The flooding in south-east Spain that has killed at least 52 people damaged the circuit where the MotoGP season finale is set to take place, leaving it inaccessible by  vehicle, according to news reports in Valencia.

Circuito Ricardo Tormo’s access roads were badly damaged, although the racing surface itself appears to be unscathed, according to a statement by the Formula E series, which is set to test at the facility next week.

Video on social media showed huge sinkholes in the access road leading to the track.

Formula E representatives at the circuit were trapped and had to spend the night inside the track facility, according to a statement issued by the series.

“Our thoughts go out to those affected by the extreme weather conditions in Spain. Due to damage to the main access road caused by a burst river bank nearby, the circuit is currently inaccessible by vehicle,” the series said in a statement posted on its website.

“Four members of Formula E staff stayed at the circuit last night as a precaution, but are safe and able to transfer to and from the circuit by foot. Track conditions show no signs of damage, and we continue to assess garages and freight. Alternative access routes in and out of the circuit are currently being investigated.”

BBC news reports say that the region experienced a year’s worth of rainfall in eight hours. The Associated Press currently is reporting 52 confirmed deaths, with dozens missing.
