Zuidasdok is a project of Rijkswaterstaat, ProRail and the municipality of Amsterdam. It will improve the accessibility of the Amsterdam Zuidas district and the northern part of the Randstad, both by public transport and by road. This will partly be achieved by expanding Amsterdam Zuid Station. The station will become a compact and high-quality public transport terminal where all forms of transport meet. Also the area around the station will be redesigned.
The A10 South will be widened from four to six lanes in between the intersections of the Nieuwe Meer and Amstel. Local traffic and passing traffic flows will be separated. The intersections of the new and Amstel will also be adjusted.
The extension and modernization of the station and the widening of the highway are made possible by building two tunnels for the A10 South. This allows for a reduction in noise and an improved air quality in the central area of the Zuidas district. This means the area can be further developed into a neighborhood with mixed residential and commercial functions.
Zuidasdok is realized by consortium ZuidPlus, a joint venture of Fluor, Heijmans and HOCHTIEF.
