Gladesville Bridge

Gladesville Bridge is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gladesville Bridge rather than just read about it. In short: Gladesville Bridge is a heritage-listed concrete arch road bridge that carries Victoria Road over the Parramatta River, linking the Sydney suburbs of Drummoyne and Huntleys Point, in the local government areas of Canada Bay and Hunter's Hill respectively, in New South Wales, Australia. Despite its name, the bridge is not in Gladesville.

Key takeaways

  • Gladesville Bridge belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Gladesville Bridge to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Gladesville Bridge from memory before moving on to harder problems.

Reference excerpt

Gladesville Bridge is a heritage-listed concrete arch road bridge that carries Victoria Road over the Parramatta River, linking the Sydney suburbs of Drummoyne and Huntleys Point, in the local government areas of Canada Bay and Hunter's Hill respectively, in New South Wales, Australia. Despite its name, the bridge is not in Gladesville. The Gladesville Bridge is a few kilometres upstream of the famous Sydney Harbour Bridge. When it was completed in 1964, Gladesville Bridge was the longest single span concrete arch ever constructed. Gladesville Bridge is the largest of a complex of three bridges, including Fig Tree Bridge and Tarban Creek Bridge, designed to carry traffic as part of the North Western Expressway. The bridge was the first phase of this freeway project that was to connect traffic from the Newcastle via Wahroonga/Lane Cove, then through Glebe/Annandale to connect into the city. Due to community action the freeway project was abandoned by the Wran Government in 1977, leaving the Gladesville Bridge connecting the existing arterial roads. The Gladesville Bridge was designed by Anthony Gee, G. Maunsell & Partners and Eugène Freyssinet and built from 1959 to 1964 by Reed & Mallik (Engineers, England) and Stuart Bros (Builders, Sydney). The property is owned by Transport for NSW. The bridge was added to the New South Wales State Heritage Register on 1 October 2014.

History Europeans first settled in the Gladesville/Drummoyne area of Sydney soon after landfall at Sydney Cove. In the 1790s, Crown grants of 12-hectare (30-acre) lots were made available in the vicinity of Gladesville to encourage agricultural pursuits in the area. The future suburb of Gladesville remained isolated and rural until the 1850s when the earlier land grants were subdivided into large urban building blocks for the development of 'gentlemen's residences' for the wealthier colonists of NSW.

1881 bridge

To provide better access to Sydney, a wharf was soon erected on the Parramatta River at Gladesville and a two-lane steel lattice truss girder bridge with swing span was built across the river between Drummoyne and Huntleys Point. Remnants of the sandstone abutments of the original bridge still exist on the river banks to the south-west of the present bridge. This bridge carried a tramline and road traffic but did not accommodate pedestrians. This bridge, called the Gladesville Bridge, and also known as the Parramatta River Bridge, was opened on 1 February 1881. The old Gladesville Bridge was constructed as part of a series of bridges built during the 1880s, which also saw the construction of the Fig Tree Bridge and the Iron Cove Bridge. It was the only crossing of the Parramatta River east of Parramatta at the time of construction, with punts and ferries (steamers) providing the main methods of crossing the river. The closest crossing to the bridge was the Bedlam Punt, which operated from 1829 through to 1881 between Punt Road in the present-day Gladesville and the Great North Road in present-day Abbotsford. This bridge was also constructed per agitation by the community on providing a tram service from Ryde to the city. The 1881 Gladesville Bridge was about 300 metres (984 ft) to the west of the modern bridge. This original bridge only carried one lane of traffic in each direction as well as a tramway. It featured a swing span on the southern end of the bridge that could be opened to permit sailing ships and steamers with high funnels to pass. 'Sixty miler' colliers from Newcastle would require the bridge to be opened to gain access to the Australian Gas Light Company (AGL) gasworks site at Mortlake, (now redeveloped as Breakfast Point). The bridge stood on iron cylinders with a sandstone pier at each end of the bridge. The sandstone piers are all that remain today of the original bridge, with the northern pier adjacent to the Huntleys Point ferry wharf, and the southern in Howley Park in Drummoyne.

Worked examples

Example 1 — a first encounter with Gladesville Bridge

Start with the simplest possible case. Write down what Gladesville Bridge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gladesville Bridge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gladesville Bridge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gladesville Bridge

In research
Gladesville Bridge appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Gladesville Bridge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Gladesville Bridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 establishments in Australia, Bridges completed in 1964, Bridges in Sydney, so understanding it makes those chapters shorter.
In everyday life
Look for Gladesville Bridge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
