Travelers at Newark Liberty International Airport can expect a major change in how they move around the airport. A $3.5 billion replacement for the existing AirTrain is under construction, with passenger service expected to begin in 2030.

The project includes a 2.5-mile elevated guideway and three new stations. Designed to accommodate 50,000 passengers a day, the automated system will improve connections between airport terminals, parking areas, rental car facilities and onward rail services. Construction began in October 2025.

For passengers traveling before the replacement opens, however, construction already affects some journeys. Although the existing AirTrain remains in use, portions of its service are subject to temporary closures.

The airport’s published advisory lists weekday suspensions between the Airport Train Station and P4 from 5 a.m. to 3 p.m., running from July 27 through November 13, 2026. Replacement shuttle buses provide transportation during these periods. Travelers should check the airport’s latest service notices and allow additional time when planning their arrival.

The need for a replacement goes beyond the system’s age. Opened in 1996, the current AirTrain carries up to 12 million travelers annually and requires extensive maintenance. The Port Authority says it already operates beyond capacity, and demand is projected to grow by 50 percent by 2040.

The new route is intended better to serve Terminal A and the consolidated rental car facility while supporting the airport’s future development. For passengers, the promised benefits are greater capacity, more dependable transfers, and better connections across a growing airport. The planned opening remains in 2030.
