The 'new' John Foord Bridge was built between1887 and 1895, and replaced an 1862 timber bridge constructed by a company involving John Foord. A plaque, placed on the bridge by the The Institution of Engineers, Australia names it as a "NATIONAL ENGINEERING LANDMARK". Black and white photograph of two bridges.

Nimons Bridge was built in 1890, as part of the then Ballarat-Linton railway. The bridge is 17 spans with tall timber piers of four driven piles each, with triple sets of diagonal cross-bracing and walers and a single row of longitudinal horizontal bracing between piers. The spans are of a uniform twenty feet (6.1 metres), originally supported by four 21-inch x 9-inch (535 mm x 230 mm) Kauri timber beams per span, following the standard V.R. design of the period. When the superstructure was rebuilt after the 1953 fire, the timber beams were replaced with two 24-inch (610mm) deep rolled-steel-joists on each span. These are marked 'Lancashire Steel Co., Scotland' and are believed to have been second-hand. The deck of transverse-timber planks is 103.6 metres in length. Overall the bridge has an impressive appearance with its exceptionally tall triple-cross-braced piers creating a 'three-tiered' effect, with the deck 19.2 metres above the Woady Yaloak River. The Ballarat-Skipton line closed in 1985. Nimons Bridge has been recently restored, as part of the Ballarat-Skipton Rail Trail. How is it significant? Nimons Bridge is significant for technical, historic and aesthetic reasons at a State level. Why is it significant? Nimons Bridge is technically significant as Victoria's fourth-tallest timber trestle bridge when built, and as the third-tallest surviving example. It is also the second-largest composite bridge combining traditional timber piers with RSJ spans and a timber deck and falls within a select group of fewer than ten timber railway bridges with horizontal longitudinal bracing between the piers and three sets of double cross-bracing on its tallest piers, creating a visually striking 'three tiered' effect that enhances its viaduct form. Nimons Bridge is historically significant as having served initially the mining community at Linton, then the Western District agricultural area and in later years a kaolin quarry at Pittong. Nimons Bridge is historically significant as a representative of the 'light' branch line methodology that stimulated the explosion of railway construction in Victoria during the 1880s, and provides an interesting contrast with the more solid and vastly more expensive railway viaducts built in similar terrain on Victorian main lines, at Moorabool and Taradale, in the late 1850s. Approached by a deep cutting and high embankment at either end, the bridge represents a very cost-effective late 19th century engineering solution to the characteristic physiography of western Victoria with flat basalt plains intersected by deep wide valleys occasionally subject to severe flooding. Nimons Bridge is aesthetically significant for its visually impressive viaduct form, crossing a deep and steep-sided valley that is part of a rich cultural landscape. Within close proximity of the bridge are mullock dumps, tailings, shaft sites and other relics of the deep-lead alluvial mining era. The bridge is the most visually spectacular timber-trestle rail bridge in Western Victoria and is among the most spectacular timber-trestle rail bridges surviving anywhere in Victoria. It is part of the Ballarat-Skipton Rail Trail.

The 1st Royal Australian Naval Bridging Train (1st RANBT) was formed in Melbourne on 28 February 1915 and was intended to be a horse drawn engineering unit attached to the Royal Naval Division (RND), then serving as infantry on the Western Front. The term ‘train’, in its title, was a direct reference to the horse drawn wagons that would, in theory, form and move ‘in train’ to carry the unit’s heavy lumber, building materials and engineering equipment to the front. The unit was manned by members of the Royal Australian Naval Reserve for whom there were no available billets in seagoing RAN ships. Many of the sailors serving in the 1st RANBT were rated ‘drivers’, and again, this refers to wagon drivers as opposed to motor vehicle drivers. Other seamen were rated as ‘artificers’ or ‘sappers’, the latter being a military term traditionally used to describe army engineers. Appointed in command of the 1st RANBT was Lieutenant Commander Leighton Seymour Bracegirdle, RAN. Bracegirdle was ideally suited to command the unit, having seen active service with the NSW Naval Brigade during the Boxer Rebellion in China as well as serving as a military officer in the South African Irregular Horse during the Boer War in 1901. He had also recently returned from German New Guinea where he had served as a staff officer in the joint Australian Naval and Military Expeditionary Force (ANMEF) responsible for the capture of the German colonies in the Pacific in September 1914. Three hundred naval reservists, including 50 men who had recently served in New Guinea, were selected for the 1st RANBT and they began their training in horsemanship, engineering and pontoon bridging at the Domain in Melbourne. By late May 1915 a decision was made to send the unit to Britain to complete its training and then to join the RND on the Western Front. The plan, however, never eventuated. The complaints about the non-combatant work being done by the men had been raised in Federal Parliament and following consultation with the senior Australian officer in the Middle East, Lieutenant General Sir Harry Chauvel, a recommendation was made that the unit be disbanded and its men used as reinforcements for the AIF. Consequently, Lieutenant Commander Bracegirdle was advised that his unit was to be dispersed; its men transferring to the AIF or being returned to Australia for discharge. On 27 March 1917 the 1st RANBT was officially disbanded.Oxidised brass anchor shaped collar badge.ww1, world war 1, first world war, ranbt, ran bridging train, royal australian navy bridging train, collar badge

