Germanys Federal Administrative Court in Leipzig has given the green light to construction of the controversial Berlin-Brandenburg International airport (BBI) on the site of the old East Berlin airport at Schneberg, ending a legal battle lasting over ten years. However, the 4,000 local residents who opposed the airport on environmental grounds have claimed partial victory after the same court ruled that the airport authorities must take measures to limit noise levels and reduce the overall environmental impact on the surrounding area. There is also a ban on night flights between midnight and 05.00. Scheduled to open by 2011, the new airport will eventually replace Berlins Tegel and Tempelhof airports.
