Saint louis help

I will be in grafton Ill. on bike. How can I bike from Grafton to Saint louis. Is there a trail that takes me to the chain of rooks bridge or something?

You’re in luck. Take the Vadalabene trail to the Confluence, cross the Mississippi over a dedicated bike bridge (old chain of rocks bridge) then the Riverfront trail to the Arch.

Welcome to St. Louis! You will be on one of my favorite rides. After you cross the Chain O Rocks, you will ride down the Riverfront Trail. Its 10 miles of pure biking heaven. Never crowded, decent view, and you can just fly down it.

Thank You . Could you give me directions from Grafton to the bridge?
