The new road will link the Limerick Southern Ring Road with the existing Nenagh bypass. There will be interchanges on the route at four locations, namely, Newport, Birdhill, Carrigatogher and Thurles. Bothair Hibernian are the contractors in charge of the project and RPS Scetaroute JV are the engineers overseeing it. The project is being constructed as a 'Design and Build' scheme.
