The Red Cow was a problem before Luas came on the scene. All of the interchanges on the M50 were under-engineered from the start. Instead of cloverleaf junctions, we have roundabouts. The net result is gridlock and the motorway is unable to fulfil the function for which it was built, namely, to carry traffic around Dublin. Every major city in continental Europe has a motorway system around it, taking heavy traffic off its city streets. This is one of the reasons buses and trams work so successfully on other cities. We need a similar motorway system for Dublin and it is clear that the M50, as it currently stands, is not able to fulfil that role.
