While most people still call the Brooklyn-Battery Tunnel by its original name, it was recently renamed the Hugh L. Carey Tunnel to honor the 51st Governor of New York in a ceremony on October 22, 2012. The above ceremony was attended with much fanfare and included guests such as New York State Lieutenant Governor Robert J. Duffy, Mayor Bloomberg, former Governor Mario Cuomo, MTA Chairman and CEO Joseph J. Lhota, and members of the Carey family.
As with many structures in this city, the original name tends to stick. So while driving you should be looking for signs for the Hugh L. Carey Tunnel, but most often it will still be referred to as the Brooklyn-Battery Tunnel.
