A tunnel running underneath Spa-Francorchamps collapsed yesterday during a Subaru club track day. No one was injured, but major repairs are necessary ahead of the Belgian Grand Prix in August.

The Blanchimont Entry Tunnel was built in 1978 and passes under the track just before the Paul Frere Corner. It's thought that heavy rains that have beset Europe this winter eroded soil surrounding the tunnel. While the only effect the collapse had on the track itself is a few cracks in the asphalt, there is a hole in the runoff area that will require significant work to repair. While repairs should be completed in time for the Belgian Grand Prix on August 27-29, it's currently unknown what effect the incident will have on other races and events scheduled earlier in the year.
