Silverstone is set to spend £5m improving spectator viewing and making its circuit more ‘bike friendly’ before staging the British MotoGP motorcycling race in 2010.
A new section of track will be built from the approach at Abbey corner into an area dubbed ‘Arrowhead’ at the inside of Becketts.
The Northamptonshire venue recently signed a five-year deal to host MotoGP.
After unveiling the provisional plans, managing director Phillips added: “The new layout will be more suitable for two-wheeled racing. Silverstone Circuits Limited are making a significant investment, but it is absolutely worth it. Early feedback from both riders and drivers has been very positive.’
Phillips confirmed the current grand prix circuit would remain unaffected for the 2009 British F1 Grand Prix, which will take place on 21st June.
Silverstone will stage its final British F1 Grand Prix this year before the flagship race moves to Donington Park in 2010 as part of a new 10-year deal.
