The FIA's Charlie Whiting will consider possible changes to the bridge section of the Valencia street circuit.

According to the Spanish newspaper Diario AS, tyre supplier Bridgestone is concerned that a small height gap between the two sides of the swivelling swing bridge may cause punctures.

Whiting and his aides inspected the section - as well as the rest of the street layout - before lunch on Thursday, as did most of the twenty formula one racers during their on-foot sighting laps.

Honda's Rubens Barrichello, the most experienced driver in F1 history, raised another concern about the bridge section after he walked the track.

He fears that if cars stop or crash on the bridge, which is about 100 metres long, race control may need to stop the race.

"It's not even a safety car issue," the Brazilian told reporters. "You would have to take the car away and bring trucks onto the bridge."
