Cape Cod Canal Tunnel

The Cape Cod Canal Tunnel is a fictional tunnel allegedly built in the 1960s under the Cape Cod Canal. It came into popular usage in Massachusetts as a commentary on often severe traffic on the bridges that lead to Cape Cod. It has also been used by locals trying to trick tourists, directing them to a nonexistent entrance near the Massachusetts Military Reservation. The other entrance of the tunnel supposedly exists in New Bedford. Since 1994, decals have been sold in shops around the Cape as popular souvenirs purporting to be "permits" allowing the bearer to use the (non-existent) tunnel; the popularity of these "permits" briefly led to a lawsuit among several different sellers.
