Yeah, something is going to have to give with traffic in that area. With yesterday's heavy rain, residents of Woodstown were reporting that it took them 45 minutes just to get out of their estate. I can't imagine what kind of pain people further up the road had to deal with.
I had made a suggestion for the local area plan that there needs to be a footbridge/cycle bridge across the M50 from Knocklyon Park to Orlagh Grove. This would massively cut down on congestion - most people from this area drive their kids to school because the walk is 20 minutes on a good day. If there was a direct walking/cycling route, many people would go with that rather than sit in traffic for half an hour every day.
Never heard anything back on the suggestion though :/
