 1883, but never was extended north to Superior. It was purchased by Milwaukee Road.
At Reeds Landing, a large pontoon bridge allowed bridges to cross the Mississippi River.
By 1882, the railroad was purchased by the Chicago, Milwaukee & St. Paul Railway. Known as the Milwaukee Road, this route became a spur for the railroad giant.
The Milwaukee Road was renamed the Chicago, Milwaukee St. Paul & Pacific Railway in 1915. By 1951, the Pontoon Bridge was dealt a severe blow by ice, and the line was abandoned from Durand to Wabasha.

The remaining portion was purchased by the State of Wisconsin in 1979, and was operated by private owners. Despite the promise, a bridge strength issue in Eau Claire would not allow train operations to be feasible, and the route was abandoned in 1981.
In the 1980s, Wisconsin turned it into a trail, and by 2004 the trail was complete to Eau Claire. The Red Cedar branch is also used as a trail.
These trails are named the Chippewa Valley and Red Cedar State Trails.

This unique bridge crosses the Red Cedar River on a heavily skewed truss.
The bridge itself has a build date of 1910 according to the Milwaukee Road Archives at the Milwaukee Central Library.
However, the truss appears to have been relocated to the present location in 1910. The original location was proven to be the original Rock River Bridge at Byron, Illinois.
The Byron Bridge was replaced in 1897, and it is believed to have been moved to the current site of the Good Thunder, Minnesota Bridge prior to having been moved here in 1910.
In addition, there is an identical truss in Fayette County, Iowa which may have a relation to this bridge as well.
Upon in depth research, this bridge was moved from Byron to Good Thunder in 1897, and here in 1910. A new bridge at Good Thunder was built from parts of the 1897 Byron Bridge.
The truss itself is a significant piece of work. The 9 panel span features a heavy 45 degree skew, pinned connections and unique portal bracing.
The structure is supported by one concrete pier, and one wooden pier. The approaches are timber.
Because of the awkward geometry between the structure and river, the best photos come from deck level.
Despite this, the photo above was taken from a canoe, thanks to a couple of fishermen who really took an interest in the structure.
This unique angle shows off the beauty of the structure and surrounding areas.

The author has ranked this bridge as highly significant, due to the build date and detailed relocation history.
