Transport Infrastructure Ireland (TII) has announced a series of toll increases across Ireland’s national road network, effective from January 1st, 2026. The changes will impact several major routes, including the M50, Dublin Port Tunnel, and a number of other motorways.

Among the affected routes, M50 users with a tag or registered account will face a 10-cent increase, while heavy goods vehicles (HGVs) over 10,000kg with an account will see a 20-cent rise. The only exception on the M50 will be for unregistered cars without a tag or video account, which will not experience any change in toll rates.
At the Dublin Port Tunnel, the southbound toll during morning peak hours (Monday to Friday, 6am–10am) will increase by €1, rising from €13 to €14. TII stated that “the object of this toll increase is to preserve capacity for HGVs, as non-HGV traffic continued to increase in 2025 during peak periods.”
HGVs and buses remain exempt from tolls at the Port Tunnel, and all other tunnel tolls will remain unchanged for 2026.
Motorists travelling on the M4 Kilcock–Kinnegad and M3 Clonee–Kells motorways will face a 10-cent increase, while goods vehicles on all toll concession roads will also see a 10-cent rise. Additionally, on the M4, HGVs weighing over 3,500kg with four or more axles will be charged an extra 20 cents.
Across Ireland, there are 10 toll roads on the national network — eight operated under public-private partnership (PPP) and two managed directly by TII (the M50 and Dublin Port Tunnel).
TII explained that toll levels are governed by an inflation-linked adjustment mechanism, ensuring that tolls “cannot exceed inflationary impact.” Based on the 2% Consumer Price Index (CPI) increase from August 2024 to August 2025, the toll rates across all routes will rise from January 1st, 2026.
In a statement, TII said:
“The tolling income collected by TII on the M50 and Dublin Port Tunnel is combined with exchequer funding to pay for TII’s annual protection and renewal of national roads.”
It also added that “operation, maintenance and lifecycle costs of the tolled sections of the motorway are funded by tolling income collected by the eight PPP companies.”
