Author 'Ghislain' (Id 197907 ) : Here is the boat lift of Strépy-Thieu, a giant 150-metre-high intended to buy only a rise of 75 metres. Finished the many locks ! A monster pharaonic concrete with 2 trays independent of a mind-boggling tonnage to carry boats with a quiet strength to the next level. It is the largest in the world and it took 12 years to build with its environment channels. At its foot, we evaluate our condition of vermisseaux.
