RO&AD：该项目是一条由位于荷兰西南部的一系列堡垒和城市淹没区组成的水中防线，始建于17世纪，但从19世纪开始便已年久失修。当水线重新恢复后，需要建一座横跨要塞之一的护城河通道桥，即Fort de Roovere。

RO&AD：The West Brabant Water Line is a defence-line consisting of a series of fortresses and cities with inundation areas in the south-west of the Netherlands. It dates from the 17th century but fell into disrepair in the 19th century. When the water line was finally restored, an access bridge across the the moat of one of the fortresses, Fort de Roovere, was needed.

这座堡垒的几条自行车和徒步旅行路线上，现在有了新的娱乐功能。当然，在防御工事的护城河上建造桥梁是非常不合适的，尤其是在敌人预计会出现的堡垒一侧。因此我们在此设计了一座隐形桥，其结构完全由木材制成，并辅以三元乙丙橡胶箔防水。这座桥就像堡垒和护城河中的一条壕沟，形状与周围景观轮廓融为一体。你从远处是看不到这座桥的，因为它与地面和水面几乎齐平。当你靠近时，会看到一条狭窄的壕沟向你敞开，引导你像水上摩西一样走到堡垒门口。

This fort now has a new, recreational function and lies on several routes for cycling and hiking. It is, of course, highly improper to build bridges across the moats of defence works, especially on the side of the fortress the enemy was expected to appear on. That’s why we designed an invisible bridge. Its construction is entirely made of wood, waterproofed with EPDM foil. The bridge lies like a trench in the fortress and the moat, shaped to blend in with the outlines of the landscape. The bridge can’t be seen from a distance because the ground and the water come all the way up to its edge. When you get closer, the fortress opens up to you through a narrow trench. You can then walk up to its gates like Moses on the water.
