Project introduction

The Rolleston flyover will lift and connect Rolleston’s township and industry hubs over SH1. The flyover for cyclists, pedestrians, buses and local traffic will give people safer ways to cross the highway and make travel more efficient.

Community engagement

As part of the community engagement process we receive community feedback and submissions and speak with many business and property owners, organisations and stakeholders  throughout key stages of the design process, to understand all the varying transport needs and requirements. We make changes and refinements to our proposed plans accordingly.

Feedback was open from 20 July and closed 17 August 2021.

However, you can see what others had to say on our online interactive map.

A summary of feedback and responses will be provided to the public and there will be another consultation opportunity before the end of 2021. Make sure you subscribe to updates using the sign up form below.

About the project

Waka Kotahi NZ Transport Agency is working closely with Selwyn District Council and KiwiRail to plan the NZ Upgrade funded package for Rolleston, which includes investment in highway intersections and rail improvements.

NZUP is investing $6.8 billion to save lives, get our cities moving and boost productivity in the country’s growth areas.

Intersection changes will mean safer and more efficient freight routes and rail corridor, while making it safer and easier for people to drop in and visit Rolleston and exit onto a freer flowing highway.

The long-lasting package of road and rail improvements provides a streamlined extension off the southern motorway while elevating and strengthening Rolleston's community connections. Planning also factors in complementary road and rail projects in the district.

Construction is expected to start in 2024.

Key features

  • Multi-modal flyover over SH1.
  • Intersection safety improvements along SH1 through Rolleston including Dunns Crossing/Walkers Road.
  • Rail improvements.

Speed review area

The current posted speed limits under review are from just north of the SH1/Hoskyns Road intersection through to Dunsandel. The total length of corridor being reviewed is 17.8km. We are at a very early stage of considering speed along this corridor. We want to hear your thoughts on the current speed limits and if they feel right for these areas.

Why it’s important to get involved

Mayor of Selwyn District Council Sam Broughton and James Caygill, Waka Kotahi Director Regional Relationships, talk about the plans for Rolleston.
