A supply tunnel at the Spa-Francorchamps circuit in Belgium collapsed on Sunday morning, leading to doubts over the serviceability of part of the track.
The tunnel, built in the late 1970s, ran under the sweeping Blanchimont corner, leading from outside the circuit to the interior, where a kart track is located. Its collapse did not injure anyone.
The latest reprofiling of the track, which is due to hold the Belgian Grand Prix later this season, took place in 2007 when the Bus Stop chicane was remodelled. It is not thought that the reprofiling contributed to the tunnel’s collapse, although Blanchimont is just down the road from where the works took place.
The track will have to be examined by structural experts before any racing event can be held, but it is not thought that the tunnel’s collapse will affect the Grand Prix.
