We must also be cognisant of the impact the Luas will have on traffic movements in the city generally. One does not have to be a transport engineer to see that the junction of the M50 and N7 is a mess – even the Minister has accepted this is the case. The Red Cow roundabout is now known as the "Mad Cow" roundabout. The junction was under-engineered from the outset and we are now paying a huge price in appalling traffic congestion. It is about to get even madder because – some may find this unbelievable – two level crossings will be placed across two slip lanes of one of the busiest roundabouts in the country. While I sincerely hope this piece of engineering does not cause massive traffic congestion in the whole west Dublin area, I find it hard to see how this will be avoided. Its impact on traffic movement could be chaotic.
