Dual Carriageways in Ireland (non-Motorway)

theguzman

Only yesterday I realised there is an additional several Kilometres of non-Motorway Dual Carriageway from the M3 at Kells as far as the Cavan border outside, it differs from Motorway as it has the cheeswire dividing wire and roundabouts instead of at grade junctions, sadly on Google Maps etc these stretches of Dual Carriageway are not coloured different to the 1x1 roads when they are superior.

Other examples would be parts of the CastleIsland and Tralee Bypasses, the Tuam Bypass. Can anyone else give examples of these Dual Carriageways? HQDC are built to Motorway standard I understand but not designated as such. How about the Kells to Clonee DC, could that be upgraded to Motorway in future with flyovers and grade separated junctions and replace the cheese wire with the Concrete barrier? I would hope these Dual carriageways are build with future proofing in mind.

Type 2 Dual Carriageway is the TII spec for these. Dromod Roosky bypass was the first of them

Upgrades would be incredibly costly - they are built where upgrades are incredibly unlikely to ever be needed
