[edit] Finally opening?

It is being reported in a number of places including here that the tunnel will open in late October/early November. While the city council has not given a final date, the tunnel website has had a significant makeover in the last couple of days. Nelson50 09:02, 14 September 2006 (UTC)

I heard Tim Brick from Dublin City Council say it is likely to open in December. Objection 14:03, 13 October 2006 (UTC)

[edit] Tunnel height

The Sydney (Australia) Harbour Tunnel has only 4.2m verticle clearance, and from time to time a taller truck gets stuck and causes chaos.

Just like the Dublin (Ireland) Port Tunnel to be.

About a quarter of Australian have Irish descent - perhaps that explains things. :-) :-)

[edit] Picture Reqeusts

Hi all, my office looks over the dublin port end of this tunnel, I work in East Point Business Park. Any picture requests for this article, let me know on my talk page. Smitz 20:45, 21 December 2005 (UTC)


Hi,

I haven't been in Dublin since November 2004. I'm eager to know if its nearly finished. Can anyone tell me what stage its at. Have they repaved the M1 at Santry yet?

simon.finnegan@firstdata.com.au

Well, I'm writing in March 2006, and it still isn't finished... Also, I think a map of the route showing it with other main motorways/dual carriageways (M1/M50/N7/etc...) would be good. Jvlm.123 10:50, 18 March 2006 (UTC)

[edit] Map

There's a map here which is already showing the intended route. Why the NRA/DCC etc. are claiming it links to the M50 in 6 minutes, I don't know... it links to the M1, and there's still a good 10 minutes drive (assuming no traffic jams!) to the M50... Bastun 17:08, 23 May 2006 (UTC)

I think the map is wrong - at least for me the arrow is pointing south of stephens green - while the tunnel ends on the northside close to dublin port. this doesn't make sense.
As well it really links to M50 in 6 minutes (I think 3 minutes even is plausible) - there is traffic and it moves slow exactly because the tunnel is still closed - once it opens - the traffic will be... well probably worse, but the M50 is really close to the north exit of it. Dominykas Blyze 20:32, 24 July 2006 (UTC)
Yep, ignore the arrow - dunno where that came from. The tunnel is the one that cuts across Fairview Park in the map, easily visible if you zoom in. I still think the travel times are hugely optimistic. Bear in mind that the tunnel exits onto the M1 in the middle of the road (overtaking lane) - and it's now illegal for HGVs to drive in the overtaking lane, so every truck exiting will have to cross straight away to the driving lane. Chaos. Bastun 22:08, 24 July 2006 (UTC)

The M50 will extend down from the m1 intersection to the tunnel, so the tunnel exits will be the main line, with N1 merging on to it.

When it's finished, the M1 will end at the current M50/M1 roundabout. The M50 will continue from that roundabout south (down the current M1) and into DPT, coming to an end in the north port. I think the figure of 6 minutes is end to end inside the tunnel.

Could the article answer the question why they decided to undertake building this tunnel rather than raise taxes at dublin port so other irish ports could be used?

There's a good map here, and another here. There are different types of maps here. 81.156.237.114 09:55, 22 October 2006 (UTC)

[edit] Correct Conversions to Imperial/US Units

The Tunnel specs have been converted wrong,I'd change but then some people change it back. Either I feel, the imperial should be removed or corrected. Below I made typed the correct figures, based on the 25.4 mm inch / 0.9144 metre yard
