I'm in two minds about it. The bit already at 110 is the most suited part, it's straight and flat. The start is pretty decent too. There's just this massive, very steep part that seems the most risky. A pileup there seems like a really bad situation. Maybe we have the first 30km or so at 110, the wiggler up and down bits at 100, then back to 110 on the flat?
Alternatively, put it all at 110 but put in one of those new average speed cameras, just on the riskier bit, so people have to go at 110 rather than adding another 10 or 15.
I’m looking forward to this actually, I drive that road a lot, and this will represent a significant time saving on a round trip.
The part still at 100kph is by my maps measurement 37km long. Taking a little over 22 mins to drive at 100kph. Increasing this to 110kph makes this a little over 20 mins, a saving of 2mins each way or 4 mins from a return trip. I don't know that it would be that significant, but you'd still get most of that gain if you did the first 30km at 110.
