“天道是代表直布罗陀HM政府在上岩自然保护区建造的最新景点，是一个更广泛的改善项目的一部分，目的是向当地人和游客提供新的和多样化的方式来享受直布罗陀岩。在更广泛的总体规划项目中，还建造了一座70米长的悬索桥，修复了许多以前的军事炮台和设施，并在新建的步道上引入了解释性和定向标志。

"The Skywalk is the newest attraction built in the Upper Rock Nature Reserve on behalf of HM Government of Gibraltar, as part of a wider project of improvements carried out with the aim of providing locals and visitors alike new and diverse ways to enjoy the Rock of Gibraltar. The wider master-plan project has also seen the construction of a 70-metre long suspended bridge, the restoration of numerous former military batteries and installations and introduction of interpretative and directional signage along newly established walking trails.

该遗址位于岩石的最高点之一，位于少数几个向东和向西提供景观的地点之一，提供了一个独特的有利条件，可以在不同的世界相交的欧洲和非洲、地中海和大西洋上俯瞰全景。它就在道格拉斯路的下面，通向奥哈拉炮台，再往南一点-岩石上的最高点。

The site is situated in one of the highest points of the Rock, in one of the few locations where views are afforded both east and westwards, providing a unique vantage point from which to take in panoramic views over a landscape where different worlds meet: Europe and Africa, the Mediterranean Sea and Atlantic Ocean. It sits immediately below Douglas Path, which leads to O'Hara's Battery a little further to the South - the highest point on the Rock.

天道结构是建立在一个以前存在的具有历史意义的军事平台之上，曾在二战期间作为高射炮基地。该项目的设计愿望是为游客提供新的、无与伦比的全方位景观，包括在下面的岩石悬崖面，同时确保微妙的干预，不减损这一独特环境的自然和历史性质。这条带有玻璃地板和栏杆的悬臂式人行道环绕着这座具有历史意义的石阶平台，钢楼梯提供了通往原来军事平台水平的通道，在那里，旧的八角混凝土炮基地现在是游客休息和眺望远处地平线的一个座位。

The Skywalk structure has been built above a previously existing historic military platform once serving as a base for anti-aircraft Bofors guns during WWII. The design aspiration of this project was to afford the visitor with new and unrivalled views in all directions including over the rocky cliff-face below, while at the same time ensuring a subtle intervention which did not detract from the natural and historic nature of this unique setting. The cantilevered walkway with glazed flooring and balustrade is wrapped around the historic stone platform, with steel stairs providing access to the original military platform level above where the old octogonal concrete gun base now serves as a seat for visitors to rest and gaze out towards the distant horizon.

新增加的构成一个2.5米宽的人行道，悬臂横跨陡峭的地形，全玻璃地板和栏杆最大限度地提供全方位的景观。该构筑物用70m岩石锚定在岩石上，每个锚承担15吨的拉力；确保该结构不仅能承受以上游客施加的负荷，而且还能承受超过150公里/小时的相当大的风速，这是在岩石脊上产生的风速。全景升降机提供了从下面的道路水平进入的另一种途径，它也是整体结构设计的组成部分，将整个悬臂式结构锚定在地势上。

The new addition constitutes a 2.5m wide walkway which cantilevers over the steeply dropping terrain, with fully glazed flooring and balustrades maximising the views afforded in all directions. The structure is anchored to the rock  with 70m of rock anchors, each supporting a tensile load of 15 tonnes; ensuring the structure can withstand not just the imposed load of visitors above but also the considerable wind speeds of over 150 km/h which are generated over the ridge of the rock. The panoramic lift which provides an alternative means of access from the road level below also serves as an integral part of the overall structural design, anchoring the overall cantilevered structure back to the terrain.

由于进入这一地区的车辆仅限于非常狭窄和蜿蜒的道路，整个人行道结构必须在较小的区域内建造，这些部分可以在现场运输和组装-在气候条件迅速变化的地区，鉴于下面陡峭的悬崖面，这是一个相当大的挑战。装配进一步受到可使用的起重机大小的限制，因为这需要根据其所处的旧军事平台进行尺寸调整。主钢结构共18块，总重量超过3万公斤。玻璃模组包括超过750平方米的玻璃面板(大约相当于4个网球场的面积)，重量最大的部件约650公斤。“

Because vehicular access to this area is limited to very narrow and winding roads, the entire walkway structure had to be fabricated in smaller sections which could be transported and assembled together in-situ - a considerable challenge in an area with rapidly changing weather conditions and given the steeply dropping cliff-face below. The assembly was further constrained by the crane size that could be utilised, as this needed to be sized on the basis of the old military platform on which it was positioned. The main steel structure constitutes 18 separate pieces, weighing a combined total of over 30,000kg. The glazing modules comprises over 750m2 of glass panels overall (roughly the equivalent area of 4 tennis courts), with the largest component weighing in approximately 650kg."
