Hi, my name is Christian. I present to you one half of the Sydney Harbour Bridge.
The Sydney Harbour Bridge connects Sydney's north and south coasts across Sydeny Harbour (Port Jackson), Australia. It was completed in eight years, from 1924 to 1932.
In addition to the famous Sydney Opera House, the Sydney Harbour Bridge is Sydeny's/Australia‘s second world-famous landmark. (The bridge was added to the List of Historic Civil Engineering Landmarks in 1988 and was listed as a national monument on the Australian National Heritage List in 2007.)
The pure span of the Sydney Harbour Bridge is 503 meters. At the top of the arch the bridge is 134m high. The headroom for ships is 54m. It is 50 meters wide and consists of around 53,000 tons of steel. This makes the Sydney Harbour Bridge one of the widest, heaviest and longest arch bridges in the world. The 89m high pair of granite-clad pillars is for decoration only. The load from the roadway and the truss arch is transferred to a large foundation.
John Jacob Crew Bradfield and Ralph Freeman are considered to be the bridge's builders. A total of around 1,600 people were employed on the construction of the bridge, of which 16 people died durig construction works.
The bridge has space for eight lanes, two train tracks, a bicycle path and a pedestrian path. That's why the bridge model is 12 studs wide. The scale of the model is about 1:500. It took me about 2 weeks to create the bridge in the computer and another week to build special details in real to see, whether the details can also be implemented technically. The model, one half of the bridge, consists of approx. 2,800 bricks. However, it is of course possible to build two halves and then join them together to represent the entire length of the bridge.
I’m a civil engineer and I particularly like bridges. I love the slim and graceful nature of bridges. I always admire how people can create such structures.
Nowadays in real life, huge buildings often run out of time and out of costs because of a big (too big) complexity and so many different conflicting interests. This makes it all the more satisfying to be owner, builder, planner and construction company in one person if your building project is made of Lego. And voilá – it works.
The Eiffel Tower, which was released as a Lego model in 2022, impresses with its beautiful truss. But there are so many other beautiful truss structures in this world that deserve to be made into Lego models. The Sydney Harbour Bridge in particular, with its beautifully curved steel truss arch and its impressive dimensions, is a modern building that is, without a doubt, a masterpiece of modern engineering and is admired by so many people.
From a technical point of view, the interaction of compressive and tensile forces can be seen best in bridges. From a social point of view a bridge overcomes obstacles and connects people. Apart from that, in my opinion it is high time that another bridge, except London Tower Bridge, is included in the Lego program.
Why not continue with one of the most beautiful bridges in the world?
