Street View 


This massive Warren pony truss bridge is located right in the heart of Wauwatosa, WI, and carries the Canadian Pacific RR over the Menomonee River. This bridge's most unique feature is its three trusses, where most truss bridges only have two. The date plate on the west end of the bridge is only partially intact but shows a 1905 build date, while a stamp on the west abutment shows a 1909 build date. This bridge is extremely massive, especially for a truss bridge built this early in the 20th century. All connections are riveted, and lattice is present under the upper chord. The diagonals are built up and feature plate steel rather than the more-conventional V-lacing or battens. Two separate tracks pass over the bridge. This bridge is easily viewed from a pedestrian MOB located adjacent and parallel to it.

Menomonee River Railroad Bridge

This is a Canadian Pacific Rail line. I go here all the time. Union Pacific runs far north of here by butler yard.
