Yeah, I know - another long break!

So, has anyone else noticed the new speed signs by the roundabout at the Mill Rd/Parkhurst Rd/SH16 roundabout. Whose clever idea were they?

Driving from Helensville to Parakai you are in a 70km/h zone on Mill Rd. Right before the roundabout, that changes to 100km/h - great place to speed up, right? But then, the minute you get through the roundabout, it's now an 80km/h zone on Parkhurst. So, 70km/h along the straight, 100 round the roundabout, then 80 along the next straight!

Going from Parakai to Helensville is the opposite - 80km/h along Parkhurst, with a 100km sign right on the roundabout, then drop back to 70km/h entering Mill Rd.

The situation was of course different until very recently - Parkhurst Rd used to be a 100km/h zone, so the signage made sense. But with the drop to 80km/h, it seems no-one thought to rethink the signage.

Now, I'm not a complete idiot (I hope) - I realise that the 100km/h applies to SH16. So why not put the 100km/h sign at the start of SH16 instead of before the roundabout on either side? Obviously, no-one's going to go through the roundabout at 100 (I've tried: it doesn't work - just kidding) - but it seems unneccessarily confusing signage.

I guess the reason is probably some silly jurisdiction thing - the roundabout is probably the responsibility of Transit NZ (ie considered part of SH16) whereas Mill & Parkhurst Roads are probably looked after by the Council. I'm just guessing here, but that seems to be par for the course in matters like these.

Maybe a little common sense in future?
