Weymouth (Clendon) roundabout safety improvements
We’re delivering staged safety improvements at the Weymouth (Clendon) roundabout to make crossings safer and improve travel through this busy intersection.

Walking, driving and busOverview
We are improving safety and access at the roundabout where Weymouth Road, Roscommon Road, Mahia Road and Palmers Road meet in Clendon.
This is a busy intersection used by people driving, using buses and walking to shops, schools and local
facilities.
The project is being delivered in 2 phases.
Phase 1 is complete, delivering new zebra crossings and safety upgrades. After phase 1, we monitored how the roundabout is working in practice.
The Phase 2 improvements respond directly to what the monitoring showed, focusing on making crossings more visible, encouraging safer speeds and improving driver behaviour.
When will phase 2 happen?
We plan to make these changes in winter 2026.
We will inform the community before works start, including confirmed dates, staging and any temporary traffic management.
Latest updates
Following monitoring after phase 1, we are progressing phase 2 safety
improvements.
Construction timing is to be confirmed.
We are engaging with the community about these planned changes and will update them before work starts.
Timeline
Phase 1 - Delivered safety upgrades
Phase 1 delivered zebra crossings on all approaches and supporting safety upgrades around the roundabout.
Phase 2 – Additional safety improvements
Phase 2 responds to monitoring results after Phase 1. It focuses on improving driver awareness at crossings, discouraging unsafe overtaking, and improving visibility.
Why this is needed (Phase 2)
After phase 1 was completed in 2025, we watched how the roundabout is being used every day. Our monitoring shows:
- Some drivers approach the roundabout and the zebra crossings at higher speeds and, at times, do not stop for people crossing.
- We recorded 19 near misses on Roscommon Road, mainly from drivers not giving way or overtaking using the shoulder.
- We recorded five near misses on the other approaches, where drivers went through the crossing before people had fully crossed.
- There was a serious incident involving a vehicle and a pedestrian on Palmers Road.
- The Phase 2 improvements respond directly to these issues. They focus on making crossings more visible, encouraging safer speeds, and improving driver behaviour at the roundabout.
The improvements we’re making (Phase 2)
- Installing pedestrian‑activated electronic warning signs on Roscommon Road and Palmers Road approaches to the zebra crossings - these signs will display “SLOW DOWN” with flashing orange lights when someone is waiting or crossing.
- Installing traffic side islands near the crossings to help prevent shoulder overtaking and shorten the crossing distance.
- Updating road markings in selected locations, including diagonal flush markings and lane narrowing, to help slow vehicles as they approach the roundabout.
- Trimming vegetation and carrying out tree maintenance at the Roscommon Road and Palmers Road corner to improve visibility for drivers exiting the roundabout.

Project background
In 2021, Auckland Transport sought feedback on proposed improvements at the Weymouth Road, Roscommon Road, Mahia Road and Palmers Road roundabout (reference NOP2021‑019).
The roundabout is on a busy bus route and close to schools, shops and
community facilities, and congestion had become a problem.
Following feedback, we confirmed in December 2021 that the project would proceed.
The design was later refined to keep traffic moving on these key roads while providing dedicated locations for people to cross.
Delivering upgrades in phases allows us to make improvements, then check how changes perform in real conditions and target further improvements where needed.
