The E-ZPass Interagency Group (IAG) was formed in 1990 with three states (New York, New Jersey & Pennsylvania) and seven agencies (Pennsylvania Turnpike, Port Authority of New York & New Jersey, New Jersey Turnpike, Garden State Parkway, MTA Bridges & Tunnel, New York State Thruway, and Atlantic City Expressway). The first deployment of E-ZPass was on the New York State Thruway at the Spring Valley barrier on August 3, 1993. The IAG currently has over 10 million account holders who utilize more than 18 million transponders operating electronic toll collection for 24 agencies in 14 states. The ten million account holders reside throughout North America with thousands in each state and province including the States of Hawaii and Alaska. Today twenty-four member agencies operate E-ZPass on 48 roads, bridges and tunnels in the Northeast and Midwest. These members are growing monthly.
