Historic Duluth/Superior Bridge

On this day in Duluth and Superior in 1961, the Duluth-Superior Bridge opened to automobile traffic, the first modern bridge to span the St. Louis Bay between the neighboring cities, known since the 1890s as the Twin Ports. The new span replaced the Interstate Bridge, a swinging toll bridge that stretched from Rice’s Point in Duluth to Connor’s Point in Superior from 1897 until 1961. (It was partially dismantled in 1971, and a remaining portion of the bridge still stretches from Rice’s Point and is used as a fishing dock.)
