The system opened in 1958 in the Chicago area, and has subsequently expanded to include the eastern and central sections of Interstate 88 (I-88) extending into the northwestern part of the state. Beginning in 2005, the system was reconstructed to include more lanes and open road tolling, the latter of which uses I-Pass transponders to collect revenue as vehicles pass antennas at toll plazas or designated entrance or exit ramps. As of 2017, ISTHA maintains and operates 294 miles (473 km) of tollways in 12 counties in Northern Illinois.

Russell R. Kirt Prairie is a restored tallgrass prairie and savanna within the College of DuPage Natural Areas. A Trail Guide published by the college provides background information and ecological notes. In addition to the mesic prairie and oak savanna, the site also includes a small hill prairie, swale, marsh and wetland areas.: 8 Professor Russell R. Kirt states on the back cover of his book Prairie Plants of the Midwest: Identification and Ecology that he "began restoring prairie in 1974, two years after Ray Schulenberg of the Morton Arboretum introduced him to the prairie". In 1981 he started the restoration project by obtaining grant money from the college's Board Of Trustees, and began collecting native seeds and seedlings from sites within a 40-km radius of the college to ensure local genotypes. In 1984, he reestablished a former farmland and parking lot at the college to prairie with the help of numerous volunteers, including students. The restoration used two methods, either seed broadcast or seedling transplant. Whenever possible, species associations as described by Swink and Wilhelm were planted together. He monitored the site for at least 16 years, and published his findings at the North American Prairie Conference. After 16 years, the Floristic Quality Index (Index Value in Professor Kirt's papers) in areas restored by either method reached about 30, with no significant difference between the two.: 103 The college Board Of Trustees designated the site as West Prairie-Marsh Nature Preserve in December 1993, and renamed it Russell R. Kirt Prairie in November 1999.: 8 The prairie is located less than 100 meters from the college's Health and Science Center, making it the only sizable restored prairie in the U.S. that is within walking distance of a college classroom building, and it is often used for field study by biology, botany, and environmental science classes. The college offers a Prairie Ecology class that focuses on the tallgrass prairie ecosystem, with extensive hands-on studies in the prairie.: 17  Other disciplines that make use of the prairie resource include earth science, art, and photography.

TLC Camp is a privately held 501(c) 3 organization in Illinois, United States that provides a free one-week summer camp for children with cancer and their siblings. TLC (Togetherness in Love and Care) is held annually during the third week of June at Sunset Knoll Park in Lombard, Illinois (TLC Camp 2009). Its purpose is to provide an opportunity for these children to experience a week of fun activities that allows them a break from the rigors of treatment and worry; to enjoy life as a normal child. What separates TLC from other camps of this sort is the inclusion of siblings, who experience the stresses of living with a cancer-stricken brother or sister (Tennison 1993). Extra effort is made to not distinguish those suffering from cancer with those who are healthy. Each year around 100 children ages 5–13 attend the camp free of charge. TLC is run by the Lombard Junior Women’s Club (LJWC), who along with their families and other local volunteers staff the event. Former campers are encouraged to come back as counselors once they are too old to attend (Fellers 2004).
