Limerick City & County Council [why don’t they shorten it to Limerick Council?] is examining options for an improved road from Limerick to Foynes, which is the main port on the Shannon Estuary. The options are set out on this website and you can download a PDF map that makes it easier to see the details.
The Red Route would cross the Deel Navigation just below Askeaton: the existing route does the same so there might not be any extra interference with the navigation. But the Red Route would also cross the Maigue and the Blue Route would do so just below the new quay at Adare. No doubt the Adarians would welcome a bypass but I imagine that the Office of Public Works will be watching to ensure that navigation on the Maigue, for which it is still (as far as I can tell) the navigation authority is not impeded.
Meanwhile we learn that some folk and some other folk want the railway line from Foynes to be reinstated. I have no idea why they think that’s a good idea: it’s not as if there were vast piles of incoming freight piled up at Foynes, unable to be shifted by road. Rip up the tracks and make a greenway, that’s what I say.
