looks like when they get to abbey they turn right and head infield to a new section and back out to where the bridge used to be missing out the bridge dip :(

mind you could be a fast track though
 
the pictures do look weird but hopefully it will make it world class facilities

as for the layout they are heading from abbey to brooklands to meet up with the national circuit i beleive, the idea to create more overtaking oppotunities i think
