新西兰SH39永久性Mangati大桥重建工程正式启动 预计2027年初恢复双向通车
新西兰华人每日资讯网 2026年7月8日讯
新西兰交通部长Chris Bishop今日宣布，New Zealand Transport Agency（NZTA）已将位于Waikato39号国道（SH39）Mangati大桥永久重建工程合同授予工程公司Oxcon，标志着这项重要交通基础设施修复工程正式进入建设阶段。
今年3月，受强降雨和突发洪水影响，连接Ōtorohanga与Pirongia之间的原Mangati大桥严重受损，无法继续使用。为尽快恢复交通，NZTA迅速架设了一座单车道临时Acrow（贝利式）钢桥，保障当地居民和过往车辆通行。
Chris Bishop表示，永久桥梁预计将在本月底前正式开工，并计划于2027年初建成通车，届时SH39将恢复双向通行能力。
新建桥梁将在原桥址重建，但桥面将建得更高、结构更坚固，以提升道路面对洪水及极端天气的抗灾能力。施工期间，车辆将继续使用现有的临时桥梁，因此对SH39交通影响有限。
交通部长指出，SH39是新西兰西部怀卡托地区的重要交通干线，也是连接Taranaki与Auckland的重要运输走廊，对居民出行、物流运输及区域经济具有重要意义，因此政府将恢复双向通车列为优先项目。
据了解，整个项目预计总投资约1250万新西兰元，资金来自NZTA紧急工程预算。其中约800万新西兰元用于新桥建设，其余资金将用于拆除受损旧桥，以及临时Acrow桥的安装、维护和最终拆除等相关工程。
此次永久桥梁建设完成后，将进一步提升SH39的交通安全性、运输效率及道路韧性，为怀卡托地区居民和企业提供更加可靠的交通保障。
Transport Minister Chris Bishop announced today that a construction contract has been awarded by the NZ Transport Agency (NZTA) to Oxcon for the two-lane replacement of the Mangati Bridge on State Highway 39 (SH39) between Ōtorohanga and Pirongia.
“NZTA has worked at pace since a single-lane Acrow (Bailey-style) temporary bridge was installed in March to reconnect the Pirongia community following heavy rain and flash flooding which damaged the original bridge beyond repair,” Mr Bishop says.
“Construction for the permanent replacement is expected to start on site before the end of this month and it will be open to traffic by early 2027,” Mr Bishop says.
“The new bridge will be built higher and stronger, improving the corridor’s resilience to flooding and extreme weather events.
“SH39 is a vital route for traffic travelling through the western Waikato, and an important link between Taranaki and Auckland. That’s why it’s a priority to restore the road to two lanes of traffic by early next year.
“The new Mangati Bridge will be constructed in the same location as the original bridge, meaning there will be minimal impact to SH39 traffic which will continue to use the temporary bridge until the permanent one opens.
“I look forward to work getting underway on a new two-lane bridge that will provide safer, more reliable access for this community,” says Mr Bishop
Notes to editor:
The total project cost is expected to be $12.5 million, funded from NZTA’s emergency works budget. This figure includes the cost of the new bridge ($8 million), removing the damaged bridge and installing, maintaining and then removing the temporary Acrow bridge.
