and the site of a World War II coastal fortification. Bournedale Hills Trail extends along the north side of the Canal from Bourne Scenic Park campground to the Herring Run. The trail includes a self-guided loop which interprets the Canal's historic and natural features. Tunnel folklore and proposal A spoof became popular during the late 20th century concerning a fictitious road tunnel, allegedly built in the 1960s, under the Cape Cod Canal. It came into popular usage in Massachusetts as a commentary on the severe traffic entering and exiting Cape Cod during the summer months. Since 1994, decals have been sold in shops around the Cape as popular souvenirs purporting to be "permits" allowing the bearer to use the tunnel; the popularity of these "permits" briefly led to a lawsuit among several different sellers. In 2019, the Massachusetts Department of Transportation (MassDOT) indicated that it had studied the idea of adding a tunnel to help alleviate traffic, but due to findings it would not presently consider moving forward.
