Welcome to the Interstate 55 at Central Avenue Interchange Website!

The Illinois Department of Transportation (IDOT) plans to rehabilitate and reconstruct the Interstate 55 at Central Avenue Interchange. IDOT will begin construction on Friday, September 9. IDOT plans to widen and replace the bridge deck over Interstate 55 to convert the interchange to a single point interchange. This project will include pavement replacement on the ramps and roadways connected with Central Avenue. IDOT will replace traffic signals, install new traffic signals, and improve lighting throughout the project area.

The purpose of the $37.7 million dollar project is to improve safety and ease congestion at Central Avenue and Interchange 55. This project will alleviate the number of accidents throughout the project area and improve access to Central Avenue and Interstate 55.

This site has been created to facilitate public input and provide information about the project and schedule. We invite you to explore the site and provide your comments and concerns regarding the project through our “Contact Us” section.

This site will be updated periodically as the project progresses. The Illinois Department of Transportation (IDOT) wishes to thank you for your support and patience.

UPDATE--September, 2011

The Illinois Department of Transportation (IDOT) continues to work toward a target completion date of Fall 2012. Center piers for the two new bridges that carry traffic over Interstate 55 are scheduled to be constructed this fall. Staging of traffic on Interstate 55 will be installed the week of September 19, 2011, weather permitting. Later this month we anticipate staging of the east Frontage Road just south of existing Arsenal Road to allow grading operation for the extension of Arsenal Road to begin. The road will remain open to traffic during construction except for occasional flagging of traffic to safely move equipment and materials into the work zone. A new section of the east Frontage Road adjacent to the new interchange is expected to be completed in early October 2011.

Staging on Interstate 55 will shift traffic up to 8 feet to the right and close the shoulders on northbound and southbound to provide a work zone for the construction of bridge piers. Two lanes will remain open in each direction. Occasional night time closures should be anticipated for construction activities.

IDOT will continue rock excavation, mass grading, drainage work, construction of retaining walls, roadbed preparation and paving this Fall as weather conditions allow.

The new interchange ramps and bridge structures over Interstate 55 are scheduled to be completed in September 2012.


Did you know work zone fatalities are down 29.6 percent compared to 2003? Aggressive law enforcement and awareness campaigns and significant improvements to work zone safety traffic control reduced Illinois work zone fatalities from 44 in 2003, including 5 workers, to provisionally 30 with 3 workers killed in 2010. So, Give ‘em a brake…slow down for their sake and yours!
IDOT appreciates your patience and understanding as we work to improve the roadways in your community.
