A motorist fraudulently sought to hook a free trip across over the George Washington Bridge by rigging up his license plate with a fishing line, but he was reeled in by an alert Port Authority cop, authorities said.

The alleged con job occurred at 7:15 p.m. Wednesday when Javier Marte, 41, was driving his white Freightliner tractor-trailer through the New Jersey-side toll booth through an E-ZPass lane.

The vehicle’s front plate was not visible and the rear plate was curled upward in order to evade the E-ZPass security camera, according to Joseph Pentangelo, a PAPD spokesman.

Marte drove through the toll booth and when a light went on indicating he had not paid his $102 fare, Police Officer George Wkiecinski followed the suspect before pulling him over.

Upon closer inspection, the officer determined that Marte’s front license plate was rigged on a hinge with monofilament, the plastic line used by fishermen, that ran into the cab and ended up on the dashboard of the vehicle.

The apparatus enabled Marte to conceal the front license plate numbers from view by giving the fishing line a tug, only to restore it after exiting the toll and having bypassed any security cameras, Pentangelo added.

Marte, of Yonkers, was charged with tampering with public records, theft of services and possession of burglary tools.
