The Chain-Of-Rocks Bridge / Old U.S. Route 66

     
     
     
 

 
     
 

The Chain-of-Rocks bridge is the centerpiece of  the Confluence Greenway, a network of trails in the area of  the confluence of the Missouri and Mississippi Rivers, both in Missouri and Illinois. This is the only truly bicycle-friendly crossing of the Mississippi River within several hundred miles. The bridge is owned and maintained by Trailnet Inc., and is open weekends from 9:00 A.M. till 5:00 P.M..

  
     
 

 

  

 
     
     
 

 

  
 

On weekends, Vendors selling fresh produce and snack items greet you as you approach the bridge. Friendly volunteers greet you with cold water and information as you step onto the bridge.

  
     
     
 

 
     
     
     
 

  As you walk, skate, or ride across the bridge, the view is of the I-270 bridge to the north, and the low dam that gives the bridge its name, with the skyline of downtown St. Louis in the distance featuring the Gateway Arch to south.

  

    
 
     

 

     
     
     
 

 As part of the Confluence Greenway, connections to the bridge with the St. Louis Riverfront Trail, and the 4,000 plus acre Columbia Bottoms Conservation Area at the actual confluence of the Mississippi and Missouri Rivers several miles to the north, as well as connections with trails on the Illinois side of the river make the bridge and integral component of bicycle transportation in the Metro St. Louis/Metro-East area.
