They need a new airport for Dublin?? Are you mad???
The space around the current site is fine. Its only 6miles from the city center. The only tolls I can think of are for the M25 Toll Bridge, THe M1 way up past Drogheda and when the Dublin Port Tunnel opens. I live in Malahide, my house will be very much effected by the new runway yet very few people in my area are kicking up a fuss. After all, the airport was there long before most of us were.
All they really need to do with dublin airport is blow up the terminal and start all over with a nice swanky design.
