The Half Chance Iron Bridge, also known as the Half-Chance Bridge, is a historic single-span wrought iron bridge located near the small community of Half Chance, between the towns of Linden and Dayton in rural Marengo County, Alabama.

It is on Marengo County Road 39 over Chickasaw Bogue Creek.

The Half Chance Iron Bridge is approximately 1/4 mi.

It was built by the King Iron Bridge Manufacturing Company of Cleveland, Ohio in 1880.

As early as 1878 it was manufacturing many types of truss, combination, and wooden bridges and by the 1880s it was the largest highway bridge work in the United States.
