Leo Varadkar (Dublin West, Fine Gael) | Oireachtas source

I thank Deputy McGrath. There is roughly €500 million a year in the national roads budget. About half goes to maintaining and strengthening existing roads and about half goes to new projects. It is never the case that we can fully fund every project that we want in any one year. There has been an allocation made to the N24. We have decided that if other road projects run behind schedule or behind budget during the course of the year, we might be able to reallocate money from those projects to other projects such as the N24 but it is too soon to make that call.
