Calatrava hub design will be tweaked

The Port Authority said plans for the World Trade Center transportation hub designed by Santiago Calatrava will need to be re-engineered because the project is now $1.2 billion over budget. The authority said it will work with Calatrava to retain the architect’s fundamental vision for the hub. The project was originally expected to cost $2.2 billion, but recent estimates show it costing between $2.7 and $3.4 billion. more [NYT]
