根据Passage du Gois上的描述
“Running almost three miles across the Bay of Bourgneuf, the Passage du Gois is built atop a narrow spine of silt that has developed over hundreds of years. Eventually the line grew big enough that it rose out of the waters during low tide, creating a land bridge across the bay.“

“The history of the Passage du Gois
People went on foot over the sand-banks to the island of Noirmoutier. Much later they have made a paved road. In those days a lot of accidents took place on the Passage du Gois, because of the quickly rising water was underestimated. This is the reason why rescue poles have been built. Anyone who is surprised by the rapidly rising water or a breakdown of the car can climb in one of these rescue poles. The last strengthening of the causeway took place in 1924.“
以及 Passage du Goi 上的描述
“The stone paved causeway was first used during the 16th century and is still used daily by tourists and locals. At high tide the road lies under 1.5 - 4 metres of water.“
