Aerial Perspective View of Mercedes Brooklands Development - the top and right hand sections of the 
test track are parts of the original Campbell Circuit designed by Sir Malcolm Campbell and opened in 1937. The track still crosses the little bridge over the River Wey, originally turning left back up the clubhouse. The track on the right hand (east side) of the river has now been destroyed and forms part of the Sony and Prudential Assurance car park areas. 
The circular green area at the top of the drawing will in fact be a skid pan when it is finished.
