    I see the problem in part - if you are driving and you have for example a flat/blowout tyre or your engine overheats things like these do happen albeit rarely) you have to stop. Full stop. And stopping in the driving carriageway is rarely a good idea.

    My question is this: would it feasible to add segments of hard shoulder to 2+2 dual carriageways? By that I mean on flat or near flat ground sections, excluding bridges and other areas where the cost would be much higher.

    To be frank...theyre being Muppets.

    The n4 has some truly brutal sections and most are delighted to see the dromod roosky bypass when they finally reach it on a long trip.

    Im sure those in collooney castlebaldwin or anywhere in longford would love a road to that standard. In an era where the n20 goat track exists, those in leitrim should be happy with what their smaller population gets in terms of pieces if the pie

    If you have a breakdown on the 98% of Irish roads without a shoulder you have the same issue.

    2+2 functions well for a variety of reasons.

    1. Breakdowns these days are rare. People should also maintain and check their tyres and cars to make breakdowns less common. Hard shoulders were an idea from an era of very unreliable cars.
    2. The hard shoulder on a WS2 road is 5-6m of fully paved road that is rarely used except for people pulling in to overtake. The 2+2 design is more efficient with use of available tarmacadam.
    3. There is a roundabout in the middle of the Dromod/Roosky bypass, and you can't travel far before being able to get off it.
    4. Future 2+2 schemes with long distances between exits such as the N4 in Sligo will have emergency laybys every 2.5km or so. You'll never be more than 90 seconds from a layby at the speed limit.

    Leitrim CoCo haven't given up - renewed calls for hard shoulder on N4 Dromod/Roosky bypass. "Dangerous"

    they also seem to be focusing on the N16, probably the least trafficed national primary route, and that it doesn't have a hard shoulder for planned upgraded sections , even though the traffic doesnt justify it.

    with the logic that you build way beyond whats needed especially when you're not paying for it, sure why not push to build a full motorway to Enniskillen. Sure they are the safest roads arent they?

    O.T but... That road is under utilised because of its crappiness in my opinion. Road to the second biggest city should definitely get an upgrade. I think it would increase usage a huge amount, not to mention increase Sligos attractiveness for investment,

    If the Sterling is weak it may encourage Sligo shoppers to cross over the border. Might not be welcomed for that reason

    If there's no nearby alternative routes between the towns and villages, and residential access is still provided for, then the 2+2 doesn't allow for any kind of sane pedestrian or cycling use. It would be reckless to even walk to the neighbour's house.

    The contrast with a typical Irish road is that bends and limited visibility and indeed congestion and established driver behaviour when driving alongside a ditch, all these things make a single pedestrian or cyclist less of a sudden and nasty surprise.

    The presence of a second lane completely changes driver attitude into one where overtaking, and therefore max (hopefully at the limit) speed, is effortless.

    Road designs like that need to have space for those going at far lower speeds. For instance, the NRA were forced to close most of the climbing lane on the now R132 in Louth precisely because a stationary car was rear-ended in the non-climbing lane, while waiting to make a right turn. It resulted in the deaths of the occupants of the car.

    There is no 2+2 in Ireland without a viable alternative route at present, or in the future. The 2+2 online upgrade near Collooney will include the construction of a parallel road for pedestrians and cyclists. These days cyclists and pedestrians are taken into account with roads are dualled.
