Belgium road map

Belgium road map.

The road network in Belgium is managed by regional authorities, meaning that a road section in Flanders is managed by the Flemish Government, a road section in Brussels by the Brussels government and a road section in Wallonia by the Walloon Government. This explains that road signs in Flanders are written in Dutch, even when referring to a Walloon region, and conversely, which can be confusing for foreigners who do not know the different translations of Flemish or Walloon cities in the other language. The road network in Belgium is made of highways, national (or regional) roads (the secondary network) and communal roads (or streets). Communal roads are managed at the municipal level. There are also a number of orbital roads in Belgium around major cities.

Belgian road numbering evolved during the middle decades of the twentieth century, in a relatively inconsistent way. Road number allocations became less systematic during the surge in road building that took place in the 1960s and 70s. Frequently downgraded and deteriorating older national roads retained two digit numbers while newer major roads were identified with less instantly memorable three digit numbers, if only because the shorter numbers were already taken. 1985 saw a comprehensive renumbering of the "N" (National) roads.
