Ian McKinnon Drive Cycleway

Ian McKinnon Cycleway will connect the Northwestern cycleway and Dominion Road cycle lanes to the Grafton Gully cycleway, Te Ara I Whiti – Lightpath, and Nelson Street cycleway.


Project status: Design
Project zone: Central


Project overview


The project will create a dedicated cycleway from the end of the Northwestern cycleway through Suffolk Reserve and along Ian McKinnon Drive to Upper Queen Street.

Currently, the Northwestern cycleway finishes near Newton Road and people on bikes need to do a big loop or cross at the traffic signals at Newton Road to access Ian McKinnon Drive. This loop is indirect and time consuming.

To use the existing shared path on Ian McKinnon Drive, people on bikes coming from the Northwestern cycleway need to cross this wide, busy road.

There are often conflicts between pedestrians and people on bikes using the existing shared path on Ian McKinnon Drive. The existing shared path on Ian McKinnon Drive varies in width, has a poor quality surface in some sections, and has some steep sections.

Benefits

  • Save around 2.5 minutes for people on bikes using this connection now.
  • Cyclists and pedestrians won’t need to wait at the lights at Upper Queen Street and Ian McKinnon Drive.
  • A greater length of the path will be separated from vehicle traffic on Ian McKinnon Drive.

The Ian McKinnon Cycleway is part of AT's cycling and walking programme.

Project details


The cycleway has been divided into 2 sections:

Section 1: Suffolk Reserve

The first section of the cycleway goes through Suffolk Reserve from Takau Street, joining the northern edge of Ian McKinnon Drive under the Newton Road Bridge.

This section of the cycleway is approximately 200m long and is proposed to be a 3m wide concrete path that is shared by pedestrians and people on bikes. The route of the path through the reserve is currently indicative until further onsite investigate works are completed.

The current route has been selected to minimise the impact on surrounding properties and vegetation, while avoiding the steepest parts of the hill.

Section 2: Ian McKinnon Drive

This section covers Ian McKinnon Drive, starting near Newton Road Bridge and finishing at Upper Queen Street.

We have short listed 2 options for this section of the cycleway:

Option A: Replace one south-bound traffic lane along upper and lower Ian McKinnon Drive

This option involves constructing a new 3m wide two-way cycleway on the northern side of Ian McKinnon Drive. The cycleway will use 1 of the existing city bound traffic lanes heading up Ian McKinnon Drive towards Upper Queen Street.

To ensure there are still 2 traffic lanes in this direction, 1 of the southbound traffic lanes (heading out of the CBD towards Dominion Road) will be removed for the entire length of the cycleway.

Key features of option A are:

    • A 3m wide two-way cycleway with 0.5m wide raised island providing separation from the traffic lane (similar to Beach Road).
    • Two city bound traffic lanes.
    • One south bound traffic lane. Traffic modelling shows the impacts on traffic flow of losing one southbound traffic lane will be minor.
    • No change to the existing kerb line and shared path on the southern side of Ian McKinnon Drive.

Option B: replace 1 south-bound traffic lane along uppper McKinnon Drive

This option involves constructing a new 3m wide two-way cycleway on the northern side of Ian McKinnon Drive. The lower (southern) half of the cycleway will use the motorway maintenance road.

The upper half will use 1 of the existing city bound traffic lanes, but to ensure there are still 2 traffic lanes in this direction, 1 of the south bound traffic lanes will be removed.

Key features of option B are:

    • Upper Ian McKinnon Drive – a 3m wide two-way cycleway with a 0.5m wide raised island providing separation from the traffic lane (similar to Beach Road).
    • One southbound traffic lane along upper Ian McKinnon Drive. Traffic modelling shows the impacts on traffic flow of losing this land will be minor.
    • Two city bound traffic lanes.
    • Lower Ian McKinnon Drive – a 3m wide two-way cycleway with a 3m wide grass verge providing separation from the traffic lane.
    • All 4 traffic lanes will be retained along lower Ian McKinnon Drive.
    • No change to the existing kerb line and shared path on the southern side of Ian McKinnon Drive.

Advantages and disadvantages of each option

Option Advantages Disadvantages
Option A: Replace 1 south bound traffic lane along upper and lower Ian McKinnon Drive.
  • Creates a dedicated cycleway separated from general traffic.
  • Construction cost are within project budgets (least costs)
  • Removes 1 of the southbound traffic lanes along Ian McKinnon Drive. Traffic modelling shows that the impacts on traffic flow will be minor.
  • The cycleway and road layout will need to be changed if light rail is implemented.
Option B: Replace 1 southbound traffic lane along upper Ian McKinnon Drive.
  • Creates a dedicated cycleway separated from general traffic.
  • Large separation (3m) between cycleway and general traffic on Lower Ian McKinnon Drive.
  • Retains 4 traffic lanes along Lower Ian McKinnon Drive.
  • Construction costs are within project budgets (medium).
  • Removes one south bound traffic lane from Upper Ian McKinnon Drive. Traffic modelling shows the impacts on traffic flow will be minor.

  • The cycleway and road layout will need to be changed if light rail is implemented.

Other options considered

AT commissioned a feasibility report to investigate different possibilities for the Ian McKinnon Cycleway. Options presented in the feasibility report (as well as option A and B) are set out below.

Minor improvements

This option involves minor improvements while retaining the existing cycleway alignment.

This option includes improvements to cycleway route signage and delineation as well as minor improvements to the path surface which is cracked and uneven due to tree root heave. No change will be made to the existing road layout, cycleway gradient or cross-section.

