A record of nearly €170 million was collected in toll charges on the M50 last year.
It's almost €30 million more than in 2021 and is also significantly above pre-pandemic levels.
It's nearly nine million more than the previous high in 2019, according to freedom of information figures.
Almost €175 million was collected on nine other tolls last year, according to Transport Infrastructure Ireland.
They show the toll revenue collected on the 10 tolls on motorways and national roads the state agency is involved in.
In total, more than €344 million in tolls was taken in last year, which is over €67 million more than in 2021.
Almost half of last year's income was from the M50, at €169.6 million.
That's a record high and compares to €140 million in 2021 and exceeds the pre-Covid high in 2019, of almost €161 million.
After the M50, the next highest income last year was on the M1 toll in Dundalk, at over €32 million.
That's marginally more than M4 toll at Kilcock-Kinnegad, at €31.8 million.
Aontú TD for Meath West, Peadar Tóibín, is calling for tolls on the M50 to be scrapped.
"Roads like the M50 that have been paid for multiple times over by commuters need to have their toll deleted,
"We've paid well over a billion euro to pay for the M50, so the government is purely using this as a tax on commuters.
"Other tolls that are currently paying for roads, and where the government is locked into contracts, I believe the government should be in negotiations with the companies concerned to see how those tolls can be reduced."
