Of the many truss bridges on the Calumet Sag Channel and the Little Calumet River, most are from the 1950s and 1960s and even the early 1970s. This bridge dates to 1931 and is one of the oldest truss bridges on these waterways. As such, the bridge stands out among the group as significant, an assessment further supported by the fact that the trusses retain good historic integrity. The bridge is a traditionally composed example of a 1930s through truss bridge.
There was concern some time after the bridge was built that increased clearance would be needed for boats on the Calumet Sag Channel. Plans for the bridge drawn up at this time included the potential for adding lift towers to the bridge in the future to convert the fixed truss bridge into a vertical lift bridge. These changes never came to be however.
