Motorway : 12 km

Between Galway and Limerick, the Atlantic Corridor project aims to provide for a motorway from Tuam, northeast of Galway, as far south as Cork. When the section between Galway and Limerick is complete, the older Limerick to Hurler's Cross section, dualled in the 1980s, will require significant attention to bring it up to motorway standard. The upgraded section would start at the Limerick Southern Ring Road junction. About half of the alignment is fine, only needing a parallel service route, diversion of frontage access to the service route, and closure of the median. The diversion south of Bunratty would need to go offline due to excessive curves. Some of the poor quality grade separated junctions would need work too.

Please take a minute to answer a very short survey on your opinion of this road proposal.

Anonymous from Ireland rates this scheme 5/10 and its alignment 9/10; and reckons the standard is about right. He or she isn't so sure though:
"Not sure if motorway is necessary. Seems to be fine whenever I've driven it."

An anonymous person from the UK doesn't like this scheme. They rate it 1/10 on both counts and reckon it should be lower spec. They have the following blunt comment to make:
"Pointless expense."

An anonymous Irish person isn't too keen either. They rate it 3/10 and 5/10 on the two criteria and reckon it should be lower spec. Their commentary is:
"I think it would be a much simpler fix to run parallel roads along the side of the existing N18 as far as Bunratty to pick up the small side roads that converge on the road and improve the junctions along the bunratty bypass.
This should bring the road standard up to motorway level. it is very much the same standard as the Bray bypass that is designated M11 motorway so there shouldn't be much issue."

Someone from Ireland rates the scheme 7/10 and its alignment 8/10:
"I agree that the section south of Bunratty to the Shannon exits, are not up to motorway standard. One aspect of the N18 in this scheme, not I would like to add is the uneven road surface, which (I think) is due to marsh land that the road is built on. A upgraded M18 north of the current stretch would be a good solution provided the new stretch of motorway can be built away from marshy land areas."

Middle Man from Ireland strongly feels that this should be done, giving it a perfect 10/10 and making this comment:
"Houses fronting onto such a major route at Cratloe is baffling - dangerous access and loss of hard shoulder."
However, he also thinks the standard should be upgraded even further, to D3M (motorway with 3 lanes each way)!

A site visitor doesn't like this scheme, rating it 2/10 and the alignment 1/10. They also think the spec should be higher: "Straighter lines in Setrights X." This refers to this location.

Another gives it 9/10 and the alignment 10:
"Very important, but as there is already a dual carriageway in place, does not need to be done very soon."
