Chain of Rocks Bridge over Mississippi, connecting Illinois, Missouri
The historic Chain of Rocks Bridge connecting St. Louis, Missouri, and Madison County, Illinois, has a tricky bend in it. Today, that quirk is “just that” for pedestrians and bicyclists who move over it as part of a trail network. The Chain of Rocks Bridge – at over 1 mile long – spans the Mississippi River. After its construction from 1927 to 1929, the bridge’s 24-foot-wide roadway supported vehicular traffic and Route 66 – until it closed in 1970. Before then, that quirky 22- or 30-degree bend was a bit scary. More about that here .
