架构师提供的文本描述。耗资3200万新西兰元的下Hatea过境点于2013年7月27日由Wangarei下议院议员菲尔·赫特利、部落长老和当地政要正式开幕，并举行了传统的波韦里式(毛利人欢迎仪式)和庆祝船的漂流仪式。

Text description provided by the architects. The spectacular NZ$32m Lower Hatea Crossing was officially opened on 27 July 2013 by Whangarei MP Phil Heatley, tribal elders and local dignitaries and featured a traditional powhiri (Maori welcoming ceremony) and celebratory floatilla of boats.

由英国专业桥梁设计咨询公司奈特建筑师(Knight Architect)在2011年竞标后设计的这条2.65亿潮水河口通道是高速公路网络中的一个关键组成部分，旨在减少市中心的拥堵，并改善通往万格瑞(Wangarei)的头头和机场的通道。开放的桥梁为河流使用者提供了永久的最低高度空间，并有一个25米宽的起重段，允许7.5m以上的船只通过大桥。

Designed by specialist UK bridge design consultancy Knight Architects following a competitive tender in 2011, the 265m tidal river estuary crossing is a key component in the highway network, designed to reduce congestion in the city centre and improve access to Whangarei Heads and the airport. The opening bridge provides a permanent minimum headroom for river users and a 25m wide lifting section to allow vessels taller than 7.5m to transit the bridge.

开口机构是基于传统的滚动基底桥式，结构钢甲板支架的形状，提供了一个独特的海拔，这既体现了它的有效滚动作用，也体现了它的文化背景-弯曲‘J’形是对鱼钩主题的解释，在毛利文化中广泛使用。这种形式日夜皆可辨认，为进入城镇流域地区提供了一个积极的入口，也提供了一种强烈体现万格里当地特色和文化的结构。

The opening mechanism is based on a traditional rolling bascule bridge type, with the structural steel deck supports shaped to provide a distinctive elevation which speaks both of its efficient rolling action and also its cultural context - the curved ‘J’ shape is an interpretation of the fish hook motif that is widely used in Maori culture. The form is designed to be recognisable by day and night, to provide a positive gateway to the town basin area and a structure that speaks strongly of the local character and culture of Whangarei.

在设计开发的早期，发现了几个相互依赖的方面，它们影响外观、工程、可施工性和成本，这就要求项目团队共同创新。在三维CAD中设计了滚动式基础和相关液压系统，采用复杂的参数化求解器，可以对常规方法中不可能的多变量进行更大的控制和同时处理。与此相比，不仅解决方案达成得更快，而且在更好的容忍范围内，有利于桥梁的成本和外观。

Early in the development of the design, several interdependent aspects were identified that affected appearance, engineering, constructability and cost, and this required the project team to innovate together. The rolling bascule and associated hydraulics were designed in 3D CAD and the use of complex parametric solvers allowed for greater control and simultaneous manipulation of multiple variables not possible in conventional methods. Compared to which, not only were solutions reached far faster, but they were within finer tolerances that benefitted the cost of the bridge and also its appearance.

由于可以测试和理解设计中的变化的速度，随着成本模型变得更加清晰，设计能够作出反应，在不损害总体视觉质量的情况下，通过设计整合变化。

Owing to the speed at which variations within the design could be tested and understood, as the cost model became clearer the design was able to respond, integrating changes through the design without harming the overall quality of vision.
