Transportation System

In Illinois, businesses, residents, and visitors have access to one of the largest and most effective multi-modal transportation systems in the nation. This includes roads, railways, airways, waterways, canals, and terminals such as airports, railway stations, bus stations, warehouses, and intermodal facilities. Illinois’ centralized geographic location, as well as the diversity of available transportation options, places the Illinois transportation system in an essential role in the nation's ability to move goods and people.

IDOT is responsible for sustaining, strengthening, expanding, and maintaining this system. We do this by partnering with state, federal, and local entities to ensure the transportation network fosters and supports economic growth at the community, regional, state, and national levels. This section of the website showcases information on the Illinois transportation network, how we manage this network, active projects at various phases, research, safety efforts, and much more.
