Reply To: Irelands Ten Worst Roundabouts
I agree that in particular places roundabouts are the ideal solution. The example of the Kilkenny ring road or somewhere like Castlebar.
But for junctions between motorways and very busy dual carriageways they do appear less than optimum in their capacity provision.
Add this the Irish solution to an international problem one gets the roundabout with traffic lights. Chaos is what results when you combine traffic lights with Roundabouts.
To make the Country’s main dual carriageways enter roundabouts with traffic lights to cross a ring motorway was not well thought out.
To run a tram system through an already congested roundabout was even worse.
To build some of the biggest retail developments beside these already inefficient hybred junctions is even worse again.
