TRENTON - The New Jersey Senate is ready to vote on a bill to roll back a highway toll increase.

Democrats say the increase isn't needed because it was meant to help pay for a new rail tunnel into New York that won't be built.

Gov. Chris Christie killed the project in October because of potential cost overruns that might have totaled billions. Tolls are still set to go up on the New Jersey Turnpike and Garden State Parkway in January, and the governor says that revenue should be used for state road, rail and bridge projects.

The governor's office also has said canceling the toll increase could affect the Turnpike Authority's borrowing ability. Legislative lawyers say the rollback can be done.

The Senate is scheduled to vote on the issue later this afternoon.
