The entirety of the NYS Thruway system is under control of the NYS Thruway Authority, including the TZ Bridge. Policing is done by NYSP Troop T, which is not a regular NYSP Troop, but is instead exclusive to the Thruway system. They are NYS Troopers, but operate under the NYSTA's authority and control.
