 The first section of unbannered route stretches from Chester to near Fall Creek.It begins at the approach to the Chester Bridge, following IL 150 and the remainder of the truck bypass back to IL 3, which carries the Great River Road all the way to East St. Louis.But instead of continuing along IL 3 through the riverside industrial areas, the route turns east on I-55 / I-70, north on IL 111, and back west on I-270 to rejoin IL 3 in Granite City.
