The journey from the Zuidas to Amsterdam Airport Schiphol takes approximately 8 minutes.[4] Future development could include an underground line directly to the airport. Another high-speed link has been proposed by a consortium of companies between Amsterdam Airport Schiphol, Amsterdam Zuid and the city of Almere.
The Zuidas already has good underground connections to other business areas with the Circle Line. With the completion of the North South line, the Zuidas has an even better connection to the city center. The city council is not only investigating expanding the underground network to Amsterdam Airport Schiphol but also upgrading the hybrid metro/light rail line that stops at Amsterdam Zuid.[5]
Between 1998 and 2004, the World Trade Center Amsterdam was renovated[9] and expanded.[10] In 2005, floor space in Zuidas amounted to 3,000,000 square metres (32,000,000 sq ft).[11] Rapid expansion of Zuidas continued after 2005.[12]
The main infrastructural axis (Ring-A10) is scheduled to be tunnelled, transforming the entire area. This would add an estimated €2 billion to the cost of the plan.
