In January 2019, New Jersey Governor Phil Murphy announced a plan for a $2 billion replacement project for the Newark AirTrain. Murphy has stated that replacement is necessary because the system is reaching the end of its projected 25-year life and is subject to persistent delays and breakdowns. The Port Authority would be responsible for funding the project. In October 2019, the Port Authority board approved the replacement project with an estimated cost of $2.05 billion. Construction is expected to start in 2021 and be completed in 2024.
