A piece of the Hudson River is now off-limits for tunnel construction

The Coast Guard has created a temporary "safety zone" on the Hudson River near Pier 66 in Manhattan. This means no vessels or people can enter that area without special permission, to protect workers and the environment during the Hudson Tunnel Project.

Large infrastructure projects often require closing off public spaces, even temporarily. This small, temporary closure is a concrete step in a much larger, multi-decade project to build new rail tunnels under the Hudson River. These kinds of local restrictions are how massive, long-term construction efforts actually get built, piece by piece.
