Did you know that this unassuming lock holds a thrilling secret? We stand before the Keersluis Nieuwe Diep a vital part of Amsterdam’s waterways. This seemingly ordinary structure is far more than just a passageway between the Amsterdam-Rijnkanaal and the Nieuwe Diep.
The Keersluis Nieuwe Diep was built between 1937 and 1938. This was a significant project. It was part of the widening of the Amsterdam-Rijnkanaal. The construction wasn’t easy. Instead of traditional pile foundations they used caisson construction. This involved sinking large structures into the ground. One caisson unexpectedly sank slowly into the canal. The ground was softer than expected. Quick digging on the firmer side allowed the engineers to reposition it. The project also suffered a serious accident. A worker fell eight meters. He survived but with a severe concussion.
The Keersluis Nieuwe Diep is remarkably similar to another lock. It is a copy of the Keersluis De Diemen built around the same time. Both locks have three imposing towers. These towers are eight meters tall. Between them are vertical steel gates. These gates control water flow. Twelve wooden beams are also available. They serve as extra protection during emergencies. This detailed design ensured the smooth operation of this important waterway structure.
Notice Bridge 12P adjacent to the Keersluis Nieuwe Diep. This bridge occupies the site of an older structure dating back to 1890. That bridge was built by Rijkswaterstaat. It was part of the Merwedekanaal construction. Engineer J Kluit designed it under the supervision of Chief Engineer JMF Wellan. The new bridge built with the lock is identical to the one at Keersluis de Diemen.
The Keersluis Nieuwe Diep stands as a testament to engineering ingenuity. It also speaks to the challenges and risks involved in such ambitious undertakings. This quiet spot reminds us of human resilience and determination in the face of adversity. It serves as a critical link in Amsterdam’s extensive network of canals. It quietly connects the past with the present. It continues to fulfil its vital role.
