Nieuwe Meersluis

The Nieuwe Meersluis connects Amsterdam's inner city waterways to the Nieuwe Meer lake. This structure measures about 120 meters in length and nearly 12 meters in width, with roll-up gates to manage vessel traffic.

This lock was built in 1942 to replace the older Overtoomse Sluis from 1808. The new construction became necessary as boat traffic increased on Amsterdam's expanding waterway network.

The lock serves as a passage for sailing vessels with tall masts moving through Amsterdam. Boats taller than 6 meters use this route to navigate from north to south through the city.

The lock operates throughout the day with vessel traffic coordinated through Marifoon radio channels 22 and 69. Boats should contact the lock on these channels to arrange their passage through.

The lock gates are designed to function as a bicycle bridge, connecting the Jaagpad and IJsbaanpad paths. Local cyclists use this crossing daily as part of their regular routes.
