How does the Chignecto Isthmus connect New Brunswick with Nova Scotia?

The Chignecto Isthmus serves as a narrow neck of land that connects New Brunswick to Nova Scotia and the rest of the Canadian mainland.12

Located in the center of the Maritime Provinces, this isthmus spans approximately 15 miles (24 km) at its narrowest point. It physically separates the Northumberland Strait to the north from Chignecto Bay, which is a northern extension of the Bay of Fundy, to the south. By bridging these two bodies of water, the landform creates the vital terrestrial link between the two provinces.12
