Bio: the tight upper section is three lanes wide each way and I believe a similar hairpin was used in the original circuits if you look at the footage from some of the last races around '96 you'll see that there is a very tight hairpin and interestingly enough it was one of the best spots for overtaking. As for them going each way Te Papa has some big glass windows looking out over the road around where there restaurant is, imagine having lunch watching cars zoom either way outside
