The 675m tunnel under the River Shannon is one of the largest and most complex infrastructural projects ever undertaken in Mid-West Ireland.

RPS, in a joint venture with COWI, has fulfilled the role of Project Consultant since 1999 and has worked with its JV partner, Limerick County Council and the National Roads Authority (NRA) on delivering this key piece of infrastructure that forms a critical link in the Government’s proposed Atlantic Corridor on the west coast of the country.

The tunnel, which is the fourth crossing of the River Shannon, will reduce journey times for traffic crossing the River Shannon, reduces traffic volumes moving through Limerick City, improves interconnectivity between national routes converging on Limerick City and improves access to Shannon Airport. It will deliver both economic and environmental benefits for the local community by easing traffic congestion in the city and reducing journey times. The reduced traffic congestion in the city will improve safety for both motorists and pedestrians and will facilitate increased the use of bus and cycle lanes in the city, while improving air quality by reducing emissions.
