The Old Chain of Rocks Bridge turns one year older! Help us celebrate a return to in-person bike rides and mark the 92nd birthday of this local legend. The Bridge Birthday Bash is your chance to enjoy unique routes on relaxed back roads, greenways, and the Madison County Trails.

Birthday cake for The Chain of Rocks Bridge will be provided courtesy of The Cup. Schlafly Beer is the official beer sponsor of the 2021 Trailnet Classics.
