To be fair, it’s been on my own to-do list for a while to update the current suburban guide page as it’s missing most of the recent new cycleway routes. BTW, there is a feedback comment on that page too; I also did a Flashback Friday about it in 2022 and that also has a comment. But I haven’t exactly publicised it widely otherwise.
As for the cost of the cycleways, they are a pittance for the calculated benefits derived; the various motorways around Chch for example cost 4 times as much (and for far less benefit/cost ratio). And if we’re worried about the cost-of-living, I would think that trying to afford paying for a $600 million stadium that will hold fewer people than cycle each day in Chch would be the bigger worry…

If that’s the case, why aren’t all those who are advocating for Christchurch to become a rabbit warren of cycleways (all of which cost a lot of money which is possibly not great during the current cost of living crisis), not coming out of the woodwork and flooding your blog with a plethora of information as to where to cycle?

Legal roads with proper sized intersections and the markings/signs that remain are legal sized.
Almost zero traffic, and what is there is really slow
Excellent visibility through corners – no houses or fences left, no cars parked, and only the odd bush or tree.

Downsides are the poor road surfaces, with potholes and shingle.
