IDOT Region 1

Serving one of the most populous urban areas in the nation, IDOT‘s Region 1/District 1, located in northeastern Illinois, includes the state’s most recognizable city, Chicago. This region is home to six counties: Cook, Lake, McHenry, Kane, Dupage, and Will.

The nation’s second busiest airport (O’Hare), one of the country’s three main inland distribution centers (Chicago), and the port of Chicago itself all are located in this region. Annually, the region's 28,060 centerline miles of roads (2,775 state-maintained) feel the impact of more than

650 million passengers utilize the Regional Transportation Authority's (RTA) rail and bus
services. RTA is the largest transit system in the
state and third largest nationally. Chicago’s Union
Station, a hub for commuter and inter-city passenger rail connections, is the fourth busiest Amtrak station in the nation.

Add to this hundreds of miles of bike paths, bike lanes and sidewalks and pedestrian paths, and you can quickly see that Region 1 is a complex multi-modal transportation hub with a mode of transportation for everyone.
