In the middle of the
Haringvliet were locks but they weren’t connected with the shores, yet. The south
part of the dam, from the locks to Goeree-Overvlakkee was made simple and
‘fast’. They only had to spout an immense amount of sand on the right place to
erect a dike. The finishing touch was done by lorries and bulldozers. At some places they
gave the dike the appearance of dunes. Making the north part of the dam was more
difficult. the water was deep and more than one kilometer wide. First a cable-railway was
made from the locks to the mainland. From the shore great concrete blocks were transported
and dropped in the water. Each block weights 2500 kilograms. |

blocks were used to make this part of the dam. When these blocks were covered with sand
also the inner holes were filled. Doing this the dam became more stabile. During the
making of these two parts of this dam the gates of the locks stayed open to prevent the
current to grow to an unacceptable strength.
In 1971 this project was finished and for the first time in 14 years all the slides
were closed and the Haringvliet became a lake instead of sea. |
