Long Meadow Bridge (Bridge 3145)
Design and construction of an exceptionally long bridge utilizing Camelback through trusses in order to address design challenges across the wide overflow of the Minnesota River.
History and significance
The Long Meadow Bridge spans Long Meadow Lake on the alignment of Old Cedar Avenue in Bloomington. It was constructed in 1920 and consists of five steel Pratt through trusses in a Camelback configuration with riveted connections. It is significant for exhibiting exceptional engineering skill to meet unusual site conditions posed by spanning the wide overflow of the Minnesota River. When constructed, it was the longest steel highway bridge with concrete flooring in the state. Today it remains as the state’s longest Pratt through truss bridge, and is one of only five bridges using a Camelback through truss system.
