Dubuque Rail Bridge, Railway bridge between Dubuque, Iowa and East Dubuque, Illinois, US
The Dubuque Rail Bridge extends 1,535 feet across the Mississippi River, featuring a 356-foot swing span that allows river traffic to pass beneath the structure.
Built in two phases during the 1890s, the bridge replaced an earlier 1868 structure and integrated engineering innovations from the Keystone Bridge Company and American Bridge Works.
The bridge represents the evolution of railroad infrastructure in the Midwest, connecting communities across the Mississippi River while facilitating regional economic development.
Canadian National Railway operates six trains daily across this single-track bridge, which underwent structural reinforcement and connection improvements between 2012 and 2013.
The rail approach on the Illinois side passes through a quarter-mile tunnel carved into a 150-foot bluff before curving to meet the bridge structure.
