On June 21, 1970, the Toledo, Peoria and Western Railroad Company's Train No. 20 derailed in downtown Crescent City. A propane tank car ruptured, and explosions caused fires that destroyed the city center, which included numerous houses and businesses. There were no deaths, although over 60 firefighters and civilians were injured. The disaster would later be featured on episode #124 of the Discovery Channel show Destroyed in Seconds.

In 2009, Crescent-Iroquois High School, the main high school for the village, was shut down. This meant that the elementary school would have to send the graduating 8th graders to surrounding high schools. The building was then used for special education purposes until around 2019, when they transferred them to Gilman, Illinois. In May 2022, the board of education accepted for the building to be demolished. The class of 2023-2024 was the first K-5 institution of the elementary school, after the 6th-8th grade classes were repurposed.
