Transport Infrastructure Ireland (TII) generated a combined €251 million in toll income from the M50 and Dublin Port Tunnel last year, according to its newly published 2025 annual report.
The figure represents an average of €687,671 in toll revenue every day and is a 3% increase on the €244 million generated by the two routes in 2024.
The M50 accounted for the vast majority of the income, generating €216.3 million in toll revenue during 2025. That equates to an average of €592,602 per day and represents a 2% increase on the €212 million collected in 2024.
Of the M50 total, €12.5 million came from penalty income.
TII said the estimated overall tolling compliance rate on the M50 was 97.29%, broadly in line with recent years.
The motorway also recorded its highest traffic levels to date in 2025, with average daily traffic of 161,812 vehicles. There were approximately 59 million journeys on the M50 during the year.
Vehicle kilometres travelled increased by 2% to 1.72 billion.
However, higher traffic volumes and congestion were also linked to an increase in incidents. TII recorded 2,158 incidents on the M50 during 2025, including 818 traffic collisions.
The report states that a significant proportion of the incidents involved minor collisions.
The cost of operating and tolling the M50 was €59.67 million last year.
Toll income from the Dublin Port Tunnel increased by 11% in 2025, reaching €35 million.
Average daily traffic through the tunnel rose by 6% to 28,172 vehicles, while approximately 10.3 million journeys were recorded over the year, a 5% increase on 2024.
Of those journeys, 67% were classified as tollable and subject to charges, while the remaining 33% were non-tollable under the Dublin Tunnel Byelaws.
TII said the cost of operating and tolling the Dublin Port Tunnel totalled €25.43 million.
The report states that around two million domestic and international motorists used the M50 and Dublin Port Tunnel during the year.
TII said net toll revenues, after operating costs, taxes and local authority rates, are invested in the operation and maintenance of the national roads network, helping to reduce the requirement for Exchequer funding.
The report also shows that operating the Jack Lynch Tunnel in Cork cost €5.99 million in 2025, down from €6.34 million the previous year.
Across the motorway network, 71.3 million tolling transactions were processed through the Tolling Interoperability Management Platform during 2025. These transactions had a combined financial value of approximately €254 million.
Overall, 151.94 million trips were recorded across the National Roads Network, excluding Eastlink, representing a 3% increase on 2024.
TII's legal costs more than halved during the year, falling from €739,000 to €305,000. A further €89,000 was recorded under settlements, which TII said were paid by its insurers.
TII also has responsibility for the Luas, which carried a record 55 million passengers in 2025.
In March, TII and the National Transport Authority awarded a new seven-year, €1.3 billion contract to KeolisAmey to operate the Luas. The contract includes additional peak-time services from 2027 and provision for the Luas Finglas extension.
KeolisAmey is due to take over operations on September 1, 2026, with the existing operator, Transdev, facilitating the transition.
TII's overall spending increased by 9% last year, rising from €1.76 billion to €1.9 billion.
The organisation received €1.7 billion in State grants, including €1.48 billion for the national road network, €187.5 million for Light Rail and MetroLink, and €40.3 million for administration.
