Franklin Avenue Bridge spanning the Mississippi River
The Franklin Avenue Bridge, officially the F.W. Cappelen Memorial Bridge, carries Franklin Avenue over the Mississippi River in Minneapolis, Minnesota. It was designed by Frederick William Cappelen, assisted by Kristoffer Olsen Oustad, both of whom were among four important Norwegian-Americanengineers working in the region at the time. The reinforced-concrete open-spandrel arched structure was completed in 1923. The bridge's overall length is 1054.7 feet (321.47 m), with a central span of 400 feet (122 m). It was added to the National Register of Historic Places in 1989 along with several other area bridges as part of a multiple property submission.

The Cedar AvenueBridge is historically significant as an excellent example of the monumental urban, continuous-rib-arch, reinforced concrete bridges constructed in the Twin Cities to span the high and scenic Mississippi River bluffs during the early automobile age.
An additional point of technological significance is that the Cedar AvenueBridge was one of the first constructed using water-cement ratio specifications for proportioning concrete.
The Cedar AvenueBridge is the crowning achievement of Kristoffer Olsen Oustad, who is significant as one of four, major, innovative and influential Norwegian-American engineers that were involved in the design of the great bridges of the Twin Cities.
