Originally the PGBT was equipped with traditional toll plazas for cash payment as well as RFID-based TollTag express lanes. However, on July 1, 2009 the cash plazas were closed and replaced with "ZipCash", an OCR-based camera system which reads the license plate and bills the owner by mail. This made the turnpike the first in the United States to transition to all-electronic toll collection. The ZipCash rates, however, come at a premium being significantly higher than both the TollTag rate and the earlier cash prices.
