    There's no issue with speed on motorways in Ireland. Motorways in Ireland have a design limit of 160kph.


    That's some urban myth. I've never come across that. The design speed is 120 km/h. And was always so, even when the speed limit was 70 mph or 113 km/h.

    I don't think we've ever been able to find a reliable reference for the 160km/h figure.

    OK. But what required changes to motorways would be needed to increase it to a design limit of 130kph which is standard in a lot of European countries ?

    the design speed cannot be 120 as safety margins would not allow it. Every engineering project will have minimum margins built in, usually 25-50% when the public are involved. If the design speed was only 120 then you wouldn't be able to easily negotiated corners at 160 on motorways for example as the banking would be all wrong and you'd drift out of the lanes.
