Mississippi River Bridge

The Mississippi River Bridge combines two distinct sections: the Cass Street cantilever bridge and the Cameron Avenue tied-arch bridge, spanning 2,532 and 2,573 feet respectively.

The original Cass Street section opened in 1939 to replace the Vernon Street swing bridge, while the Cameron Avenue addition was completed in November 2004.

The structure, known locally as the Big Blue Bridges, serves as a central connection point between Wisconsin and Minnesota communities across the Mississippi River.

The bridge carries four lanes of US Routes 14 and 61 along with Wisconsin Highway 16, providing clearance of 67 feet for river navigation.

Metal decking replaced the original concrete surface of the Cass Street section in 1983, enabling continued service alongside the newer Cameron Avenue span.
