这项预算达6,330万美元的Tank Street天桥工程,将为布里斯班市中心提供一个新的自行车及人行天桥通路,使得市中心区与南布里斯班彼此联系起来,并通过另外一条行人与自行车桥――友好大桥将市中心与南岸公园连接了起来。

Tank Street天桥属于由布里斯班市议会于2006年提出的之中心总体规划与昆士兰政府的2008-2006年昆士兰东南地区技术设施规划中的一部分。其设计与修建始于2007年10月1日,预计将于2009年9月完工,届时正好赶上昆士兰州150年纪念庆典。该天桥从Tank Street的北码头一端一直绵延到南布里斯班的Kurilpa Point,靠近新的昆士兰现代美术馆大楼。

Tank Street通过不锈钢栏杆的装饰,就像是用紧绷的钢丝支撑而悬浮在空中的精美雕塑品,同时刚好处于南岸文化区与商业中心区法院的枢纽点上。

该天桥是一个多栏杆的缆桥结构,是按照非固定尺寸的原则而设计的整体结构,其建筑与工程机制在稳定张力与承压构件之间达成了一种协同作用。

Tank Street Bridge is getting a lot of attention as the first large scale tensegrity bridge. The bridge is currently under construction in Brisbane’s inner city. Brisbane is one of today’s fastest growing urban centers in Australia and the bridge is part of the City Centre Master Plan 2006 anticipating an increasing demand for pedestrian areas. It will link the city center to South Brisbane: from Tank Street to Kurilpa Park traversing Brisbane’s navigable river. The construction of the Tank Street Bridge is expected to be completed by September 2009 so that it can be part of Queensland’s 150th year anniversary celebrations.

Tensegrity structures belong to a special category of cable structures. They are defined as systems composed of compression components (struts) inside of a continuum of tension components (cables) in a stable self-stressed state (equilibrium). They are lightweight structures offering higher resistance than other systems of the same weight. Another advantage is their modularity; stable modules can be joined together creating larger tensegrity systems.

From an engineering point of view, the construction of the Tank Street Bridge is a civil engineering achievement. Tensegrity structures are highly complex systems with non-linear behavior. Therefore, the analysis of these structures demands complex computational methods. Additionally, previous tensegrity constructions such as the Rostock tower (Germany) revealed a necessity for high precision. It is also important to mention that there are no widely accepted guidelines for the construction of this kind of structures.

The resulting tensegrity bridge is a network of cables held apart by numerous struts recalling the ropes and spars of sailing ships and boats. Seen from the rivers, struts seem to float over the bridge. They remind sculptures made by the American artist Kenneth Snelson (see “Easy Landing”). Additionally, due to its tensegrity system the bridge offers high transparency with great views over the river to pedestrians. During the night, the bridge will be full of colors. LED lights are chosen to highlight the masts with pastel colors creating a levitating illusion for pedestrians. Different colors will be applied based on the chosen theme creating a contemporary sensation.

Benjamin says: 

About time a nice bridge crossing the Brisbane River!

All others are old and out-dated. This should liven up the river, epecially at night by the looks of things.. nice.

zga says:

it’s a bridge made to be looked at from far off distances and post cards.

MsUnreliable says:

The renders are very striking, but the bridge itself so far looks so much larger and a lot less elegant…hopefully it all comes together nicely and proves me wrong.

And just for reference, Baulderstone Hornibrook Queensland are actually the builders/project managers.

Des says:

Not cool.

Simon says:

ZZZZZZZ. There were better options than this! Pick up stick style architecture is not elegant.

Made to take postcard shots from, not to be included in.

nrw says:

I love engineers too

adam says:

This engineering marvel should be named “Crow’s nest Bridge”.

Awful (at least now, under construction), obscures the views and creates an untidy, busy look in the already busy city!

Alexx says:

I think that it looks great, Brisbane needs more architecturally significant buildings.

Jeanette Fitzgerald says:

I think it is ugly and will always have an unfinished’ look.

Susan says:

Does any one know how people using the bridge get on to the pedestrian/bike path by the river if they then want to continue walking to Toowong?

Rick H says:

Looks fantastic, will do a lot for the CBD.

Steve Crow says:

The unpleasant ‘cage-like’ structure that the bridge now incorporates over the Riverside Expressway was not necessary. The bridge approaches now resemble a high-security prison walkway. Was the cage structure incorporated to remove the temptation for punters to throw items onto the Riverside Expressway? If this is the case – why not cage the Victoria Bridge too!!

The cage has made an otherwise ‘lightweight’ and ‘transparent’, almost ‘floating’ form of construction look bulky and distasteful. What a shame – so much potential!!!

Bobbie Blackson says:

Love it!

Evokes images of tall ships back in the 1800s when they probably sailed up the Brisbane River to offload their cargo in South Brisbane.

A nod to the white settlers, and naming it Kurilpa acknowledges West End – a double gesture!
