Road network Map?

    I'm looking for a Google Maps/OpenStreetMaps service that actually visually indicates the difference between dual-carriageway and single lane national routes, in order to plan a route. Anyone know of one?

    Thanks Enbee, if you don't zoom in to below 20KM they show that the Enniscorthy and New Ross bypasses are all done. Wish it was that quick ;-)

    The only bits of Dual carriageway not connected to the motorway network are the
    N4 Sligo to Colloney
    N4 Roosky/Dromod bypass
    N13 Letterkenny to N14 junction
    N2 Castleblaney Bypass
    N21/23 Castleisland bypass

    That wasn't the question though :)

    The Michelin map thing works well though!

    Not really a dual carriageway, is it? 2+1 seems to be classed separately.

    Agree.
    But so also.is the N2 Castleblayney bypass.
    2+1 is classified as Type 3 Dual Carraigeway.

    (Type 1 is 2x 3.5m running lanes + 2.5m hard shoulder either side + concrete barrier, all junctions full/compact GSJ,
    Type 2 is 2x 3.5m running lanes + 0.5m hard strips + wire barrier, junctions compact GSJ/at grade roundabout,
    Type 3 is the 2+1, which seems to vary but mainly 2 lanes in one direction and 1 in the other alternating every 2km, with hard shoulder on the '1' side and junctions can be anything from at grade junctions to compact GSJs)

    Type 3 dual carraigeways in Ireland would be:

    N2 Castleblayney BP
    N20 Mallow - Rathduff
    N24 Piltown BP
    N24 Cahir BP

    The N4 Dromod-Roosky BP along with a host of others were planned as Type 3/2+1 but opened/in planning as 2+2 now.
