Sixty-one years after introducing toll tickets at its bridges and tunnels, the Port Authority of New York and New Jersey will stop accepting them beginning July 1.

Toll Scrip and Universal tickets will be refunded at their original value.

The PA first issued them in 1951 to improve traffic flow and reduce congestion. Buyers received a 10 percent discount, and the tickets were “good until used.”

But the PA stopped selling them after it started using E-ZPass in 1997.

Instructions for obtaining refunds are posted on the agency’s Web site.
