羽田アクセス線、開業３１年度に　東京駅と直通、計画２年遅れ―ＪＲ東

　ＪＲ東日本は４日、東京都心と羽田空港を結ぶ新線「羽田空港アクセス線（仮称）」で計画するルートのうち、東京駅方面の「東山手ルート」について２０３１年度の開業を目指すと発表した。当初計画は２９年度の開業予定だったが、２年遅れとなる。開業により東京駅と羽田空港間は乗り換えが不要となり、約１８分（現在は約３０分）で移動できるようになる。（2023/04/04-20:16）

East Japan Railway Co. , or JR East, said Tuesday that it now aims to open a new train line connecting JR Tokyo Station and the Japanese capital's Haneda Airport in fiscal 2031, two years later than the initially planned fiscal 2029.
   The new line will allow passengers to travel between the station and the airport without changing trains in around 18 minutes, compared with about 30 minutes on existing lines.
   Construction for the new airport line will begin in earnest in June. In the 12.4-kilometer section between the airport and an area near JR Tamachi Station, a tunnel will be built while existing facilities such as elevated tracks will be renovated.
   A new station will be built in an underground area between the airport's Terminal 1 and Terminal 2.
   The project is estimated to cost about 280 billion yen.
