    Is that the M18's final approach to Rathmorrissy or were the pictures taken near Gort?

    Thanks m17 for updates. Have been following with great interest. Can your quantify how many exits northbound are there going to be between Gort and Tuam and their location?? Thanks in advance.

    Thanks. Not from area so wondering where does one leave motorway between gort and tuam if they want services (coffee/Lunch/petrol). Rathmorirsy/annagh hill do not appear to be close to any town/village!!

    Gort is your best bet unless something newer opens in the meantime.

    A Topaz and Spar(run by Corrib Oil) is less than 30 seconds drive from Gort junction, however it's not 24hr

    Can't be too long now before the final beams are placed - next, the concrete pour on the main overpass bridge and the interchange is topped out! :)

    Can I ask, will the M6 gateway into galway not become horribly congested once the M17/M18 opens?

    Would it be better for someone to exit for say Kilcolgan if coming from the south into Galway?

    http://galwaybayfm.ie/call-facelift-gort-prepares-become-motorway-service-town/
    The County Council is being urged to invest in a major facelift in Gort, as the town prepares to become a ‘motorway service town.’

    Gort is located under 500 metres for the new Gort to Tuam motorway, which is due to open in early 2018.

    Loughrea area councillor Joe Byrne says as a result, there will be no need for service stations along the South Galway section of the new M17/M18.

    He says instead, Gort can be ‘freshened up’ to become a service town on the major route.

    Councillor Byrne says improvements to parking, street-scaping and heritage attractions could bring huge numbers of visitors into the town.

    The intention was for the M6 after J19 to freeflow onto the city outer bypass, as in the N6 GCOB and the M17/M18 would be built in tandem.

    Instead now we have three motorways converging on a roundabout.

    Still handy for north/south N17/N18 traffic avoiding Galway.

    Not much traffic will go north south through this compared to to/from Galway, yet that is the movement that is freeflowing. The issue is more the lack of slips to/from Galway! There are only two missing ones, Galway->M18 and M17->Galway.

    The worrying thing is that the Galway - Rathmorrisey part of the M6 is the ONLY BIT OF ANY OF THE INTERURBANS that is built wide median and can easily accomodate three lanes in each direction. Gives an impression about the amount of traffic anticipated.

    In case we got mixed up, I was on about the roundabout at the end of the N6 Galway-Ballinasloe scheme at Doughiska. All traffic entering Galway along the M17, M18 and existing M6 corridors, as well as the R446 road, will converge on this roundabout.

    Sure at least we can always signalise it.

    Should be interesting to see. Didn't realise it was wide median, can't see it lasting D2M IF the traffic follows.

    Also Rathmorrisey is going to be one crap junction. M17->M6 and M6->M18 should have been freeflow movements

    +1, but in fairness if you take out the traffic involved in the 4 of the flows which are freeflow it probably will work ok.

    Or better put, in morning rush hour the main flows needing to merge will be Tuam-->Galway and Gort-->Galway traffic, where Gort traffic will be free flow and Tuam over the roundabout, and will be by far the biggest amount of traffic on it.
    In the evening it'd be the other way around.

    they could of course have put in a cloverleaf junction, but they are a disaster with heavy traffic like you'd expect in the morning (very tight curve leads to breaking and congestion )

    It looks to me as if the Gort traffic will have to merge into the Dublin/Galway traffic in about 100 metres of merging lane.

    This will be far from free flow, since it will involve 50 km/hr Gort bumblers wandering out into the driving lane, and 100 km/hr Gort BMWs overtaking them, meaning the Dublin/Galway 120+ traffic will be slamming on the brakes to avoid rear-ending them all, with a concertina effect leading to stop-start traffic at rush hours.

    M4, M7,M1 have wide median sections...?

    They were planned as wide median motorways before the interurbans were planned in Transport 21.

    Of the new motorways west of Kinnegad, west of Portlaoise, south of Kilcullen, only Rathmorrissey-Galway was built wide to accommodate a third lane.

    And some of the M8, inexplicably. About 2km near Cahir.

    The rest could lose the hard shoulder for a third lane, if required. Some structures have no shoulder though so it'd be dear

    Yeah I didn't bother mentioning that stretch between the two Cahir junctions because it's only partially between the two junctions (back to concrete nearer the junctions on either side), it's on a stretch where widening is extremely unlikely to ever be required.

    The M18 and M20 have wide median sections also

    The traditional Irish thing to do when a roundabout built in a ridiculous place in the first place becomes over capacity is to put traffic lights on it. Numerous examples in Cork, as well as the M50 (not sure if they were signalised from the start).

    Both were built before the narrow median motorway standard was brought in (N20/21 in 2001 and N18 in 2002)
