In consultation with the Federal Aviation Administration (FAA), the Chicago Department of Aviation (CDA) announced on Monday the temporary closure of Runway 22L at Midway International Airport to arrivals and departures for repairs to a runway safety system. The closure is effective immediately, and repairs are currently targeted for completion in mid-November. The Engineered Materials Arresting System (EMAS) at the departure end of Runway 22L sustained damage from recent aircraft activity, including jet blast, necessitating the repairs. The closure has the potential to cause flight delays and cancellations. The extent of these disruptions will vary based on airline schedules and weather conditions, particularly wind direction, which affects how the airport’s four-runway network can be used for arrivals and departures. Travelers should monitor their flight status and check with their airline before heading to the airport. Passengers whose flights are affected should work directly with their air carrier on rebooking or other itinerary changes. CDA will coordinate closely with the FAA and airlines operating at Midway to minimize operational impacts whenever possible. The department will keep travelers and airport partners informed throughout the repair process.
