Staustufe Höchst, Barrage in Höchst district, Frankfurt, Germany

Staustufe Höchst was a lock and weir installation on the left bank of the Main just above the Höchst ferry, where the river turns northwest before the Nidda mouth. Its 300-metre canal, 20 metres wide at the bed and 2.50 metres deep, held a chamber 101.40 metres long with a clear width of 10.50 metres and a usable length of 85 metres. Beside it stood a needle weir with two openings of 59 metres each, a 12-metre timber float channel and a fish ladder.

The structure was built between 1883 and 1886 and operated until 1932, when the Griesheim dam upstream took over its functions. It was central to river navigation along the Main for decades before being replaced.

The former lock keeper's house on the Schwanheim bank tells the story of workers who once managed river traffic here. It reminds visitors of how important this place was for moving goods through Frankfurt.

The former lock lies on the left bank of the Main just upstream of the Höchst ferry crossing, where the river turns northwest before the Nidda mouth. The lock canal was filled in after 1945, so only the old lock keeper's house on the Schwanheim bank remains; it stands on a raised mound safe from floods and is still inhabited. The banks on both sides belong to the Frankfurter Grüngürtel protected landscape.

During construction, a wooden barge loaded with bricks was driven by the current against the finished central pier and sank. Recovery attempts failed, so sappers of Pionier-Bataillon 21 from Mainz-Kastel blew up the wreck with powder and dynamite; the pier survived undamaged.
