An argument further undermined with statistics that indicate that traffic on the N20 is more than double that on the N5 Galway to Westport leg with the N20 also carrying a proportionally greater number of HGV's.

I would also add that your points on access to Dublin are irrelevant.
Thanks for the link for the traffic stats.
The road between "2nd and third largest cities" had an annual average daily traffic of 10682 (Buttevant and Charleville stretch) in 2019
The road between "two comparatively small towns in the same county" in Mayo had annual average daily traffic 9468 in 2019
Not much in the different really, was surprised how close it was. We need a proper road between Limerick and Cork and it's a disgrace it hasn't been built, but the road between Westport and Castlebar is in worse shape, and need the upgrade.
