Not long now and these stands will be jammed with Formula One fans. The construction goes on for months - I can't remember when it started but probably in March. Here's a list of what has been installed:

1100 tonnes of stands
900 tonnes of terraces
33 kilometres of security rails
20,000 square metres of wire netting
5000 protection tyres
500 fire extinquishers
32 surveillance cameras
10 cranes
