View Full Version : Bridge? I don't know, but it's cool!

This is made from Accoya (http://www.accoya.com/technology/) (tm) -- wood that's been acetylated (http://en.wikipedia.org/wiki/Wood_preservation#Wood_acetylation) to preserve it. The wood is reacted with acetic anhydride, converting the free hydroxyls within the wood to acetyl groups, making the wood more dimensionally stable and much less digestable. It's a process that's been around since the 1920s.

The architects of this bridge(?!) are RO+AD (http://www.ro-ad.org/).



A series of moats and fortresses were built over the West Brabant Water Line region of the Netherlands during the 17th century in order to provide protection from invasion by France and Spain. Fort de Roovere was surrounded with a shallow moat that was too deep to march across, and too shallow for boats. In turn the earthen fort had remained protected –until now.

From afar, the Moses Bridge is invisible to the eye. The flow of the moat appears continuous, as the water level remains at the same level, reflecting the surrounding foliage. As visitors approach the fort, the bridge appears as a break in the water with its sloping walls containing it.

First lying flush with the earth, the bridge then descends deeper into the ground. Lined with wood sheet piling for walls, the deck and stairs sit between. The bridge and its components have been made from sustainable hardwood that is Cradle to Cradle Gold certified. The Accoya wood is also treated with a nontoxic coating, protecting it from fungal decay and increasing its durability — an ideal material for a sunken bridge. Like a dam, the walls of the bridge hold the waters of the moat back, and like Moses, the bridge parts the waters so that pedestrians may pass.

The Moses Bridge gives visitors a unique opportunity to pass through parted waters, to eventually meet a historic fortress of defense.

Ingenious, and very well executed. Thanks!

and very discrete, as befits an historical artefact.

I wonder what happens if they get three or four days of rain.

An interesting twist on the vanishing edge.


Pity they tiled the pool with too deep a blue.

I wonder if it has bilge pumps.

That's a unique 'bridge', but would you really call it that?

Wiki says: A bridge is a structure (http://forum.woodenboat.com/wiki/Architectural_structure) built to span (http://forum.woodenboat.com/wiki/Span_(architecture)) physical obstacles such as a body of water (http://forum.woodenboat.com/wiki/Body_of_water), valley (http://forum.woodenboat.com/wiki/Valley), or road (http://forum.woodenboat.com/wiki/Road), for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed, the material used to make it and the funds available to build it.

So this doesn't span, it intersects. A breakwater walkway?

The contrast accentuates the vanishing edge.
The point of infinity pools is you're not supposed to realize there's an edge: in this case you're supposed to feel at one with the ocean.

What's up with those clouds?

Been seeded with blue pills apparently

I would like to see the structure under the walkway :)

I'm reminded of Richard Wilson's artwork (http://www.guardian.co.uk/artanddesign/gallery/2010/jan/12/art-richard-wilson-saatchi-gallery). (Which I quite like. Apparently the smell of gallons of used engine oil was "heady")

Very cool, as long as the water level doesn't change much. I wonder if there's some way to control the level we don't see in the pictures -a stream flowing in and a dam at the outlet, or something similar.

I'm reminded of Richard Wilson's artwork. That seems like something better appreciated in pictures. I've had too much to do with used oil to relish the thought of smelling it. And whoever has to take it apart and clean it up will want to murder him.
