CASEYVILLE, ILLINOIS — Interstate 64 reopened in both directions at I-255 in St. Clair County Thursday afternoon after a tractor-trailer with a raised dump bed struck an overhead highway sign in a construction area, bringing the sign and its truss down across four lanes of traffic and triggering a more than 13-hour closure.
The incident occurred at approximately 11:45 p.m. on Wednesday, April 9, on westbound I-64 approaching the I-255 exit near Caseyville. The tractor-trailer was leaving a construction site with its dump bed still raised when it struck the overhead sign. The impact damaged a support structure, causing the sign and truss to collapse onto the roadway. All four lanes were blocked. No injuries were reported.
The Illinois Department of Transportation closed the interstate through the overnight hours and into the afternoon rush. The highway reopened at approximately 1 p.m. Thursday. The closure stretched through the morning commute and caused miles-long backups, adding up to an hour to some drivers’ commute times.
No further details about the driver or construction company have been released.
