Quarantine Road roundabout improvements underway


Work is now underway on the Quarantine Road roundabout in an effort to make drivers, cyclists and pedestrians safer, the upgrade is expected to be completed in July.

NZTA regional performance manager Mark Owen says the joint NZ Transport Agency/Nelson City Council project will future proof the intersection to cater for significant increases in traffic volumes projected over the next 20 years.

The $2.2m roundabout upgrade will be carried out at the same time as road strengthening work is undertaken by Nelson City Council between Nayland Road and State Highway 6.

“By working together on key arterial route upgrades with the council we’re aiming to minimise disruption to the travelling public” says Mark.


The new roundabout layout will include:

  • Extra lanes added at the approaches from Nelson, Richmond and Quarantine Road.
  • Widening the median island in Quarantine Road
  • Extending the pedestrian / cycling crossing point on Quarantine Road.
  • Relocating the footpath on the corner around the Nelson Junction site. A wire rope barrier will be added on this corner.
  • Upgrading street lighting to LED.


Work on site commenced earlier this week, with contractors starting work away from the road to avoid disrupting holiday traffic. Once traffic volumes have reduced in March, the main work will begin and run through to July.

Speed restrictions will be in place for the duration of the work and traffic will, at some times, be restricted to a single lane. Regular updates will be provided to keep road users informed of the work.
