IDOT Region 4

IDOT’s Region 4 encompasses District 6 and District 7. Located in central Illinois, the region is home to 36,208 miles of roadways, including 3,713 state system miles. Region 4 covers a horizontal band of counties that includes the widest portion of Illinois, both the Mississippi and Illinois rivers, and hosts three Illinois Scenic Byways. In addition to the Great River Road and Historic Route 66, the Historic National Road (US Route 40) spans Illinois from the Indiana state line, just east of Weaver to the Metro-East area across the river from St. Louis, Missouri.

With numerous rail lines and spanning 32 counties, the region hosts three Amtrak corridors including stops in Quincy, Springfield, and Effingham. Bike paths and bicycle friendly roadways are numerous in this region. Take I-72 or explore the river view park system. Book a flight or take the train to the state’s capital, Springfield, to be a tourist for the day, where you can visit the area’s museums and historic landmarks, or travel to Effingham to visit beautiful Lake Sara. Options are bountiful in central Illinois.
