Peoria County - Route 24 and Illinois 9
PEORIA COUNTY - Proposed expansion includes 8.6 miles of U.S. Route 24 and Illinois Route 9 from Banner to Kingston Mines. Phase I was completed back in the 1990s and final design approval in 2001. Phase II Design Engineering was ongoing from 2001 to 2006 when the project was put on hold due to a lack of construction funding.
The purpose of the project is to improve the operational characteristics and safety of the existing highway facility. The project was determined to be necessary because the existing 2-lane highway has a significant number of crashes lacks left or right turn lanes at side roads/entrances.
Currently re-evaluation of Phase I is happening, and construction should take about four years, breaking ground in 2028 at the earliest (FY2026-2031).
Improvements include the addition of new westbound lanes separated from exiting lanes by a 50-foot median to create a 4-lane divided highway from Banner to Kingston Mines. The additional of two additional thru-lanes and a bi-directional left turn lane to create a 5-lane roadway in Banner with turn lanes at the intersections. Frontage roads will be created to provide access to properties.
On February 11, 2026, almost 95 residents attended an IDOT public hearing in Glasford to gather public input. Generally, most were in favor of the project.
About 79 acres of right of way are needed to complete the project - mostly farmland conversion. For inquiries about land acquisition services, please contact Chad Langan at chad.langan@illinois.gov.
