Kiewit Corp., the big contractor leading one of four teams seeking the prime contract for the planned $2-billion AirTrain monorail replacement at Newark Liberty International Airport in Newark, N.J., has dropped out of the competition, according to a source familiar with the matter.
The Port Authority of New York & New Jersey, the project's owner, has not separately confirmed the withdrawal. Nor is it clear whether other members of Kiewit’s team, called Liberty Mobility Express, played a role in the contractor's decision to exit.
