Town of Marshfield, Fond du Lac County WI. – The Wisconsin Historical Society announces the listing of the Palm Tree Road Bridge in the National Register of Historic Places on December 12, 2022. The bridge spans the Sheboygan River in the Town of Marshfield in Fond du Lac County.

The Palm Tree Road Bridge is listed on the National Register as a stone nine-arch bridge of statewide significance that has changed little since it was constructed in 1901. Bridge historians consider it unique in Wisconsin for its classic Roman profile, with an uneven number of arches that are not quite semi-circular. The largest arch is in the center, and it is flanked by four spans of increasingly smaller size on each side.

The bridge, also known as the Nine-Arch Bridge, was built by mason Alphonse Halter, a resident of nearby Mt. Calvary. The bridge was singled out for acknowledgement in 1962 by Richard W.E. Perrin, an early Wisconsin advocate for identifying and understanding historically significant structures in the state. This is the only nine-arch stone bridge in existence in the state.
