Monroe County, Illinois has a rich and fascinating history that dates back to the early 1800s. The county was officially established in 1816 and was named in honor of James Monroe, the fifth president of the United States.

The county seat, Waterloo, became a hub for businesses and attracted residents from surrounding areas. The growth of industry and commerce brought about the need for better transportation and infrastructure systems, leading to the construction of bridges and roads.
