Elbe Crossing 1

Elbe Crossing 1 (center) and 2 (right, one mast only)

Elbe Crossing 1 is a group of masts providing an overhead crossing of a 220 kV three-phase alternating current electric powerline across the River Elbe. Constructed between 1959 and 1962 as part of the line from Stade to Hamburg north, it consists of four masts:

Because of the swampy terrain, each mast's foundation is built on pilings driven into the ground. The Lühesand portal mast rests on 41 pilings and the one on the Buhnenfeld on 57. In contrast to the usual construction of such lattice-steel transmission towers, the direction of the line passes diagonally over the square ground cross section of the pylon, resulting in savings in material. The two crossbeams for the admission of the six conductor cables are at a height of 166 metres and 179 metres. The mast on the Buhnenfeld bears at a height of 30 metres a radar facility belonging to the Water and Navigation Office of the Port of Hamburg. Each portal mast has stairs and gangways for maintenance of flight safety beacons, and has a hoist for heavy loads.

Elbe Crossing 1 was supplemented in the 1970s by Elbe Crossing 2.
