Dublin City Council's announced new fares for crossing the Tom Clarke Bridge (formerly known as the Eastlink bridge).
It's after an EU settled the long running row over whether drivers should be charged VAT to travel over the Liffey from The Point to Ringsend.
The European Court of Justice ruled that tax should not apply to tolls that are collected by the state.
It means from next Friday the 18th of August, ordinary motorists will only be charged €1.40 instead of the former rate of €1.70.
Here's the breakdown for commerical vehicles:
Van/Bus €2.60 €2.10
2 Axle €3.50 €2.85
3 Axle €4.30 €3.50
4 Axle €5.20 €4.25
The Consumer Association of Ireland is welcoming the decrease but says it means motorists have been overpaying for years.
Deputy chairman Michael Kilcoyne says he doesn't know how consumers will get their money back.
"Well money was collected from them that shouldn't have been, so it doesn't belong to those who collected it; put it that way. It would appear the shame principal should applied to other tolled roads."
The Dublin Chamber of Commerce is welcoming the cut but is calling for the reduction to apply to the Port Tunnel too.
The business group also believes the two fares should be integrated so that drivers don't have to pay twice to by pass the city centre.
"The opening of the Luas Cross City extension means that it is about to become much more difficult to drive through Dublin city centre. This will result in people having to use alternate routes. Therefore, it is important that we make it easier and more attractive for people to drive around the edge of the city centre. The reduction in toll prices will encourage more people to use the East Link bridge and also the Port Tunnel."
