# Harlesiel sluice adaptation and replacement rolling bridge

Sielacht Wittmund seeks works to adapt the Harlesiel sluice to higher design water levels and replace a single-lane rolling bascule bridge. The scope includes removing the existing sluice-building roof, adding a third floor and control station, removing the existing lift gate and pair of flap gates, and installing a new steel lift gate with drive and counterweight plus a new gate pair. The complete structure, including demolition, civil, masonry and hydraulic-steel work, drives and equipment, must be made operational as one system. No deadline or value appears in the available description.
