The complex, concrete multiple-arch Robert Street Bridge crosses the Mississippi River in downtown Saint Paul. The bridge accommodates river traffic, a railroad crossing, and roadways. The bridge is also notable for its monumental reinforced concrete rainbow arch. It was designed by Toltz, King & Day and built by Fegles Construction Company between 1924 and 1926. The bridge was added to the National Register of Historic Places in 1989. Robert Street is named after French Canadian riverboat captain, businessman, and early settler, Captain Louis Robert. One of the work crew members building the bridge was Warren Burger, future Chief Justice of the United States.
