New York has opened the most expensive train station in the world on the site of the World Trade Center, which was destroyed 14 years ago in the Sept 11, 2001 attacks.
Twelve years in the making, there was no official ceremony to mark the opening on Thursday of the World Trade Center Transportation Hub, next to the site of the Twin Towers, which were destroyed in the Al-Qaeda hijackings.
The centre connects the Path commuter rail to New Jersey with New York subway lines, provides indoor pedestrian access to the Trade Center towers and will also house an enormous shopping and restaurant plaza.
The building, designed by Spanish-Swiss architect Santiago Calatrava and called Oculus, is a giant oval made up of steel ribs and glass laid out in elliptical shape, reaching for the sky like wings of a bird.
The space measures 107m long by 35m at its widest point, according to Calatrava's website.
The project has been heavily criticised for its appearance and also for spiralling so drastically off budget and closing seven years behind schedule.
The cost has risen to US$3.85 billion (S$5.31 billion), from an initial budget of US$2 billion, according to a spokesman in Calatrava's office, making it the world's most expensive station.
