[edit] Photo of new standard exit sign for restricted access roads

Strange looking sign if you ask me. What does "restricted access roads" mean. I presume the number 23 stands for junction 23? Any idea of the clearance? I wonder what the chances are that a large truck travelling in the left lane will strike the bottom of the sign? Ga2re2t (talk) 15:27, 17 November 2007 (UTC)

They are much higher they they look - a tall truck will cream himself at a bridge before getting to one of these! I note the NRA are using the term EXIT for the off-ramps; so this is exit number 23 on the N11 (which will appear on maps as "Junction 23"). "restricted access roads" means you can only get on and off them at junctions like this or at some smaller "left in/left out" junctions - farm gates, field gates, private residents etc cannot access directly onto the road and there are no gaps in the median separating the two carriageways.

A Motorway is an example of a high standard restricted access road but not all roads with grade-separated (flyover) junctions and restricted access are motorways due to lower standards of layout or occasional private entrances that haven't been removed. (talk) 16:05, 17 November 2007 (UTC))

It's a cantilever or half-gantry sign - introduced onto the M50 with the South Eastern Motorway opened, and is the only part of the crazed signage that was piloted on that motorway that the NRA seem intent on retaining (with good reason too, it is probably the only part of the scheme that was actually an improvement). Basically it is the last sign before the exit. So far, its also been erected on the N7 Naas Road, the N2 Ashbourne Bypass (both with the to-be-scrapped dodgey gantries) and on the N11 Gorey Bypass (in the case, regular fork ADSs are otherwise used).

Whether the NRA want to call interchanges "exits" (as in the US) or "junctions" (as in UK) seems to be a matter on ongoing debate (see here for example where the latter is used [1] - while on the N7 and N11 some gore signage has been erected with the word "Exit" and the junction number on it (these signages usually list destinations and road numbers instead). --Rdd (talk) 19:06, 18 November 2007 (UTC)

I think the large EXIT signs are very clear, like the Ausfart signs in Germany (only better). The exit of course is just part of the junction. It will probably be decided by general usage whether the word "Exit" starts to refer to the entire junction, radio stations seem to use both interchangeably. The gantry signs were indeed daft as constructed because they logically implied the slow lane was a filter lane for the exit. But the use of very LARGE junction numbers on the ADS, gantries, cantilever signs, and at the Exit gore (and even on the tourist signs) is an absolutely brilliant feature compared to the crummy little black spots they use in the UK. So, some really good stuff and some really daft stuff in the mix! (Sarah777 (talk) 02:21, 19 November 2007 (UTC))
