Illinois Central Stone Arch Railroad Bridges, Dixon

The Illinois Central Stone Arch Railroad Bridges are a trio of limestone railroad bridges in the city of Dixon, Illinois, United States. The bridges were constructed between 1852 and 1855 as the Illinois Central Railroad laid its first rail lines across the state of Illinois. They were designed by Robert F. Laing for Laing and Douglas Construction Company, a railroad company contractor during the 1850s. Though each limestone bridge is similar in design, they each have different clearances ranging between 12 and 15 feet. The bridges remained in use by the railroad until 1985, and the three bridges were added to the U.S. National Register of Historic Places in 1987. ()
