Christie's chief of staff when the bond documents were changed to include questionable language referring to the Skyway. In December 2014 United Airlines filed a complaint with the Federal Aviation Administration that claims that since 2004 the PANYNJ has diverted more than $2 billion from the metro area airports to non-airport uses and that in 2014 alone it spent $181 million to repair the Pulaski Skyway and $60 million on the Wittpenn Bridge, NJDOT owned and operated structures. Fort Lee lane closure scandal On September 9, 2013, two of three dedicated toll lanes of the Fort Lee entrance to the upper level of the George Washington Bridge (GWB), operated by the Port Authority of New York and New Jersey, were closed without notification of municipal government and police officials. The lane closings caused traffic jams leading to major delays for school transportation and police and emergency response within Fort Lee, both during and after the peak hours of travel.
