SH3 Mangapepeke涵洞更换工程完成

2026年5月26日

交通部长 Chris Bishop 表示，位于新普利茅斯（New Plymouth）以北的国道3号（SH3）两处新涵管已完工，这是政府优先桥梁更换计划的一部分，有助于提升这一关键生命线道路的韧性。

“加强基础设施韧性是本届政府的优先事项。SH3对货运、旅游以及沿线社区都至关重要，我很高兴看到这两处涵管的更换工程已经完成，”Bishop先生表示。

他说：“最近几周我们也看到SH3在道路使用中的重要性，尤其是在Awakino Gorge地区天气事件造成的影响。虽然这些涵管位于峡谷以南，但提前更换以防止未来失效，是对路线的长期保障。”

“水以及如何将其远离道路，是影响道路网络韧性的最大挑战之一。我们必须确保所有新的涵管和桥梁在设计时都考虑未来需求，能够更好地应对水流并有效导流。”

他表示，老旧的Mangapepeke No.1和No.2涵管已被列入政府优先桥梁更换计划，并同步完成施工。这些新涵管分别长21米和30米，其中一处为3×3米结构，另一处直径4米，两者设计寿命均为100年。

该项目于2024年7月在2024–2027年国家陆路交通计划（NLTP）中获批启动。此后，又新增5个优先地点，NZTA正在推进设计、审批与合同工作。

“修复和升级基础路网是本届政府的重点。全国许多桥梁因年久失修而需要限速或限重，因此必须在资金允许时及时更新为更现代、更具韧性的结构。”

他说，国家公路对货运与旅游至关重要，也是各地社区的重要生命线，必须得到良好维护与管理，因此这些更新工程非常重要。

在更内陆的SH43“遗忘世界公路”（Forgotten World Highway）靠近Taumarunui地区，Kururau Stream水渠桥替换工程也接近完成。旧结构为约80年前人工开挖涵管，已因自然侵蚀受损，新桥长20米，改善了道路线路。

“新桥提供了更具韧性的解决方案，确保SH43未来多年安全可靠。施工大部分在现有道路外进行，对道路使用者影响较小，预计6月中旬完工。”

Bishop也感谢当地社区在施工期间的理解与支持，以及施工团队的努力。

Two new culverts have now been completed on State Highway 3 (SH3) north of New Plymouth, as part of the Government’s priority bridge replacement programme, helping to improve the resilience of this critical lifeline, Transport Minister Chris Bishop says.

“Building better resilience into our infrastructure is a priority for the Government. SH3 is a critical lifeline for freight, tourism, and all communities living alongside it, and I’m pleased to see work to replace and upgrade these two culverts completed,” Mr Bishop says.

“We’ve seen in recent weeks how crucial SH3 is to road users, particularly the impacts of weather events through Awakino Gorge. While these culverts are further south of the gorge, replacing them before they fail is important for future proofing the route.

“Water, and keeping it away from our roads, is one of the greatest challenges facing the resilience of our roading network. We need to make sure all new culverts and bridges are designed with the future in mind. They need to better be able to handle water flow and divert it appropriately away from our roads.

“The ageing Mangapepeke No. 1 and Mangapepeke No. 2 culverts were part of the government’s priority bridge replacement programme and work to replace them was delivered at the same time. These new culverts measure 21 and 30 metres in length, while one is 3 by 3 metres and the other is 4 metres in diameter. These new culverts both have a lifespan of 100 years.

“The work to repair or upgrade nine priority bridges and culverts was given the green light in July 2024 as part of the 2024-27 National Land Transport Programme (NLTP). Since then, a further five priority locations have been added, and NZTA is progressing design, consenting, and contracting so work can start.

“Fixing the basics of our roading network is a priority for this Government, and with many bridges across the country requiring speed and weight restrictions due to their age and condition, it is essential priority bridges are replaced when funding is available with more modern and resilient structures.

“Our state highways are critical routes for freight and tourism and serve as important lifelines for communities around New Zealand. We expect our state highway bridges to be well maintained and properly managed, which is why this replacement and maintenance work is so important.

“Further inland, on the State Highway 43 Forgotten World Highway, near Taumarunui, work is almost complete on the Kururau Stream Water Drive bridge replacement. The previous structure is a hand dug culvert, which is about 80 years old, and has suffered natural erosion over time. The new modern 20-metre bridge bypasses the old structure with an improved road alignment.

“The new bridge is a more resilient solution and ensures SH43 will remain safe and reliable for years to come.The majority of the bridge’s construction has been carried out away from the existing road, meaning there’s been minimal impact to road users. Final work on this bridge is expected to be complete mid-June.

“I want to thank local communities for their patience and understanding as these works have been carried out and the crews working on the projects.”
