What's your least favourite road in Ireland?

We all have our favourite roads in Ireland such as the beautiful Ring of Kerry or more local to the capital the roads around Sallygap.

But a question popped into my head yesterday on the Dreary N7 that seems to go on forever towards the painful M50 about what people's least favourite roads are.

I believe mine is that stretch of the N7 followed closely by the N4 with their 3 lane roads with painfully low speeds.
