From 2006-2010, the M50 underwent a thorough overhaul. Major junctions were freeflowed and minor diamond-style ones were doubled in capacity. However, since the junction with the N81 isn't nearly as important as the ones with other national routes, it only received modest improvements - the addition of some left-turn slips. Inevitably, more will be needed going forward, with the relentless growth of Tallaght as a major suburb of Dublin. Also, if this proposal to connect the N81 with the M7 west of Naas is built, far more traffic will use this junction than at present.
The proposal is to free-flow the junction in the same manner as was implemented for the N2, N3, N4 and N7 interchanges with the M50. The pedestrian bridge passing through the area is on a lower level and shouldn't pose a problem to the grade separations above.
A major flaw though is that there are small roundabouts on the N81 either side of the junction. It's questionable if an N81/M50 junction improvement is useful when traffic would probably just get stuck at these roundabouts a couple of hundred metres later.
Please give your opinion on this road proposal. Rate it out of 10, and whether you think the standard (road width) is appropriate.
