road network in 2000, there have been multiple accidents in the Eau Rouge/Raidillon combination. In the day and age where safety is paramount to many racing organizations and governing bodies like the Fédération Internationale de l'Automobile, these crashes, of which some noteworthy ones are listed below, opened up public debate whether the Eau Rouge/Raidillon combination was deemed unsafe. Criticism centred around the nature of the tyre barrier and run-off area of Raidillon, which tended to bounce out-of-control cars back onto the track rather than collect them. In October 2020 the circuit announced that gravel traps would be placed at La Source, Raidillon, Blanchimont, Les Combes and Stavelot. The runoff areas of some corners including Raidillon would be expanded. It was part of an €80 million upgrade to the circuit that would make it able to hold motorcycle races. The upgrade will also include a grandstand at the top of the Eau Rouge/Raidillon hill. The upgrades were completed in March 2022, ready for the FIM EWC race, due to be held in June. The circuit is also shortened, as Jacky Ickx corner is bypassed in favour of a shorter section with more runoff for motorcycles. Fatal crash of Formula 2 driver Anthoine Hubert in 2019 During the Formula 2 feature race in late August, a serious incident between Anthoine Hubert and Juan Manuel Correa occurred shortly after Raidillon on the Kemmel Straight. As the second lap began, Trident driver Giuliano Alesi lost control of his car as he climbed the Raidillon curve due to a puncture he had received earlier, causing his car to spin and hit the left wall of the circuit, tearing off his rear wing and spreading debris onto the track. As another Trident driver, Ralph Boschung reached the crest of Raidillon, he slowed down and moved towards the run-off area to avoid Alesi's damaged car and the field of debris. Hubert, who was following Boschung closely and had no view of what had happened to Alesi, moved right to avoid Boschung's slowing car, clipping Boschung's right rear wheel with his front wing. Hubert's car crashed into the tyre barrier on the right side of the track at an acute angle and was deflected sideways into the path of Charouz driver Juan Manuel Correa, who struck it on the left side in the driver seat area. The incident resulted in the death of Hubert and serious injury to
