F1's governing body on Wednesday revealed that changes to the Valencia street circuit have been made ahead of this weekend's second European grand prix in the Spanish port city.
The FIA said the pit exit has been "reworked to bring it to the same level as the track" while the wall separating the two has been removed.
Walls at the apexes of turns 3, 9, 10 and 14 have been moved back, the wall at the exit of turn 5 moved back by three metres, and openings at the apexes of turns 7 and 11 closed and relocated.
Additionally, artificial grass has been installed behind the kerbs on the exit of turns 10 and 14, and the inner pit lane sealed with a high-grip resin.
