The Chicago Department of Aviation (CDA) has temporarily closed 6,445-foot Runway 4R/22L at Midway International Airport (KMDW) due to necessary repairs to the engineered materials arresting system (EMAS) at the departure end of 22L.

EMAS uses beds of lightweight, crushable material—such as cellular cement or foamed silica/glass—that slows an airplane overrunning the runway and brings it to a safe stop. According to authorities, the EMAS on 22L sustained damage from recent aircraft activity, including jet blast. The work is expected to last for three weeks, with an anticipated reopening on November 13.

“Safety is the top priority at Chicago’s airports, and we are working to complete these repairs safely and promptly,” said CDA commissioner Michael McMurray. “We’re coordinating closely with our partners at the FAA and the airlines to reduce disruptions for travelers and return the airfield to normal operating conditions as quickly and safely as possible.”
