- A steel footbridge crossing the new barrage and connecting the right bank to the island where the new barrage control building is sited. 

Equipment upstream:

- Construction of a bulkhead-gate storage area (island side)

- Extension of training wall to upstream tip of island

- Cable laying by boat.
