Happy birthday to the Old Chain of Rocks Bridge!

Happy birthday to the Old Chain of Rocks Bridge!

One of Trailnet's most iconic rides, the Bridge Birthday Bash presented by BJC HealthCare, is back for 2026! Join us on Saturday, April 11 to celebrate the 97th birthday of the legendary Old Chain of Rocks Bridge and experience a piece of St. Louis history.

We have routes planned for all comfort levels, including one for younger riders. Afterwards we'll have plenty of refreshing drinks to cool you down, and we'll celebrate with some delicious birthday cake!

The Bridge Birthday Bash is your chance to enjoy unique routes on relaxed back roads, bridges, and the Madison County Trails. This ride is perfect if you're new to biking or just got back into it, but if you're up for a challenge, we have you covered, too.

We'll have all the pertinent information on parking, schedule of the day, and specific routes closer to the ride!

This ride is supported in part by the Agency for Community Transit Community Action Grants Program.
