CALGARY — A contractor was rescued Tuesday after becoming trapped 130 feet in the air, inside a sign above Interstate 55 when a boom lift malfunctioned, leaving him stranded for approximately five hours. The incident happened at the Petro travel center near the Lorenzo Road exit off Interstate 55 in Wilmington, Illinois, where the contractor was performing maintenance inside the station’s 130-foot-tall highway sign.According to ABC7 Chicago, the worker appeared to remain calm throughout the incident and was seen acknowledging people below while waiting for help.Emergency crews responded to the scene but quickly encountered a challenge: their available equipment could not reach the worker’s location.

The worker was not reported to have suffered serious injuries.Authorities have not released the contractor's name and have not said what caused the boom lift to malfunction.
