The Tappan Zee Bridge's cashless tolling facility goes live on Saturday.

The state-of-the-art facility is located on the southbound New York State Thruway in South Nyack. Its gantry has been under construction for months.

Once activated, drivers won't have to slow down or stop at the toll plaza in Tarrytown, which is good news for drivers with or without E-ZPasses.

For those who have E-ZPass, the toll is collected using the same process. For drivers who don't have E-ZPass, cameras will photograph a car's license plate as it passes under the gantry. A bill will then automatically be sent to the driver.
