Had to use the Moneygall exit about a month ago. Totally bonkers.

Could they really have saved that much money building these sh**y junctions versus proper merging on/off lanes? I mean, all that tarmac and earthworks around those bends doesn't look very efficient.

Junction 13 on the Limerick to Galway motorway, (i.e. the Tulla Exit on the Ennis Bypass) is crazy, there is no advance warning of the bad corner, or of the speed limit etc. But that is not the bad part, the dangerous part is that the slip lane before the turn is at most 20 meters long, given that it takes 80+ meters to slow from 120kmph to 50kmph at maximum breaking force, this means that you have to slow down on the motorway. This leads to cars behind you either coming right up your tail, or jumping out into the fast lane without looking properly. There is a huge area of land that was used for the site offices for this section of motorway just at the junction, there is no reason for such a short slip lane.
Joining the motor way at this junction is just as bad, there is a 30 meter slip lane to join, so you come around a bad corner at max 40/50kmph, and have 30 meters to get up to motorway speed. Very bad planning

Its very bad considering a lot of these roads were built only a few years ago. Could they not have learnt from other more 'advanced' countries mistakes.

Roads were planned as 100km/h dual carriageways; and exits of that type are quite normal on those - and on German autobahns for that matter.

Just try driving on a Autobahn in germany, most exits were designed 40-50 years ago when most cars were pottering around at less then 100km/h. A lot of them have fairly sharp off ramps

But Ireland's motorways were built not long ago, when a 'slow' car can do 100mph.

They weren't "meant" to be motorways.

A slow car (or any) car shouldnt be doing 100mph though. They build roads and put 100 -120km speed limits on them. If someone decides to exit the motorway at 100mph + and crashes, thats not the fault of anyone but the driver.

never said to do 100mph on a corner, max speed is 100 mph, the new roads should reflect the higher speeds in a modern society compared to old autobahn built for cars at pottering about speeds.

Plenty of trucks tipped over on the exits of m50 for instance due to too tight bends.

For "plenty", read "one".

Have to agree that some of the slip roads on and off the motorway in this country have been designed terribly.

Another slip road were it can be quite difficult to merge on in heavy traffic is the n3 to m50 heading northbound. If you were to only cross were the broken lines are all you have is about 2 and half car lengths, it also narrows very quickly.

The facts are very easily sought, get in your car and drive, tight bends galore in modern ireland.

no last minute decisions here. It's lucky there's a second turn off the far side of ennis. Must have been a issues with the budget on this one.
