(Springfield, IL) -- There have been more than 130 accidents in the I-55 construction zone near Channahon in the past year-and-a-half. IDOT reports seven people have been killed in the work zone, even though it has some of the most advanced safety measures in place. They include reduced and extended work zone speed limits, signs alerting drivers of upcoming construction, and rumble strips were put down last week after five people were killed. Drivers have an option to take a detour off I-80 and Illinois 47 to avoid the area. Work is tentatively set to wrap up in August.
