Initially built in 1994 this structure was further extended in 2009 when additional lanes were added to the toll station.
A double layered space frame comprised of two initial 65 meter segments.
When the space frame was lengthened in 2009 to accommodate the new road and toll station width, the initial segments were extended to 68 meters each and an additional 35 meter long segment was added to the structure.
Rather than demolishing an existing structure to accommodate an additional 35 meter width requirement and then rebuilding, space frames provided a very convenient solution to the client by extending the existing structure seamlessly. Elements within the pre-existing structure which required additional strength were easily replaced with larger tubes or nodes depending on the case to accommodate for the extra load.
A footpath was added for servicing the toll booth signs and services to the outer perimeter of the space frame.
