Route description

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.[3] 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.[4]

Route 84 near Rapids City

Continuing north, IL 84 is now following the Great River Road. It passes Campbell's Island and passes through Hampton. Southeast of Rapids City is the interchange with Interstate 80. Due to the proximity of the Mississippi River, the interchange is a partial cloverleaf, as a diamond interchange would extend over the river.[5] The route follows the bend in the river north through Rapids City and Port Byron.

North of Port Byron, IL 84 travels to the north-northeast towards Cordova. Three miles (4.8 km) north of Cordova, the highway separates the Cordova Dragway Park to the east and the Quad Cities Nuclear Generating Station, operated by Exelon, to the west. Between the nuclear plant and Albany lies a small industrial area bordered by the Mississippi River. Across the road lies irrigated crop land of Rock Island and Whiteside Counties.

History

The bridge over the Galena River in Galena. This bridge is part of the Illinois Route 84 / U.S. Highway 20 route.

In 1924, SBI Route 84 was originally what is now Illinois Route 92, Illinois Route 192 and Illinois Route 94 from near Muscatine, Iowa to U.S. Route 67. This was dropped in 1939.

In 1955, Illinois 84 was applied on a former alignment of U.S. Route 6. In 1964, Illinois 84 arrived at its current terminus, replacing then Illinois Route 80 north to Galena due to construction of Interstate 80 through the Quad Cities.[2]
