Sluiscomplex Heumen, Lock complex in Heumen, Netherlands
Sluiscomplex Heumen connects the Maas River to the Maas-Waal Canal using two separate lock chambers. The larger chamber measures about 145 meters long while the smaller one is around 120 meters, allowing different types of vessels to pass through.
Construction began in the 1920s and the lock was completed when the Maas-Waal Canal opened at the end of 1927. This infrastructure project improved transport connections across the region.
A memorial near the pumping station honors those who died in World War II battles around the lift bridge. This monument reflects how the place connects to broader historical events that shaped the region.
The lock operates around the clock every day, and boat operators can contact staff using maritime radio channel 22 or by telephone. It helps to check current conditions before passing through, as weather and water levels may affect operations.
The two lock chambers have different height restrictions: the inner lock allows vessels up to 4.80 meters tall while the outer lock limits passage to 4.60 meters. These differences determine which boats can use each route.
