Waterways Ireland wishes to advise all masters of vessels and users of the Grand Canal that the 18th Level is closed to navigation with immediate effect and until further notice.
This closure is necessary following a vehicular strike on Healy’s (Bonynge) Bridge late on Wednesday, 4 February 2026. The collision has caused bridge debris to enter the water and has resulted in damage to the parapet, which pose a significant risk to navigation and public safety. 
Healy's (Bonynge) Bridge, located between Robertstown and Lock 18, Downings South, Co. Kildare: https://maps.app.goo.gl/wfUxtAGqyieeGbNa9
As a direct consequence of this incident, the lowering of the 18th Level and associated works previously scheduled and detailed in Marine Notice No. 14 of 2026 is postponed until further notice.
Waterways Ireland will issue a further update as soon as more information regarding the repair timeline and reopening becomes available. Waterways Ireland regrets any inconvenience caused and thanks canal users for their understanding and cooperation during this unplanned closure.
