Devon Street West Cycle Separator Trial

In early 2026, we're conducting a trial on a section of SH45/Devon Street West to test alternative cycle separators and a range of other safety measures.

As part of the trial, the current concrete cycleway separators will be replaced with a mix of rubber humps and cycle separators. 

These alternatives are lower, narrower, and will be spaced further apart than the existing concrete sections.

Why we’re doing this

In December 2025, the Mayor and Councillors approved a trial to help determine the best long‑term design for this busy transport corridor. As part of the decision, they asked staff to:

  • replace the current concrete separators with options that most vehicles can safely drive over, and
  • monitor how both the existing and new layouts perform, then report back in September 2026 to help inform future decisions.

This trial lets us test new options in real-life conditions.

We want to understand whether the design changes maintain, improve or reduce safety for pedestrians, cyclists and motorists. We’ll also assess whether the changes help address concerns raised by motorists and local residents.

The concrete cycle separators were originally installed as part of the previous Government’s Transport Choices programme. Those works were completed in 2025.

We’ll report the results of the trial to the Mayor and Councillors in September 2026. At that time, Council will decide whether to keep the current layout, adjust the designs, or remove the separators along the full corridor.

Temporary changes being made

  • Rubber cycle separators and humps will replace the existing concrete ones in the trial area.
  • A shared footpath on the northern side of the road, for use by novice cyclists. 
  • A painted on‑road, unprotected cycle lane, for experienced and confident riders.
  • A wider flush median and a full-sized right-hand turning bay at Cutfield Road intersection. providing more space and making it safer for right-turning traffic, including emergency vehicles.
  • Nine on-street carparks introduced on the northern side of Devon Street West.
  • A bus stop is being slightly relocated but will sit in westbound cycle lane.

Additionally, the right hand turn into Morley Street is being reinstated.
