Location

Built as a replacement for an aging and no longer sufficient former bridge built in 1941, the new bridge started construction in late 2007. With the completion of the Great River Road Bridge in late 2009, the existing bridge was demolished. The modern structure is applauded for its sensitivity in design for its scenic natural surroundings (including the Mississippi River, Bellevue State Park, and the high limestone bluffs that tower above). Built with a two-lane 40-foot driving deck, it also provides a 12-foot bike and pedestrian lane on its western side. The bridge also crosses a Canadian Pacific rail line that travels through Bellevue parallel to US 52. In 2017, its average daily traffic was 2,430 vehicles, with 7% of that being truck traffic. The bridge also had poles with butterfly-shaped tops.
