The site for the garden exhibition Floriade 2012 Venlo is accessed by a new road called Greenportlane. Arc2 architecten designed a family style for the engineering works for this main traffic road, which include viaducts for motor vehicles and for cyclists, an ecoduct and a railway viaduct. Their shared features are wooden balustrades, embankment hard surfacing with natural materials and an integration of the road into the landscape. Arc2 developed the viaducts on a basis of the Cradle-to-Cradle.
