The scale and design of the metro project are also critical. Press reports suggest that what is envisaged is a short link from Dublin Airport to the city centre, not a line across the city. I do not think such a proposal would be right for Dublin as it would not offer a real solution to our traffic problems. There should be no half-measures. If we are to build a metro line, let us build a full line, not half a line. This means running a line straight from the airport to a destination on the south side of the city. Otherwise we would be unique in Europe in having a metro system which terminated in the city centre. It would be madness to have a metro line terminating underground at St. Stephen's Green. We would then have to return in four or five years and start the whole planning process all over again in order to complete the southern line. Surely it makes sense to save time and money by building the whole line as a single project. Piecemeal planning has made a mess of our road system. Let us not repeat the mistake with a Dublin metro system.
