Dominion Road and Denbigh Avenue, Mt Roskill - Roundabout approach improvements Dominion Road and Denbigh Avenue, Mt Roskill - Roundabout approach improvements

Proposal status: closed 7 March 2019

Reference number: RTV-192

We're proposing changes in your area

We are proposing changes to the pedestrian crossing at the southbound approach of the Dominion Road and Denbigh Avenue roundabout in Mount Roskill.

The proposal involves reducing this approach to a single lane, and creating a side-island to shorten the crossing distance for pedestrians.

Why the changes are needed

These changes are needed to improve safety, specifically for people crossing the road. The current layout can block visibility for pedestrians. It is also a double-lane crossing, which is difficult to cross for some.

We also aim to improve the safety on the southern and eastern approach, by proposing to allow heavy vehicles to occupy both lanes on those two legs. This should reduce the risk of a collision taking place.

Proposal outcome

This project will proceed without changes to the next stage of detailed planning. Thank you to everyone who submitted feedback. A summary of this feedback and answers to community questions and concerns is below.

Feedback received

  • This proposal received welcoming responses from community members and stakeholders who supported pedestrian safety improvements.
  • A number of respondents suggested the current configuration of this intersection as a roundabout is insufficient, and traffic lights would be better suited. Dominion Road is currently being considered as a candidate arterial road for an improved public transport link between the city centre and the airport. A large overhaul of the intersection may be considered as part of this future project. We have noted your feedback for future consideration.
  • Concern regarding the traffic islands creating a pinch-point for people on bikes. The reduction of the number of southbound lanes from two to one is expected to significantly improve safety of pedestrians as well as people on bikes. The current lane width is not adequate for a cyclist and car to drive next to one another. Under this new proposal, adequate lane width is created, allowing for sufficient room for a car and cyclist to pass each other.
  • Suggestion to add a crossing on the southern side of Dominion Road after the roundabout, to service students using this intersection. The southern side of the roundabout is very close to the multi-lane motorway interchange. A pedestrian crossing this close to the interchange across multiple lanes is not considered safe.
  • Request for barriers between the road and the footpath to help protect students from ‘swerving cars’. A barrier is not recommended at this location because visibility is good and the barrier itself could become a hazard for road users.
  • It was also suggested that moving the existing zebra crossing closer to the intersection may improve safety. Moving the zebra closer to the roundabout would actually decrease safety, because drivers would not have adequate room to observe a pedestrian and stop when exiting the roundabout.
  • Several people suggested that the best way to improve the safety on this stretch of road is to reduce the speed limit to 30km/h. This section of Dominion Road is an arterial route leading to the highway. Therefore, reducing the speed limit is currently not being considered. The roundabout on this section of road helps calm the traffic, keeping the speed down. The proposed reduction in the number of southbound traffic lanes to one is expected to help calm speeds even more, further improving safety.

Next steps

This work will happen before October 2019, but we will let you know if there are further changes or delays.

Our contractors will send notices to affected residents 48-hours prior to construction starting.
