Project

The five tunnel units are placed in the River Shannon, near Limerick in South-West Ireland. The tunnel, which connects Coonagh and Bunlicky, is approximately 900 metres.

The immersion tunnel is part of the ‘Limerick Southern Ring Road Phase II’ project. Ring Road Phase II is the final stage in the construction of a ring road around Limerick City. This ring road will divert a significant amount of traffic away from the city centre.
