Lake Street-Marshall Avenue Bridge, Spanning Mississippi River, Minneapolis, Hennepin County, MN
Significance: The bridge is a major 19th century engineering accomplishment and has been a significant transportation link for nearly 100 years. Constructed entirely of wrought iron with a wooden deck, the bridge was at that time the second longest-span metal arch bridge in the United States, exceeded only by the Eads Bridge in St. Louis. Today, the Lake Street/Marshall Avenue Bridge is still the fourth longest-span 19th century metal arch bridge remaining in the United States and is the longest-span three-hinged arch bridge surviving in the country. The bridge has been, and continues to be, a significant transportation link between the cities of Minneapolis and St. Paul. In 1961, before the opening of Interstate 94, the bridge was one of the heaviest traveled, two-lane bridges in the United States, carrying over 25,000 vehicles per day. In December 1979, the Keeper of the National Register, concurring with the Minnesota State Historic Preservation Office, and the Federal Highway Administration, certified the Lake Street-Marshall Avenue Bridge as eligible for inclusion on the National Register of Historic Places.
