How did the Dublin Port Tunnel improve links between Dublin Port and Ireland’s motorway network?

The Dublin Port Tunnel, which opened in 2006, serves as a vital piece of infrastructure for the city. As Ireland’s largest civil engineering project, it directly connects Dublin Port to the national motorway network. By providing this dedicated link, the tunnel facilitates the efficient movement of freight and traffic, bypassing the city center and improving overall connectivity between the port and the rest of the country.1
