Waterways Ireland advises masters of vessels on and users of the Shannon Navigation that the Gaelforce Great River Swim will take place between Tarmonbarry and Ballyleague next month.

Around 500 swimmers will participate in the swim event in Lanesborough on Saturday 18 May.

The Shannon Navigation between Tarmonbarry lock and Ballyleague bridge will be closed on the day between 9am and 2pm. Tarmonbarry lock and Cloondara Canal lock will also be closed and vessels will be prohibited from proceeding upstream from Ballyleague bridge during thus time.

A series of large bright green and red buoys branded with Gaelforce will be positioned along the swim route on the evening of Friday 17 May and will be removed after the swim on Saturday 18 May, the cross-border body for Ireland’s inland waterways says.

Waterways Ireland advises masters of vessels on and users of the Shannon Navigation that the lifting bridge at Tarmonbarry in Co Roscommon will now reopen on Friday 3 May.

This extension of the bridge’s closure since February is a result of additional repair works required following a bridge strike.

The cross-border body for Ireland’s inland waterways says it apologises for extending this closure “but the additional work is essential to ensure the bridge is safely operational in advance of the bank holiday weekend”.

A diversion route remains available via the Camlin River.

Waterways Ireland advises masters of vessels on the Shannon Navigation that in-river works for the construction of the Killaloe Bypass upper bridge superstructure are progressing as planned and will continue until October 2024.

As previously reported on Afloat.ie, the bridge is being constructed around 1km downstream of the current Killaloe–Ballina bridge.

A buoyed navigational channel continues to be provided for 100 metres either side of the in-river works.

The following plant and equipment will be operating on or overhead the navigation during the upper bridge works:

• 600t crawler crane set up on the east shore
• Stabilising crane barge (30m x 23m x 1.88m)
• 100t crawler crane
• Tugboat/pusher boat
• Dumb barge (23m x 9m) and mobile elevated work platforms
• Safety boat
• Landing pontoon and gangways

From next Tuesday 2 to Friday 19 April, the final steel girders will be lifted into position in the central spans of the bridge.

This is a heavy lift operation and deemed high-risk work, requiring calm waters for operation of mobile elevated work platforms (MEWP) on barges.

Masters of vessels are requested to proceed at slow speed (5 knots, no wash) with additional caution in the vicinity of the works, and to follow the instructions of the safety boat crew as there are hazards such as bridge piers, steel piles and mooring lines to navigate.

The cross-border body for Ireland’s inland waterways thanks its customers for their cooperation in relation to these works.
