The acquisition of field data has increased considerably in Beauvais (Oise) since the creation of a municipal service of archeology in 1992. This is an opportunity to take stock of the new data available on the city in the Early Roman period, and more specifically on the roads that structured it. The streets all appear to have been built according to a stereotyped model : a carriageway, side ditches and a covered pavement. More generally, the aim is to provide an overview of the known sites and to attempt to identify some of the features that can be discerned in the urban layout. The organisation of the city is not yet discernible due to gaps over large areas, but the cardo maximus does appear to be the only real guiding axis around which the monumental adornment in particular developed.
