As a retired TBTA sgt, I can definetly state that photography IS STRICTLY FORBIDDEN on all bridges & tunnels operated by that agency. This edict has been in effect for many years, but it was not strictly enforced before 9/11/01. It is now. Signs prohibiting "filming" are, (and have been all along) posted at all facilities. Summonses can, & usually will be issued (criminal court "C' summonses) to filmers/videotapers who are seen "filming" on TBTA property (mainly bridges, tunnels and toll plazas, but also in other areas under control of the TBTA). On occasion, arrests result from these filming incidents (suspended motorists, DWI, warrants, etc.) I mention this because for many years TBTA, has been under the control of the MTA. TBTA is still the legal name of the agency (because it is beholden to bond holders, unlike LIRR, Metro North, etc.). It goes under the 'd/b/a" name "MTA BRIDGES & TUNNELS" now. I can't speak definitely for LIRR/Metro North, but it is my understanding that these agencies have no blanket prohibition against "filmers", (unless the situation has recently changed) but don't quote me. Also don't know about NYC subways, but I don't think so. "Cops" would go "nuts" with tourists. Hope this is helpful.[/u]
