Preparations are being made for potential toll points along the M50 in Dublin.
However Transport Infrastructure Ireland insists there are no imminent plans to charge drivers.
It's advertising for companies that would operate the system if the government ever went ahead with it.
The measure is being considered to tackle the ongoing gridlock and tailbacks that commuters face daily.
Other measures being looked at include reducing the speed limit during rush hour.
The AA's Conor Faughnan says extra tolls won't solve the M50's chronic traffic congestion:
"it might be attractive if you want to hoover up toll money, it might also be attractive if you think this is the way to keep the M50 moving - drive traffic off of it - so that the little that's left can move more freely but the issue is what do you do with that displaced traffic, and if all your doing is forcing it into the suburbs then your not actually doing the city any favors"
