The Stewart River Bridge is a classic reinforced concrete arch highway bridge, originally built by the Department of Highways in 1924 during the construction of the original north shore highway. It was significantly modified in 1939 as part of improvement projects along the north shore, when it was both widened and lengthened. The current ornamental railings and the south face of the bridge date from this project, as well as 10 feet of the concrete structure at each end. Surprisingly, this bridge has held up rather well to the test of time, and was given a 92.9 sufficiency rating by MnDOT in 2009.
