Lock Doesburg was built in the 1950s. Since then, this lock of the Rijn en IJssel Water Board has enabled inland shipping and recreational craft to bridge the variation in the water level of the Gelderse IJssel. After more than 63 years of service, the lock was due for renovation due to wear and tear and exposure to our climate. We have been commissioned by Van Heteren Road and Hydraulic Engineering for a new hydraulic installation for the lock.
