Major infrastructure works on critical urban corridors are often assumed to require prolonged disruption and community dissatisfaction. The seven month closure of Walmsley Road in Māngere, Auckland, challenged this assumption. The closure was required to enable completion of essential flood resilience works following the 2023 weather events in Auckland. This project demonstrates how working in partnership, a comprehensive Disruption Minimisation Plan combining early and sustained community and stakeholder engagement with rich, real-time transport data, enabled a materially different project outcome. Rather than relying on static modelling and reactive mitigation, a collaborative co-located Working Group was set up and a single source of truth using live traffic, freight, public transport and incident data was used. This approach allowed rapid identification of emerging issues, timely implementation of targeted mitigations and transparent communication with affected communities and stakeholders.
The result was a significant reduction in anticipated congestion impacts, maintained public transport reliability, rapid resolution of issues as they arose and strong community support for a full road closure that enabled faster construction and reduced flood risk. The project demonstrates that with the right planning, partnership working, live data and proactive engagement, major works to provide stronger and safer communities can be delivered more efficiently while retaining public trust and support. This project successfully demonstrates delivery of the overall conference theme of "smart transport and better outcomes" and there are number of lessons learnt from the project which could be applied to future infrastructure projects involving road closures.
