This bridge crosses an abandoned rail right-of-way that was once Milwaukee Road trackage. It carries the Union Pacific on a major route for the railroad. The bridge was built by the Chicago & Northwestern Railway, probably in the late 19th century.
The bridge is located in West Allis, Wisconsin, in western Milwaukee County. It is just south of I-94, across from the Milwaukee County Zoo and within 300 yards of the Zoo Interchange.
