N8/N25/N40 - Dunkettle Interchange [open to traffic]

The trouble is, there was already an enormous amount of opposition to the bridge you mention. The Mangala Woods bridge it was to be called, people were going apoplectic at the thought of losing the "one last bit of undisturbed wilderness".

Yep but even though it's very unlikely I'd still see mass transit as more a realistic Southside project than the outer Southern Orbital road. I'd actually love if someone had a plan for mass transit to Carrigaline, but I don't think anyone is working towards it at all. It's buses only for the foreseeable future.

Does anyone know what the current night works on the new bridge into Little Island are/were for? It seems like they're ripping up the surface and resurfacing at night?

Why can't the tunnel operator just close one bore at a time and provide a two way flow in the other. The infrastructure and signage to facilitate such an operation is in place and it's a common practice in other tunnels.

Routing traffic through the city centre is a very environmentally unfriendly option. It can result traffic congestion, added journey times plus increased air and noise pollution within the city.

I am not sure if the word rumour is relevant but even if you drive, especially from the Mahon side to the Dunkettle side on a dry day, you will usually see small puddles on both sides of the bore at the deepest part of it.

Has anyone experience of the tunnel in Limerick (N18) it's the same type of construction. How often is it closed.

On one of the few times I used the route one bore was closed and the other had a contraflow in operation.

As I understand it, the sections are covered in silt/earth/etc rather than being purely exposed concrete. Also, the weight of the water would be enormous

The “dúirt bean liom go ndúirt bean léi” water ingress rumours could easily be settled with an FOI request…
