RRVT - Unnamed Stream Bridge
Posted October 28, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

Visited this bridge today. It is apparent that this is an early deck girder span, however it has been heavily modified and a second set of girders added to “double up” the structure. Based on the railroad, the late 1910s substructures and the very early girders, it is also likely it was relocated to this location. The structure also bears some resemblance to this structure, which was built in 1879 (confirmed by railroad documents):

Further research will be conducted. Unfortunately, this bridge was demoted as a Y-series bridge, which the Milwaukee Road Archives has had little to no luck on finding information.
