In the U.S. state of Illinois, U.S. Route 67 is a north–south highway through the western portions of the state. It runs from the Clark Bridge in Alton north to the Rock Island Centennial Bridge in Rock Island. This is a distance of 213.99 miles (344.38 km).
U.S. 67 is the major north–south corridor for western Illinois, and the only major Illinois north–south highway route from 1918 that was never upgraded to the Interstate highway system.
US 67 enters Illinois from Iowa by way of the Centennial Bridge that cross the Mississippi River. It is mostly two-lane highway from Rock Island to Monmouth where 67 intersects US 34. From Monmouth, US 67 is interplexed with US 34 until US 34 exits to run west toward Burlington, Iowa. From Monmouth to Macomb, US 67 is a "Super Four" 65 mph (105 km/h), four-lane highway. The Roseville Bypass was one of the last bypasses for this section and was completed in 2002. There is a section at Good Hope where the highway runs through town with signals and an at-grade rail crossing. In Macomb, US 67 runs through town as a four-lane arterial road which has an at-grade railroad crossing and several signals. Exiting Macomb, US 67 is a two-lane highway until it reaches just west of Chapin. From west of Chapin to just north of Roodhouse, US 67 is a "Super Four" 65 mph (105 km/h), four-lane highway. Immediately around Jacksonville US 67 is limited access. The limited access section runs for approximately 7 mi (11 km). From where the four-lane highway ends north of Roodhouse to 7 mi (11 km) south of Jerseyville US 67 is a two-lane highway. South of Jerseyville, US 67 is a four-lane highway until which exits to run south at the beginning of Illinois Route 255. US 67 is then an urban roadway until it exits Illinois by way of the Clark Bridge across the Mississippi River.
