Lagan Weir, Water control structure in Belfast, United Kingdom.
The Lagan Weir spans across the River Lagan between Queen Elizabeth Bridge and M3 cross-harbour bridge, featuring five metal gates measuring 18 meters by 5 meters.
Constructed in 1994 through a £14 million project, the Lagan Weir marked a significant transformation of Belfast's waterfront development and river management system.
The weir structure connects the docks to the Odyssey complex via a concrete walkway, creating a central meeting point for residents and visitors.
Five independently operated gates control water levels across 4.8 kilometers of the River Lagan, preventing tidal fluctuations and maintaining consistent water depths.
The structure illuminates in neon blue during nighttime, with each gate weighing 32 tonnes and requiring specific operational protocols for boat passage.
