Belgium covers an area of 30,528 square km. There are 118,414 km of roads, among which there are 1,747 km of motorways. Belgium is divided into two parts which use different languages. That's why road signs in Belgium are either in Dutch or French. The capital city is Brussel.
Following the completion of the Germany city rework in update 1.53, SCS revealed that the Benelux region (Belgium, the Netherlands, and Luxembourg) would be the subject of the next major map rework, dubbed "Project Benelux".

Trivia
Belgium, after Luxembourg, is the second smallest country featured in ETS2. After the Going East! DLC was released, it is also the country with second smallest number of cities featured in-game.
Before the release of Euro Truck Simulator 2, two dots above Brussel can be seen floating above the map, which indicates that Ghent was going to be featured. Due to scale constraints, the city was not available in-game.[2]
It should be noted that despite having a national numerotation system, and having dedicated icons present in the game files, signage in Belgium defaults to using the Euroroute numbering scheme to refer to motorways. In addition, the one road which is signed using national road numbers is the Brussels Ring Road, which doesn't have a map icon in the game files.
