The incredible 'dragonfly bridge' concept that folds up and sails the river to set up in new locations

• The bridge is the vision of London-based architect Margot Krasojevic who is known for experimental designs
• It was commissioned by the Ordos City government in Inner Mongolia to cross the Wulan Mulun River
• The innovative concept has the ability to fold up for transport as well as to adapt itself to its surroundings
• This would allow the bridge to move up and down the river through onboard sails or by towing the structure

An incredible footbridge concept that resembles a robotic dragonfly could one day be used by pedestrians in Inner Mongolia.

The futuristic concept is the vision of London-based architect Margot Krasojevic, who is known for her experimental and cutting edge designs.

Her latest ambitious creation would have the ability to fold up for transport, as well as to adapt itself to its surroundings.

This would allow the bridge to move up and down the river, which would be achieved either by towing the massive structure or by onboard sails which would allow it to propel itself.

KANGBASHI DISTRICT

The innovative project was commissioned by the Ordos City government who were looking for a new crossing for the Wulan Mulun River, in the Kangbashi district.

The Kangbashi District of Ordos City has previously hit headlines as a ghost city, which remains empty despite having been built around six years ago and being able to accommodate up to one million people.

The urbanisation project is part of a larger government initiative to move 250 million Chinese citizens from rural areas to cities by 2026.The innovative project was commissioned by the Ordos City government who were looking for a new crossing for the Wulan Mulun River, in the Kangbashi district.  

Speaking to MailOnline about the design, Dr Krasojevic said: 'The revolving sail boat was inspired by the FLIP boats which rotate by 90 degrees and float when in position.

'The revolving sail bridge tries to define a new typology for a bridge, which synthesises movement and flexibility like a yacht. 

'The structure is shown at different scales with all the configurations of walkways expanded giving an idea of flexibility and location. 

'I attempted to design a bridge which adapts to the changing urban fabric, a design to hopefully reflect a city’s constantly fluctuating population and programmatic density, why should it be stationary? 

'Why can’t it have another use when it is not a bridge?

'A pop-up restaurant, quayside coffee shop even a cinema. Cities demand adaptable design rather than a static and debilitating architectural presence.' 

The bridge consists of a main floating section that supports three expanding walkways and a carbon fibre triple sail.

The bridge consists of a main floating section that supports three expanding walkways and a carbon fibre triple sail. This folds into multiple sections that stack into each other and supports a hydraulic secondary structure which a pedestrian walkway extends from

Its movement depends on where the sailboat bridge is berthed or sailing to, expanding and contracting into the main body of the primary structure as needed. The bridge can be moored along a quayside, sailed into any location along the river or permanently positioned using Caisson foundations, a watertight structure used as a bridge pier

The bridge can be moored along a quayside, sailed into any location along the river or permanently positioned using Caisson foundations, a watertight structure used as a bridge pier. 

These can be floated and sunk into position, stabilising the bridge. 

Screw-in moorings, along with nine ton anchors, are also used to ensure stability and prevent the structure from drifting away.

The hydraulic walkway is supported by the river bank's landing docks while the main body of the bridge is kept afloat by the sail and its rotator. The walkway’s and the ring frame's weight distribution will prevent it from capsizing

The primary ring frame has eight marine flotation airbags to further stabilise the sail rotation. The sails are made of lightweight aluminium frame, clad in a carbon fibre reinforced polymer

MARGOT KRASOJEVIC'S PREVIOUS CONCEPTS

Dr Krasojevic's ambitious architectural ideas have hit the headlines a number of times over the years.

In 2014, she made waves in the design industry with her vision of a stunning home powered by hydroelectricity. 

The Hydroelectric Tidal House aimed to harness the consistent and powerful movement of waves to generate energy. 

Ms Krasojevic has also designed a futuristic manmade reef with an electric field designed to attract calcium carbonate from the water in a bid to form new reefs quickly.

Her other designs include a futuristic pavilion that acts as an integral part of Paris’ flood control infrastructure.

Located on the banks of the Seine, the structure would divert floodwater into outlying lakes and reservoirs via a series of underground canals 

She has also dreamt up a futuristic trimaran yacht that would operate 100 per cent self-sufficiently with power generated by solar panels on the wingsail and cost an estimated £9 to 10million.

The primary ring frame has eight marine flotation airbags to further stabilise the sail rotation. 

The sails are made of lightweight aluminium frame, clad in a carbon fibre reinforced polymer.

They are suspended from a rotating Mobius ballast chamber which is hydraulically operated by a thruster to rotate and fill with water in order to revolve the sail and relocate the bridge. The rotating Mobius element is made from lightweight aluminium enveloped in stabiliser fins and photovoltaic cells which power the thruster

It consists of five ballast tanks which fill with water and which rotate the sail from horizontal to vertical. The other four tanks are left filled with air so that the sail remains buoyant when used either as a bridge or sailed to a new position

An array of cylindrical crossflow turbines skim the water's surface. Acting as a raft, their buoyancy helps support and stabilise the bridge's primary structure

When the bridge is in use, the sail is lowered and acts as a canopy over a seated area for people to enjoy the views and the platform gardens

The bridge unhinges from the hydraulic triangular section ring frame and rotates into vertical position in order to sail down the river

Solar panels line the walkway providing energy for the three electric motor generators. 

The bridge can be towed, sailed or motored into different locations along the Wulanmulun River.
