The Confluence Greenway consists of a network of trails and greenways on the Missouri and Illinois sides of the Mississippi River. Included in the network are the Chain-Of-Rocks Bridge, the Riverfront Trail, the KATY Trail, and the Sam A. Valadebene Bike Route. It is named after the confluence of the Missouri and Mississippi Rivers.

The Confluence Bikeway travels from just north of the Clark Bridge in Alton to just north of Niedringhaus Ave. in Granite City.

 
     
   
     
  After passing under the Clark Bridge, the trail climbs to the top of the levee along the Mississippi River.  
     
 
     
  The trail then passes by the Melvin Price Locks and Dam, and then leaves the levee through a bottomland along the river. It then crosses Wood River Creek near its confluence with the Mississippi River.  
     
     
   
     
  After crossing Wood River Creek, the trail intersects with a trail the follows the creek into Wood River.  
     
 
     
  The trail then follows the levee paralleling IL 143, and then IL 3.  
     
   
     
     
     
 
     
  As the trail crosses driveways for businesses situated on the river side of the flood wall, the cyclist is forced to navigate gates places at the bottom of the incline descending from the levee, creating a dangerous situation.  
     
   
     
  The trail passes by the Lewis and Clark Confluence Tower. There is an access ramp to the attraction from the trail.  
     
 
     
  Just past the Lewis and Clark Tower is the Lewis and Clark State Historic Site. The site features a vistors center and a reconstruction for Fort Du Bois, where the Lewis and Clark expedition wintered. The trail passes by the site of the reconstruction.  
     
   
     
     
     
 
     
  The trail then follows the levee along the Chain-of-Rocks canal. The trail surface changes to fine gravel or broken chip-and-seal for several miles.  
     
   
     
  After descending from the levee on an shared roadway, the trail crosses Old Rock Rd. and returns to follow IL 3.  
     
 
     
  As the trail continues along IL 3, a bridge carries it over railroad tracks.  
     
   
     
  The trail then follows IL 3 through Granite City, using tunnels to cross several minor roads.  
     
   
     
  The trail ends just north of Niedringhaus Ave. It is approximately 3 miles on IL 3 to the McKinley Bridge, where you can cross over the Mississippi to access the Riverfront Trail.
