If the 19th century was defined by the railway, the 20th century was defined by the highway. In the aftermath of World War II, and particularly during the "Golden Sixties," Belgium embarked on an ambitious program of highway construction. This was the era of the "Nevelstad" (Fog City) or the "Vlaamse Ruit" (Flemish Diamond).
Based on Maarten Van Acker’s seminal research, From Flux to Frame
This is infrastructure as urban acupuncture. The frame (the tunnel and ring road) lifts the highway out of the city and plugs it into a network of bicycle superhighways ( fietssnelwegen ). Instead of a river of flux, Antwerp is designing a framed interface between the port (economic engine) and the city (human habitat). If the 19th century was defined by the

explores the profound, often invisible relationship between large-scale infrastructure and the urbanization of Belgium. It bridges the gap between engineering-led infrastructure design and the architectural and social focus of urban planning. Core Thesis: Infrastructure as the "Armature" Based on Maarten Van Acker’s seminal research, From
Van Acker uses three distinct Belgian landscapes to illustrate how different modes of transport shaped unique urban environments:

Designing infrastructure in Belgium today means navigating the tension between its historical sprawl and a sustainable future. It is about moving from a logic of "separation" (zoning) to a logic of "integration."
The mid-twentieth century brought the most dramatic shift from frame to flux, and then a desperate attempt to reframe. The rise of the automobile and the truck dissolved the railway’s rigid geometry. Belgium, with its flat topography, cheap land, and a political culture that prized individual property rights over collective planning, became the laboratory of lintbebouwing —ribbon development. As the state invested massively in a dense network of national roads (the chaussées ), any landowner could build a house along a road, with a driveway directly onto the asphalt. This was infrastructure as enabler of unregulated flux: no master plan, no greenbelts, just an endless, low-density, semi-urban strip connecting every village to every city.
The "flux" here is constant. Belgium sits at the crossroads of Europe, acting as a transit hub for the continent. The "frame" consists of a dense network of canals, railways, and highways that are among the most concentrated in the world. Designing the Flux: Infrastructure as Urban Catalyst
