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.

Rehabilitation

Completed in 2023, Bridge 2440 underwent required repairs to address its deteriorating condition and ensure people and goods could safely move in and out of downtown Minneapolis. Some highlighted repairs included: removal and replacement of the deck, rehabilitation of the ornamental railing panels, and repair to piers, arch ribs, and barrel arches. The railing was elevated on a concrete curb to achieve the required height standard and previous openings were narrowed to code-required dimensions using narrow bent bars. Spandrel columns were removed and replaced with new spandrel cap beams closer to the original design. The character-defining Melan arches received extensive repairs along with cathodic protection to reduce further chloride deterioration.
