Hi Philippa, http://cyclingchristchurch.co.nz/cycle-infrastructure/first-look-southern-motorway-cycleway-pt-1/ explains a little bit about this, but Part 2 of this post (now that the last bit is being sealed) will explain how the gap will be filled in the next couple of years.

I would love to know why they built a lovely bike track alongside the southern motorway and then it stops halfway and then you can pick it back up just off lincoln road. It is quite ludicrous as most cyclists want to follow where the traffic is going i.e. down to Brougham Street. I would use that route if it was complete but I instead go along sparks road to get to Brougham as it is quicker and more direct from Halswel.. Thank you for listening and taking time to come to this organisations AGM
