Dublin's apparently blocked HGVs since 2007.
"The HGV Strategy provides for a ban on 5+ axle vehicles during the hours of 07.00-19.00 seven days a week from a designated cordon area and provides a limited permit scheme for 5+ axle vehicles that need to load/unload within the city centre area."
"The HGV Strategy has resulted in dramatic reductions of 5+ axle vehicles within the city centre area of between 80 - 94% on different routes within the cordon area. "
I don't know enough about HGVs to know if the ones we see around are more than 5 axles. Suspect they may not be. So perhaps an equivalent ban here would not make much difference?
