Transport Infrastructure Ireland (TII) is recommending higher rush-hour tolls for Dublin’s Port Tunnel to reduce the use of the tunnel by private motorists during peak periods. Multiple outlets report that internal discussions within TII identify a sharp growth in the volume of “tollable” traffic using the tunnel, particularly traffic that appears to be avoiding heavy morning congestion on surrounding roads. RTE reports that the number of cars using the tunnel is rising rapidly enough that transport officials believe toll adjustments are needed to discourage some drivers from choosing the tunnel at rush hour. BreakingNews.ie and TheJournal.ie add further detail, saying TII’s internal material attributes the trend to vehicles seeking to bypass morning traffic and estimates that the volume of tollable traffic is increasing by more than 8% per year. The proposal is framed as a demand-management measure, aimed at influencing driver behaviour during times of highest congestion while keeping the tunnel in use for those who need it. The reports describe recommendations being discussed by transport chiefs rather than a fully implemented change.
