Extension Schipholtunnel

Project description

Due to the high volume of air traffic at Schiphol airport, an additional taxi lane was needed to ease the flow of flights going in and out of Schiphol every day. Therefore, Schiphol Group requested Tunnel Engineering Consultants to design a taxiway viaduct to be located just south of the existing Schiphol tunnel, which can be regarded as an extension of the tunnel.
