Each day the Illinois Department of Transportation (IDOT) strives to design and maintain a world class transportation system that enhances safety and the quality of life of its citizens and visitors by reducing congestion and increasing mobility. This transportation network also facilitates and improves the inter-connectivity of all transportation modes for the efficient movement of people and goods to support the state’s national and global competitiveness.
IDOT’s roots can be traced back over a century dating to the first cars and dirt roads. Its rich history spreads across the entire state. On each mile of interstate and railroad the mark of the Illinois Department of Transportation can be seen and felt.
Over the past century, Illinois businesses, residents, and visiting travelers have seen the steady development of one of the largest and most effective multimodal transportation systems in the nation including roadways, passenger and freight railroads, transit and commuter services, bikeways, airports, water ways and canals, port districts and inter modal facilities.
In the last fifty years, Illinois’ geographical location near the center of the nation and the diversity of statewide transportation options have made the Illinois multi-modal network a keystone and vital hub for national and regional travel and freight movement.
IDOT’s talented, professional and diverse public servants understand the importance of innovation, stewardship and collaboration. They work every day to ensure that Illinois citizens and goods reach each destination in the safest, quickest, easiest, and most cost effective manner.
