Northern Arterial – CCC decision welcomed

Christchurch City Council (CCC) today voted on the Christchurch Northern Corridor project. We applaud their decision today as a step in the right direction. I predict that the decision will likely delay the opening of the Christchurch Northern Corridor south of QE2 Drive.

Elected members unanimously passed the recommendations by the joint Linwood-Central-Heathcote and Papanui-Innes community boards to reject the Downstream Effects Management Plan (DEMP) for the Christchurch Northern Corridor. The recommendations were passed in a slightly amended version from what the joint community boards resolved; see below for the details.

The likely delayed opening is due to concerns that the negative impacts from significant increases in traffic volumes have not been addressed for the St Albans community. For example, under the city council’s original proposal, traffic volumes on Cranford Street were expected to more than double from an existing 21,000 veh/day (to 48,000 veh/day within 5 years), effectively splitting the community in half.

I have been helping the St Albans community since an initial meeting on 9 March 2019. We’ve had a few dozen meetings since; it’s been a very time-consuming process. But we have significantly shifted the project over the last 3 months; from the initial “how do we mitigate the negative effects of all this additional traffic” to a conversation about how to minimise the amount of traffic that we get in the first place.

The alternative plan that I developed during the 9/10 March weekend uses two of the four lanes of the Northern Arterial for express bus services. This proposal has been adopted by the St Albans Residents’ Association; we have since been asking for bus priority lanes so that commuters have convenient and reliable travel options rather than car travel being increased.

The agencies delivering the project are, at this point, considering a city-bound high-occupancy vehicle lane and express bus services for four hours per day. We argue that’s not good enough yet, and we will further work with the agencies to advance their thinking.

Mayor Lianne Dalziel summed up the situation as follows:

This is an issue that was inherited from an earlier time, and I don’t think that anyone in their right mind today would actually prioritise these so-called “Roads of National Significance” over the top of the absolute need to face up to the reality of our dependence on fossil fuels that single occupancy vehicle use absolutely encourages. … This is what the climate emergency was all about, is actually facing up to the reality that things do need to change.  There is a frustration that you can hear in my voice. Times up! Times up for our dependency! We actually have to find a better way.

We need healthy streets to live on


The 13 June 2019 city council resolution was passed unanimously:

15. (LCH & PI) Christchurch Northern Corridor Downstream Effects Management Plan
Council Resolved CNCL/2019/00114
