- Two identical carrying masts 189 meters in height, each weighing 330 tons, ensure the necessary passage height of 75 meters over the Elbe. One stands on the island of Lühesand
Lühesand is a small island 1.24 kilometres square in the river Elbe, 8 kilometres east of Stade in Lower Saxony, Germany. The island can only reached by ferry and contains a large camping site, on which many continuous campers stay. The southern carrying pylons of Elbe Crossing 1 and Elbe Crossing...
, the other in the Buhnenfeld on the Schleswig-Holstein side.
Because of the swampy terrain, each mast's foundation is built on stakes rammed into the ground. The Lühesand portal mast rests on 41 stakes and the one on the Buhnenfeld on 57. In contrast to the usual construction of such

s the direction of the line passes diagonally over the square ground cross section of the pylon, which has resulted in certain savings in material. The two crossbeams for the admission of the 6 conductor cables are at a height of 166 meters and 179 meters.