Signal phasing at both the Newton crossing and the Ian McKinnon Drive crossing at Upper Queen Street will also be reviewed to improve travel time for cyclists and pedestrians.

Advantages

  • Can be implemented quickly and cheaply.
  • No construction impacts affecting general traffic on Ian McKinnon Drive.

Disadvantages

  • Does not significantly improve the level of amenity for cyclists or pedestrians 

Eastern widening

The section through Suffolk Street Reserve remains the same as in Section 1.
The cross section for this option includes a 3m wide bidirectional cycleway, replacing the north bound kerbside traffic lane (as in option A)
This option retains two general traffic lanes in each direction by widening the carriageway by 3m to the south, removing the verge and retaining a 2m wide footpath.

Advantages

  • Provides an improved level of service for cyclists travelling in both directions between the North-western Cycleway and the CBD.
  • Provides an improved level of service for cyclists travelling from Dominion Road to the CBD.
  • Retains 4 traffic lanes so that light rail can be implemented in the future while retaining two traffic lanes and without affecting the cycleway.

Disadvantages

  • Lower level of amenity for pedestrians on the southern side of Ian McKinnon Drive with the removal of the verge, trees and reduced footpath width.
  • Cyclists travelling from the CBD to Dominion Road will have to undertake an additional crossing at Piwakawaka Street.
  • High construction cost and complexity. Required the removal of trees, relocation of kerb and channel and potential relocation of underground services.

One-way cycle lanes

The section through Suffolk Street Reserve remains the same as in the Section 1.
This option provides one directional 1.8m wide cycle lanes with 0.3m wide physical separation on both sides of Ian McKinnon Drive. The existing kerblines, verge and footpath are retained and one south bound lane is removed as in Option A.

Advantages

  • Provides an improved level of service for cyclists travelling in both directions from Dominion Road.
  • Provides an improved level of service for cyclists travelling from the North-western Cycleway to the CBD.

Disadvantages

  • Cyclists travelling from CBD to the North-western Cycleway will have to undertake an additional crossing of Ian McKinnon Drive.
  • The road layout will need to be changed again if light rail is implemented in the future.

Retain all traffic lanes

Advantages

  • Creates a dedicated cycleway separated from general traffic.
  • Large separation (3m) between cycleway and general traffic on Lower Ian McKinnon Drive.
  • Retains 4 traffic lanes along the entire length of Ian McKinnon Drive.

Disadvantages

  • Construction costs exceed project budgets due to the requirement of a retaining wall (highest cost).

Future-proofing for light rail

Ian McKinnon Drive has been identified as a potential route for the Light Rail project, but it’s important that we provide the cycleway now as the possible construction of light rail is several years away.

This means we need to provide a safe and efficient route for people on bikes that is also cost-effective; we don’t want to spend too much money on something that will potentially be affected by construction of light rail.

Note that the planning of this section of the Light Rail project will include a cycleway. 


Have your say


From 1 to 29 August 2016. we sought feedback to help us improve the cycleway design and select a preferred cycleway option before we progress to the detailed design stage of the project.

Feedback summary

In total, we received 298 feedback submissions:

  • 66 hardcopy feedback forms.
  • 230 through the online survey.
  • 2 pin-drops on the online map.

We proposed two alternative routes for the Ian McKinnon Drive section, and asked submitters to rank their support for each of these. Both options include a dedicated cycleway along the northern side of Ian McKinnon Drive:

  • Option A replaces one southbound traffic lane along upper and lower Ian McKinnon Drive, to create space for an on-road cycleway from Suffolk Reserve to Upper Queen Street.
  • Option B replaces one southbound traffic lane along upper Ian McKinnon Drive to create space for an on-road cycleway on this section. The lower (southern) half of the cycleway will use the motorway maintenance road.

Submitters like both Ian McKinnon Drive options, with 72% supporting Option A and 13% opposed. Similarly, 73% of respondents supported Option B, with 11% opposed.

We also invited submitters to comment on the proposed Suffolk Reserve section of the cycleway, on each Ian McKinnon Drive option, and on the project in general. Several key themes were identified from these comments:

  • 162 submitters expressed general support for the project/proposal.
  • Several submitters suggested that people on bikes and pedestrians should be separated in Suffolk Reserve (54 submitters), and that pedestrians should be accommodated on the proposed cycle path along the northern side of Ian McKinnon Drive (49).
  • A number of respondents had concerns about how the new cycleway would connect to existing routes in the area. These included Takau Street (16 comments), Dominion and Sandringham Roads (20), Symonds Street via Alex Evans Street (16) and Te Ara I Whiti – Lightpath and Grafton Gully (18).

Decision and changes

As a result of the feedback received on the proposal, AT has:

  • Decided to proceed with the proposed Option B – replace one south-bound traffic lane along upper Ian McKinnon Drive. The lower (southern) half of the cycleway will use the motorway maintenance road.
  • Increased the width of the majority of the proposed path through Suffolk Reserve from 3m to 4m.
  • Increased the width of the proposed cycleway along Ian McKinnon Drive from 3m to 4m and reduced the proposed width of the vehicle traffic lanes on upper Ian McKinnon Drive accordingly.

Next steps

Following analysis of the feedback received, we will develop a detailed design proposal for the new cycle route.

The detailed design will be finished by July 2017. This phase of the project may involve some further engagement with directly affected residents and property owners.

Construction of the route is planned to start in September 2017. Construction is expected to be completed by March 2018.
