Key Takeaways
- The New Zealand Transport Agency Waka Kotahi (NZTA) will contribute 53% of the estimated total project cost for a roundabout in Hastings, while the Hastings District Council will fund the remaining 47%.
- The roundabout aims to improve safety at a location with a history of serious crashes, and is expected to reduce the risk of harm to locals and communities.
- The project includes full road surface reconstruction, safety improvements, drainage works, and traffic management, and is designed to be effective in an 80km/h area.
- Construction is due to begin in mid-January and continue through to May, with temporary speed restrictions in place to minimize disruptions.
Introduction to the Project
The Hastings District Council has announced plans to construct a roundabout at a high-risk intersection in the area, with the goal of improving safety and reducing the number of serious crashes. According to a council spokesperson, the New Zealand Transport Agency Waka Kotahi (NZTA) will contribute 53% of the estimated total project cost, while the Hastings District Council will fund the remaining 47%. This significant investment underscores the importance of addressing the safety concerns at this location, which has a long history of serious crashes.
Safety Benefits of the Roundabout
Hastings mayor Wendy Schollum emphasized the importance of preventing fatal or serious injury crashes at this intersection, stating that "preventing even one fatal or serious injury crash at this intersection matters." The roundabout is designed to significantly improve safety at this location, which is used by many locals on a daily basis. By reducing the risk of crashes, the project aims to minimize the harm that can have long-lasting effects on families and communities. The council’s director of infrastructure, Darren de Klerk, noted that smaller bolt-on roundabouts were assessed but ruled out as unsuitable for this high-volume, higher-speed intersection used by heavy vehicles.
Design and Construction Details
The project involves more than just the construction of the roundabout itself. According to de Klerk, the project includes full road surface reconstruction on all approaches, heavy-vehicle-specific design features, safety improvements, drainage works, relocation of power and telecommunications services, and traffic management. The design of the roundabout takes into account the 80km/h speed limit in the area, with features such as appropriate entry angles, a large central island, and splitter islands on each approach to reduce speeds and provide safer crossing opportunities for shared path users. This comprehensive approach ensures that the roundabout is not only safe but also functional and efficient.
Construction Timeline and Traffic Management
Construction on the roundabout is due to begin in mid-January and continue through to May. To minimize disruptions to traffic, both lanes of the road are expected to remain open for most of the construction time, with temporary speed restrictions in place. This will help to reduce the impact of the construction on locals and commuters who use the road on a daily basis. The council’s efforts to balance the need for safety improvements with the need to minimize disruptions to traffic are commendable, and demonstrate a commitment to finding practical solutions to complex problems.
Economic Benefits of Improved Safety
The economic benefits of improved safety at this intersection cannot be overstated. According to national estimates, the average social cost of a fatal crash is $4.9 million, a serious injury crash $923,000, and a minor injury crash $104,000. By reducing the number of crashes at this location, the roundabout project has the potential to generate significant economic benefits, not to mention the incalculable value of saving lives and preventing injuries. As the council continues to invest in safety improvements, it is likely that the community will see a range of benefits, from reduced healthcare costs to increased economic productivity.
