Ninety years ago today (19/3/1932) the Sydney Harbour Bridge was officially opened.

Celebrations were organised to celebrate this milestone, which included light shows, a concert at Campbells Cove and vintage ferries and trains running during the day.

Historic double decker buses took passengers over the bridge from North Sydney to Wynyard and return for a number of hours.

Bridge climbers received a discount of $90. Strangely there were a lot of climbers on the bridge today!

The Sydney Harbour Bridge is one of those imposing structures that you never get sick of looking at when commuting across it.

It is too large and imposing to ever be ignored.

Happy birthday, Sydney Harbour Bridge.

What name should we give this bridge?

Why do they all have to sit upstairs?

And so they climbed, no not because of the discount, but because it’s there.

The Sydney Opera House is located on a prominent point on Sydney Harbour and is a stone’s throw (maybe two) from the Sydney Harbour Bridge.

In 1957 Danish architect, Jorn Utzon, was chosen as the opera house architect from a field of over 200 contestants.

His design sketches were bold and inspiring. It was clear that the proposed building was going to be exceptional.

As with many ambitious plans reality kicked in and numerous modifications of the design were necessary.

This design process was pain staking and it was not until 1963 that the design was finalized.

The greatest challenge concerned the shape of the opera house’s most distinctive feature, large curved vaulted shells.

The shape had to have both structural integrity and the ability to be economically built.

Many shapes were tried ranging from parabolas to circular ribs to ellipsoids.

Ultimately the shape of the opera house’s shells was based on the dissection of a top of a sphere into segments.

One of the many interesting features of the opera house is that the shell walls curve and blend into the roof, joining at a central point.

Jorn Utzon did not want a flat roof and his desire for the opera house to be seen from all sides was satisfied by constructing the shells on an elevated platform (podium).

Due to the massive size of the shells the design had to allow for in situ construction, resulting in the shells being built piece by piece from precast concrete.

The final design chosen for the opera house is in the author’s opinion a significant enhancement of the original drawings, providing for a more upright and striking building, whilst still retaining the look of the original sketches.

Whilst taking the photos for this blog Sydney Nimble came across the Sydney Opera Company’s principal soprano, Julie Lea Goodwin, who will be performing in the upcoming production of La Boheme at the Sydney Opera House.

Julie’s hair, make-up and art deco dress/ gown/ jewellery were exquisite. Nice to meet an opera singer at the opera house!

A popular stop on our custom and eastern suburbs tours is the El Alamein Fountain in Kings Cross.

You may wonder why a fountain at Kings Cross brings on a discussion of World War II. The simple answer is that the El Alamein fountain commemorates two battles fought in World War II near the Egyptian town of El Alamein. More than 1200 Australian infantrymen lost their lives in the El Alamein battles which stopped the Axis forces (German and Italian armies) from taking over Northern Africa. It was a major turning point in the war. Winston Churchill described the siginificance of the El Alamein battles in the following way:

Before Alamein we never had a victory. After Alamein we never had a defeat.

The El Alamein Fountain was designed by Robert Woodward, who worked as an armourer in WW II.

The design of the fountain was inspired by the shape of a dandelion and the frame is comprised of 211 radially dispersed stalks. The stalks shoot out water which creates a bubbly or saucer like film. Wind conditions and direct sunlight will change the look of what you see. Water from the fountain overflows into several layered pools. It is a masterful modernist fountain and highly eye catching should you be walking or driving by. A wonderful mist is created when the fountain is firing. The construction of the El Alamein Fountain was completed in 1961.

Happy 60th birthday El Alamein Fountain!

Perception is often everything in determining how we feel about things. The Sydney Harbour Bridge (SHB) is a structure that can be perceived in many ways. What do you see when you look at the SHB?

From one perspective the SHB is a large steel bridge that allows for the efficient transport of commuters. It provides a crucial transport corridor connecting the north shore of Sydney to the city and several expressways.

Alternatively the SHB can be evaluated from an engineering perspective.

The construction of the SHB began in 1924 and finished in 1932. It was built during a period when computer assisted design and manufacture did not exist. The bridge was built from both ends so that the arch was complete when the two halves of the bridge met in the middle.

Would the two halves align when it was time for them to be joined and how would a steel bridge of this scale deal with expansion and contraction in varying weather conditions. Would the bridge be strong enough to take the large daily load of passenger vehicles and trains.

From an identity viewpoint the SHB is one of Australia’s most well known and popular symbols. It was a brilliant achievement for a young nation and the 100th year anniversary of the commencement of construction is only four years away.

That achievement came at a price. Sixteen workers lost their lives during construction and it took over 50 years to pay off the cost of building the bridge (1988).

Aesthetics as opposed to any functionality was behind the decision to build two massive granite covered pylons at each end of the SHB arch. The four pylons are 89 metres in height and the light grey colour of the granite complements the bluey grey colour of the arch.

The pylons project strength and provide symmetry when the bridge is observed from the distance.

The SHB offers ongoing activities, although a lot of people would not see it in this way.

You can simply drive across it and enjoy the view, walk or cycle across it, climb it, visit the Sydney Harbour Pylon or see it sparkle on News Year Eve when it is used for spectacular fireworks displays.

One final perspective on the bridge is captured in the words of John Bradfield (chief engineer of SHB) who described it as ‘the blue arch of Heaven’.
