Hindenburgdamm, Railway causeway in Nordfriesland district, Germany
The Hindenburgdamm is a railway causeway crossing the Wadden Sea in Nordfriesland district that joins the North Frisian island of Sylt to the mainland of Schleswig-Holstein. The track runs parallel to the coastline through shallow water, with tidal flats and channels on both sides.
Construction started in 1923 and took four years as workers poured massive amounts of sand, clay, and stone into the tidal flats. The opening in 1927 ended centuries of reliance on ferry boats to reach Sylt.
Paul von Hindenburg lent his name to the structure when he served as president during its opening, though this association became controversial after 1945. Travelers today watch freight trains and car-carrying shuttles roll steadily across the link that turned Sylt into a year-round destination.
Travelers without cars take regional trains, while drivers must load their vehicles onto special car shuttles since no road reaches the island. The crossing takes about half an hour and offers views of the tidal landscape in all weather.
Currents in the tidal zone shifted after the structure was built, leading to sand loss at the southern tip of Sylt and requiring ongoing coastal protection work. Engineers have monitored these changes for decades and continue adjusting strategies to preserve the island shoreline.
