Facts 

Overview
Lost Pratt through truss bridge over Menomonie River on Marinette CTH JJ - Menomonee CTH S-4 (Shakey Lakes Road) in Town of Wagner
Status
Replaced by new bridge
History
Built 1894 by Wisc & Mich Railroad; converted to road use 1938; Replaced 1991
Design
Two-span Pratt through truss with pin connections. One span is 7 panels, 388' in length. The short span is 5 panels, 162' in length.

"The Wisconsin & Michigan Railroad Bridge is an example of a pin-connected Pratt through truss, a standard design used during the late 19th century. The bridge is unusual, in that it consists of two unequal spans, one measuring 162 feet and the other 221 feet. The long span may be one of the longest Pratt through trusses in Wisconsin and Michigan. In addition, the bridge is one of only a few extant trusses built before 1900. The history of the railroad bridge documents the development and decline of the logging industry in northern Wisconsin and Michigan."

--Diane Kromm, November 1989
