The Third Avenue Bridge is an 11-span bridge over the Mississippi River in downtown Minneapolis, Minnesota. The bridge's construction consists of two steel spans over West River Road, five spans of three concrete deck arch ribs over the river, two spans of concrete deck barrel arches over the river and two prestressed concrete girder spans over Main Street.
Opened in 1918, the Third Avenue Bridge was placed on the National Register of Historic Places under Criterion A as a contributing element to the St. Anthony Falls Industrial Historic District and Criterion C for its engineering significance. HNTB is responsible for the final design of this complex bridge rehabilitation project and serves as an extension to the client during construction.
