Incorrect--if you take one of those bridges/tunnels below 60th street, then stay on FDR or West Side Highway to travel to a different part of NYC (i.e. you never enter the interior surface streets below 60th), then you don't pay the congestion fee.
"The Congestion Relief Zone includes local streets and avenues in Manhattan south of and including 60 Street, excluding the FDR Drive, West Side Highway/Route 9A, and the Hugh L. Carey Tunnel connections to West Street."
