Transport Infrastructure Ireland cites 2% inflation as Dublin Port Tunnel peak charge hits €14
Motorists will face higher tolls on ten national roads including the M50 and Dublin Port Tunnel from January 1, 2026, Transport Infrastructure Ireland announced today.
The increases respond to 2% inflation recorded in the Consumer Price Index between August 2024 and August 2025, according to TII.
Dublin Port Tunnel
Peak morning charges for southbound traffic through the Port Tunnel will rise by €1 for the second consecutive year, bringing the 6am-10am weekday charge to €14. Peak northbound hours (4pm-7pm) remain unchanged at €12, while off-peak charges hold steady at €3.50 for all vehicles.
M50
All cars registered with tag or video accounts will see a 10-cent increase, as will buses, coaches, and lighter goods vehicles regardless of registration status. Heavy goods vehicles exceeding 10,000kg with tag accounts face a 10-cent increase, while those with video accounts will pay 20 cents more.
Unregistered buses or coaches will pay €4.90, while unregistered HGVs over 10,000kg will be charged €7.80.
National Roads
Eight national roads operated under Public Private Partnerships will see selective increases. On six toll roads—M1, M7/M8, M8, N6, N18 Limerick Tunnel, and N25 Waterford—cars and motorcycles face no increases, though buses, coaches, and HGVs will pay 10 cents more.
The M3 and M4 will see 10-cent increases across all vehicle categories, bringing car charges to €1.80 on the M3 and €3.60 on the M4.
The increases add to mounting cost-of-living pressures facing Irish households and businesses.
