Illinois Route 84 (Route 84 or IL 84) is a long state highway that runs along the Mississippi River in northwestern Illinois. Illinois 84 runs from south of Green Rock (now Colona) at U.S. Route 6 to the Wisconsin state line at Highway 80 by Hazel Green, Wisconsin. Illinois 84 is 93.93 miles (151.17 km) long.
Illinois Route 84 begins at an intersection with U.S. Route 6 (US 6) south of Colona in Henry County. From US 6, it heads north into the Green Rock neighborhood of Colona, crossing the Hennepin Canal on the south side of town. Colona and Green Rock were separate communities, but in 1997, became the first communities in Illinois to merge. Route 84 curves to the west, becomes a four-lane road, and crosses the Rock River into Rock Island County.
Near the TPC at Deere Run golf course, the route turns to the north towards Carbon Cliff. It curves gently to the northwest where it meets the Route 5 and Route 92 expressway at a partial cloverleaf interchange. Route 92 joins Route 84 and they travel together through Silvis for 1 1⁄2 miles (2.4 km) before Route 84 splits off to the north in East Moline.
