History

The nine bridges that make up the Metal Highway Bridges of Fulton County were all constructed between c. 1880 and c. 1915. All nine bridges were and are located on county and township

 roads in rural settings, and are all very similar in their construction materials and methods. They are early examples of steel truss bridges in Illinois.

Construction

The bridges in Fulton County exhibit two types of steel truss bridge construction, Pratt bridge and Parker, which were the most common early types of steel truss bridges. Due to variation within each type of bridge, the collection in Fulton County offered a unique opportunity to view the evolution of late 19th and early 20th century steel truss bridge construction. For example, the now-demolished London Mills Bridge, a Pratt built in 1883, features pinned connection and double eyebar

Each of the bridges utilized similar construction materials; each one is/was almost all steel, with the possible exception of the London Mills Bridge and the Seville Bridge. Those two bridges—only the Seville still stands—are mostly steel but may include some iron

 construction due to their age. The bottom chords of the bridges range from 140 feet (42.7 m) to 200 feet (61 m) and the width averages 16 feet (4.9 m). In their massing, each bridge displays the lightness characteristic to metal bridges of the time period, although the later bridges began to exhibit characteristics more associated with modern steel truss bridges.

Destruction

The Elrod Bridge was completely destroyed by an F-4 tornado that moved through Fulton county during a 1995 tornado outbreak.

Significance

Together, the nine steel truss bridges stood out because of their proximity to each other within Fulton County. Indeed, they also held historical significance for their age and as examples of early steel truss bridge construction; but it is rare to find such a concentrated collection of so clearly related sites. When they were nominated for the National Register of Historic Places in 1980, before some were destroyed, they were the subject of local tours by canoe
