The 33-mile Meeting of the Great Rivers National Scenic Byway begins in Hartford at the intersection of Illinois Route 3 and New Poag Road. The byway winds west and north via Illinois Routes 3, 143 and 100. Illinois Route 100 takes visitors outside of Alton and bends along the forested river bluffs approximately 25 miles to its ending point in Grafton at Pere Marquette State Park.
The byway is a natural wonder of the region where visitors can see the convergence of three great rivers - the Mississippi, Missouri and Illinois. Sites along the route include the Army Corps of Engineers’ Melvin Price Locks and Dam in Alton, Illinois, as well as the National Great Rivers Museum, located next to the lock and dam. The Army Corps’ Rivers Project Office offers numerous boating, fishing, hiking and wildlife viewing opportunities along the byway, and the area is a renowned bird flyway.
The other wonders of Illinois are: Rend Lake in Benton, IL, Wrigley Field in Chicago, Baha'i House of Worship in Wilmette (Chicagoland), Starved Rock State Park in Utica, Allerton Park and Retreat Center in Monticello, and Black Hawk State Historic Site in Rock Island.
