Choi, 62, of New Springville, was struck by a car on Oct. 20, 2013 while reopening the Brooklyn-bound lower level of the Verrazano-Narrows Bridge to traffic. He suffered severe pelvic and head injuries and remained comatose at Staten Island University Hospital until he died Monday morning.
He became the first Bridges and Tunnels officer to die in the line of duty in the history of MTA Bridges and Tunnels, which was formally known as the Triborough Bridge and Tunnel Authority.
Choi joined the MTA on Jan. 27, 2003, and was assigned to the Verrazano his entire career.
In 2006, Choi received a meritorious service award for a felony arrest at the bridge of a motorist driving with a license that had been suspended 179 times.
While being transported to a local police precinct the motorist tried to escape and Choi subdued him.
Choi, a 10-year veteran MTA officer, suffered severe pelvic and head injuries after a Nissan Maxima struck him as he dragged a safety barrel off the roadway on Oct. 20, 2013, authorities said.
Never regaining consciousness, he was later transferred for long-term care to Seaview Rehabilitation Center. Choi was recently brought back to University Hospital, where he died Monday morning, according to the MTA.
He is survived by his wife, Michelle, two sons, Calvin and Timothy, and daughter, Tiffany.
