This article traces the implicit spatial project of Belgian engineers during the interwar period. By analyzing infrastructure planning and its inscribed spatial ideas as well as examining the hybrid modernity advocated by engineers and politicians, this article contributes to both urban and transport history.
Unlike colleagues in countries such as Germany, Italy and the United States, Belgian engineers were not convinced that highways offered a salutary new order to a nation traumatized by the First World War. On the contrary, the Ponts et Chaussées asserted that this new limited access road would tear apart the densely populated areas and the diverse regional identities in Belgium. In their opinion, only an integration of existing and new infrastructure could harmonize the historically fragmented and urbanized territory. Tirelessly, engineers produced infrastructure plans, strategically interweaving different transport systems, which had to result in an overall transformation of the territory to facilitate modern production and export logics.
