Westbound I-64 near the I-255 interchange in Metro East turned into an unplanned construction zone Thursday morning after a truck hit a massive overhead sign overnight, leaving the metal truss folded across the highway. Photos from the scene show two green guide signs sagging so low they nearly kiss the pavement, with their support beams visibly buckled. The Illinois Department of Transportation (IDOT) warned drivers to brace for serious delays while crews work to clear the mess.
According to NBC Chicago, IDOT posted on Facebook just before 8 a.m. that westbound lanes approaching I-255 were closed after a truck struck an overhead sign. The agency added that "our crews are on it" and shared striking images of the collapsed structure, urging drivers to "try to steer clear of the area" as heavy delays piled up.
Damage and cleanup
The photos show the overhead sign assembly crumpled and folded, which means this is not a quick sweep-and-go situation. Crews will need heavy lifting equipment, lane closures and time to safely remove the collapsed steel and repair or replace the damaged supports.
The Federal Highway Administration's Manual on Uniform Traffic Control Devices lays out detailed standards for overhead sign supports and for how traffic must be managed in work zones, a level of regulation that helps explain why swapping out a damaged overhead assembly is often a complex and time-consuming operation: Federal Highway Administration.
Traffic ripple effects
The closure hits a key connector into the St. Louis metro area, so the trouble on I-64 is not staying put. Commuters can expect backups to spill onto nearby routes during the morning rush. IDOT told NBC Chicago that crews were on site, and travelers are being urged to follow official detours and traffic alerts from the state agency. For statewide updates and travel notices, see the Illinois Department of Transportation.
As of this hour, westbound lanes remain closed and officials have not released a timeline for when the roadway will fully reopen. For the latest word on when traffic might get moving again, check travel alerts from the Illinois Department of Transportation for updates and real-time information.
