Tolls are going up on New Jersey's two main highways. Starting Monday, the cost of an average 22-mile trip on the New Jersey Turnpike will rise from $1.25 to $1.70. One-way tolls on the Garden State Parkway will go from 35 to 50 cents. Electronic message boards on both toll roads are reminding drivers about the upcoming increases. The additional revenue will be help fund future construction and will also be used to repay bonds sold to pay for past projects. Three new lanes are planned for the Turnpike between Exits 6 and 8A, and a third lane will be added to the Parkway between Exits 63 and 80.
