Council settles on solution for CNC traffic south of Berwick Street

Commentary: the plan to manage traffic downstream of the Christchurch Northern Corridor (CNC) included nine options to manage the motorway’s additional traffic south of Berwick Street through to Bealey Avenue. The Christchurch City Council requested staff to proceed with scoping the three highest-ranking options as part of the first stage of downstream works. One of those options has now been picked and is included in the current consultation on transport projects in the Cranford Street area.

I’ve been following the progress of the Christchurch Northern Corridor for a number of years, and have been covering the Downstream Effects Management Plan in some detail (see links below). It has been my view that the decision around traffic ‘south of Berwick’ was one of the most significant, but also one that hasn’t been clearly communicated.

Consultation on transport projects in the Cranford St area – August 2019

Consultation is open until 19 August on a package of transport projects in the Cranford St area, downstream of the Christchurch Northern Corridor. Here’s an overview of the Council’s consultation document.

Recap: Council’s DEMP decision – why not investigate delaying the CNC?

Item 15 on the agenda for the Council’s 13 June meeting was the Christchurch Northern Corridor Downstream Effects Management Plan (DEMP). As the name suggests, this is the plan to manage the traffic impacts downstream of the Christchurch Northern Corridor (CNC) – the motorway (currently under construction) that will run between Cranford Street and the Waimakariri River.

I attended the community protest ahead of the Council meeting, caught part of the discussion on the DEMP via the livestream, and the rest through the Council’s incredibly handy video archive. At the time I was left wondering: what happened to the recommendation that the Council investigates delaying the opening of the CNC south of QEII Drive?

Boards reject Northern Corridor traffic management plan? Not really?

Recap: “Boards reject northern corridor traffic management plan” ran the headline on the Council’s article summarising the outcome of Friday’s joint Community Board meeting. What happened at the meeting, and what happens next? What does it mean for those intending to use the Christchurch Northern Corridor, and for those living downstream of it?

I was in the public gallery of the Council chambers when the Community Boards met on Friday. I also captured some images of the ‘Turn On The Heat’ community protest held ahead of the meeting. Continue reading “Boards reject Northern Corridor traffic management plan? Not really?”

Residents turn up and turn on the heat

Background: Members of the public partially blocked access to the Christchurch City Council Chambers on Friday, with an ‘interactive installation’ illustrating congestion concerns.

A security guard kept an eye on proceedings, but Council staff and elected members didn’t appear upset by the community action. “It’s been a few years since we had a good protest inside the building” observed one Councillor. Continue reading “Residents turn up and turn on the heat”

Calculating the cost of the Christchurch Northern Corridor

Analysis: The construction of the Christchurch Northern Corridor is nearing completion. It was described as a $240 million project at the time that the construction contract was awarded in 2016. Now that it’s nearly done, is the spending on track? Where is the money going, and who’s paying the bills?

I recently wrote about the benefits that the Christchurch Northern Corridor is expected to deliver. The cost to construct this project is also of public interest. Having reviewed the NZ Transport Agency’s 2011 Final Scheme Assessment Report, and made follow-up inquiries with both NZTA and the Christchurch City Council, I’ll discuss the project’s costs as best I can.

Adding up the benefits of the Christchurch Northern Corridor

Analysis: It’s fair to say that the Christchurch Northern Corridor (CNC) is a contentious project. There are significant costs involved (both financial – more on that in a future article – and in terms of community impact, especially on those living downstream). Given these costs, surely there must be significant benefits on the other side of the ledger?

In a previous career in the technology sector, I’ve been involved in big-ticket product development decisions. These might have been an order of magnitude smaller than a Road of National Significance, but they still required a comprehensive business case.
