新西兰SH2示范项目：Waikare Gorge 改线分析
政府正在推进位于霍克湾（Hawke’s Bay）与瓦伊罗阿（Wairoa）之间的2号国道（SH2）Waikare Gorge 改线工程。交通部长克里斯·毕晓普（Chris Bishop）表示，目前已正式签约进入详细设计阶段。
毕晓普表示：
“我们都知道这段SH2对当地道路使用者、货运运营商以及每天使用这条走廊的社区有多重要。政府在2025年初已确认资金，现在看到项目持续推进非常令人鼓舞。”
“该SH2峡谷改线项目将分两阶段进行，目前已进入第一阶段——详细设计阶段。新西兰交通局（NZTA）已将该合同授予 HEB Construction。”
“该改线工程将把公路移出峡谷区域，并建设一座跨越峡谷顶部的新桥，从而避免车辆通过这一脆弱路段。初步设计显示，将建设一座260米长的单跨桁架桥，跨越峡谷，高出河面约60米。”
“本周，当地土地所有者和社区可能已经看到施工活动开始，HEB正在进行地质勘测，以支持最终详细设计。同时，NZTA也在推进相关土地收购工作。”
“前期工程预计将在今年晚些时候启动，主体施工将在设计、审批及土地收购完成后开始。整体施工预计最长需要4年完成。施工期间交通影响将尽量降低，因为新路将在现有SH2之外建设，只有在未来连接新旧道路时才会影响现有交通。”
“近年来我们已经看到这一路段的脆弱性，尤其是在Waikare Gorge区域。气旋加布里埃尔（Cyclone Gabrielle）曾严重影响该地区，虽然当时安装了临时桥梁恢复通行，但现在看到永久性替代方案推进令人欣慰。”
“我也要感谢当地国会议员凯蒂·尼蒙（Katie Nimon）对该项目的积极推动与支持。”
编辑备注：
- 项目预计成本为3.5亿至4.25亿纽币
- 先前的桥梁设计为“网络拱桥”，仅用于早期概念示意
- 目前峡谷上仍有一座单车道临时（Acrow）桥，将在新工程完成前继续使用
The Government is continuing to make progress on the State Highway 2 (SH2) Waikare Gorge realignment between Hawke’s Bay and Wairoa, with a contract now awarded for the detailed design phase to get underway, Transport Minister Chris Bishop says.
“We know how critical this section of SH2 is for local road users, freight operators, and the wider communities who use this corridor every day. With funding confirmed by the Government in early 2025, it’s great to see further progress being made on this crucial project,” Mr Bishop says.
“The SH2 Waikare Gorge realignment project is being contracted and delivered in two phases, with the detailed design phase the first part to get underway. NZTA has awarded this contract to HEB Construction.
“The realignment will shift the highway away from the gorge and introduce a new bridge spanning over the top, removing the need to travel through a vulnerable section of SH2. Initial designs have been provided to NZTA, and they show a 260 metre long single-span truss bridge crossing the gorge – 60 metres above the river.
“This week, landowners and the community may have started to see some activity on site as HEB carries out geotechnical investigations to inform the final detailed design of the project. In parallel, NZTA will also be finalising outstanding property acquisition.
“Early works are expected to get underway later this year, with main construction starting once the design, consenting and property acquisition are completed. Construction is expected to take up to four years to complete. Traffic disruption will be kept to a minimum, as it will be constructed away from the existing SH2, except when it comes to connecting the new road to the existing state highway in the future.
“We have seen in recent years how vulnerable this section of SH2 is, especially through Waikare Gorge. Cyclone Gabrielle hit the area hard, and while a temporary bridge was installed to restore access across the river, it is great to see progress being made on a permanent replacement for this critical corridor.”
“I want to thank local MP Katie Nimon for her strong advocacy for this project and her community.”
Notes to editor:
The project is expected to cost between $350 and $425 million.
The previous bridge design over the Waikare Gorge was a ‘network arch bridge’ – this was used solely as an example in NZTA’s initial design.
A new artists impression of the SH2 Waikare Gorge bridge design as at May 2026 is attached below.
A temporary (Acrow) bridge currently crosses through Waikare Gorge. It is a one lane bridge and will remain in place until the realignment project is complete.
