If you travel on the new road between Athlone and Dublin — now with all the towns bypassed (thankfully) — there are no service areas at all unless you divert off the route. When the new route was being built, the National Roads Authority should have been obliged to provide service areas at various intervals. There are a few lay-bys but no toilet facilities or nowhere you can even stop for a cuppa. This is disgraceful.
I think the NRA announced a few years back that they designed the roads without services as these were seen as one of the primary accidents points, I guess they were really trying to get people to exit for the nearest town and do the business there.
I think the morotways in France are great lots of rest areas and playgrounds for the kids, we really need to follow their lead.
