BROOKLYN - It may soon be much more expensive for those in New Jersey to get into the city if toll hikes planned by the Port Authority of New York and New Jersey go into effect.

The bistate authority is planning massive fare and toll hikes, sometimes of more than 50 percent on the Lincoln and the Holland tunnels, the George Washington Bridge and other bridges, according to a plan unveiled Friday.

The Port Authority says it is forced to hike tolls for drivers due to the massive cost of rebuilding the World Trade Center. Fares for each bridge are expected to rise by at least $4 next month.
