FORT LEE - The unannounced lane closures in September that backed up traffic on the George Washington Bridge has cost a Port Authority official his job.

David Wildstein says he intended to leave next year, but has decided to resign earlier because of the Fort Lee issue.

Officials say the unannounced lane closures were part of a traffic study. They have denied that the closures were politically motivated.

Reports say that Wildstein, the Port Authority's director of interstate capital projects, was appointed by Gov. Chris Christie and was one of his chief allies at the agency.
