Third Avenue Bridge (Bridge 2440)
History & significance
The Third Avenue Bridge spans the Mississippi River near St. Anthony Falls in Minneapolis. Constructed between 1914 and 1918, it is an example of Melan arch construction. The patented Melan arch design uses a concrete reinforcing system with metal I-beams curved to the form of the arch and embedded in concrete. The bridge features five concrete arch spans, each carried by three arched ribs, and Classical Revival detailing, including an ornamental metal and concrete railing added in 1939. The reverse S-curve alignment and spacing of the arches was intended to avoid dangerous limestone breaks. It also produced an aesthetic form that added to the bridge’s overall image as a gateway to downtown Minneapolis. The Third Avenue Bridge is significant as the last major reinforced-concrete Melan arch bridge constructed in the Twin Cities. It is also a contributing element to the St. Anthony Falls Industrial Historic District.
