Newark Liberty International Airport’s main runway, 4L/22R, is back in operation after a major rehabilitation project finished 13 days ahead of schedule, federal and state officials announced this week. The early reopening is expected to help ease recent congestion and delays at one of the nation’s busiest airports.
The $121 million project began in early March and required a full shutdown of the 11,000-foot runway starting April 15. Originally scheduled to reopen on June 15, the runway is now open for departures as of June 2, with full arrival operations expected to resume after final safety checks in the coming days.
Officials credited the accelerated timeline to expanded work shifts, additional construction crews, and continuous 24/7 operations.
The Port Authority of New York and New Jersey (PANYNJ) also brought a second asphalt plant online to double paving capacity, helping crews complete critical upgrades that included new pavement, updated lighting, improved airfield signage, new underground electrical systems, and enhanced drainage.
“It took around-the-clock work — literally seven days a week of people, multiple crews, paving, milling, electricians, and Port Authority aviation, operations, maintenance and engineering staff to make this happen,” said Sarah McKeon, Port Authority aviation director.
For now, the reopened runway will only be used for departures while the Federal Aviation Administration (FAA) completes final navigational aid tests and safety verifications.
The airport’s maximum arrival rate remains capped at 28 aircraft per hour until these checks are complete, after which the rate will increase to 34 arrivals per hour.
The closure of runway 4L/22R since mid-April had forced Newark Liberty to operate with just two runways, resulting in significant delays and a 15% reduction in arrivals and departures.
United Airlines, the airport’s largest carrier, and other airlines had to cut back schedules during the construction period. Officials expect the early reopening to bring immediate relief to passengers and airlines, with increased flight schedules set to resume by mid-June.
While the main phase of rehabilitation is complete, officials noted that runway 4L/22R will continue to be closed on weeknights and weekends from September through December to finalize the project. The Port Authority emphasized that these closures are necessary to ensure the runway meets the latest FAA safety and design standards.
The runway project is part of a broader multi-billion-dollar investment in Newark Liberty’s infrastructure, including recent upgrades to terminals and taxiways. However, airport officials and the FAA acknowledged ongoing challenges, such as air traffic controller shortages and technical issues, which have contributed to recent disruptions.
Transportation Secretary Sean Duffy praised the collaborative effort, stating, “We don’t want to rush anything, doing it the right way is key, so that you feel the system is safe and we know the system is safe”.
Travelers are advised to check with airlines for the latest flight information as Newark Liberty transitions back to full runway capacity.