At the beginning of the 1890s, the Kew businessman and Town Councillor, Henry Kellett, commissioned J.F.C. Farquhar to photograph scenes of Kew. These scenes included panoramas as well as pastoral scenes. The resulting set of twelve photographs was assembled in an album, Kew Where We Live, from which customers could select images for purchase.The preamble to the album describes that the photographs used the ‘argentic bromide’ process, now more commonly known as the gelatine silver process. This form of dry plate photography allowed for the negatives to be kept for weeks before processing, hence its value in landscape photography. The resulting images were considered to be finely grained and everlasting. Evidence of the success of Henry Kellett’s venture can be seen today, in that some of the photographs are held in national collections.It is believed that the Kew Historical Society’s copy of the Kellett album is unique and that the photographs in the book were the first copies taken from the original plates. It is the first and most important series of images produced about Kew. The individual images have proved essential in identifying buildings and places of heritage value in the district.Completed in November 1890, the railway viaduct (now the Chandler Highway Bridge) linked Kew and Fairfield. The viaduct is significant as the most substantial extant engineering remnant of the Outer Circle Railway Line. Opened in March 1891, the viaduct crossed the Yarra River in a single span, atop three supporting brick pillars. Following the closure of the railway line in 1927, and the construction of the Chandler Highway in 1930, the bridge was used for vehicular traffic. In 1891 when this panoramic photograph was taken, the grounds of what was then the Kew Lunatic Asylum extended down to the River and eastward beyond the viaduct. The landscape surrounding the Asylum was planted with traditional exotic trees such as Oaks, Pines and Cedars, and landmark trees from northern Australia such as the Hoop Pine. Remnant indigenous trees such as the River Red Gum, Yellow Box and Lightwood were scattered around the site, including beside the Yarra River.Railway Bridge Over the Yarrakew illustrated, kew where we live, photographic books, henry kellett, railway viaduct - - kew (vic)

The Melbourne and Metropolitan Board of Works (MMBW) plans were produced from the 1890s to the 1950s. They were crucial to the design and development of Melbourne's sewerage and drainage system. The plans, at a scale of 40 feet to 1 inch (1:480), provide a detailed historical record of Melbourne streetscapes and environmental features. Each plan covers one or two street blocks (roughly six streets), showing details of buildings, including garden layouts and ownership boundaries, and features such as laneways, drains, bridges, parks, municipal boundaries and other prominent landmarks as they existed at the time each plan was produced. (Source: State Library of Victoria)This plan forms part of a large group of MMBW plans and maps that was donated to the Society by the Mr Poulter, City Engineer of the City of Kew in 1989. Within this collection, thirty-five hand-coloured plans, backed with linen, are of statewide significance as they include annotations that provide details of construction materials used in buildings in the first decade of the 20th century as well as additional information about land ownership and usage. The copies in the Public Record Office Victoria and the State Library of Victoria are monochrome versions which do not denote building materials so that the maps in this collection are invaluable and unique tools for researchers and heritage consultants. A number of the plans are not held in the collection of the State Library of Victoria so they have the additional attribute of rarity.Original survey plan, issued by the MMBW to a contractor with responsibility for constructing sewers in the area identified on the plan within the Borough of Kew. The plan was at some stage hand-coloured, possibly by the contractor, but more likely by officers working in the Engineering Department of the Borough and later Town, then City of Kew. The hand-coloured sections of buildings on the plan were used to denote masonry or brick constructions (pink), weatherboard constructions (yellow), and public buildings (grey). The absence of buildings and or property in Kew facing the Yarra is the most notable feature of this plan. Walmer Street and its bridge stretched, then and now, from Studley Park Road to Victoria Street, Richmond. On the Richmond side of the Yarra, there was evidence in 1904 of industry (‘Wool shed’; Soap Works’) and entertainment (‘Skittle Alley’). In reality, another Plan (No.1303) shows Chinese Gardens bordering the Yarra on the Kew side and buildings in Young Street.melbourne and metropolitan board of works, detail plans, mmbw 1302, cartography

"The Melton Viaduct, opened in 1886, is of State heritage significance as a very large and visually distinctive wrought iron, lattice girder trestle bridge over the Werribee River (now Melton Reservoir). It comprises 18.3 and 9.1 metre spans, in a generally alternate arrangement, of total length 375 metres, and standing 38 metres over the Werribee River. Wrought iron small section iron was used to build tension trussed trestle legs, which supported four lines of rivetted wrought-iron deck-type double lattice trusses. It has bluestone abutments and pier bases of coursed rock-faced bluestone with drafted margins. The larger half-piers, now usually submerged in the Melton Reservoir have sharp tapered cutwaters and curved coping at the tops. While designed to carry two rail tracks it has only ever been used as a single track line. Despite several alterations to its deck structure, it remains an outstanding example of a lighter structural design employing open metal trestle supports and metal truss girders. The direct Melbourne to Ballarat railway link of which the Melton viaduct was the major engineering work contributed significantly to the history and development of Victoria. This new link reflected Ballarat’s diversifying economy as well as the commercial and political influence of the metropolis. Construction of the bridge, and the associated large workers camp, were extensively photographed, documenting an important episode in local history. The railway enabled the development of new industries in the Melton area, notably the timber industry and a chaff industry of national importance, greatly facilitated the later transition of the Shire from a pastoral to a farming economy, and struck a major blow to Melton township’s era as a wayside town servicing Ballarat road (especially coach) traffic".

The site of the bridge is nearly a mile up the Murray from the Hume Reservoir Quarry. Its length will be approximately half a mile. There will be nine spans of 269 feet with steel truss girders resting on concrete pillars. Some of the pillars are founded on rock while others will rest on nests of reinforced concrete piles. The foundations and concrete piers are in the hands of the Victorian Constructing Authority and the superstructure in those of the New South Wales Authority.

The Bethanga Bridge was built between 1927 and 1930 as a joint venture between Victoria and New South Wales and was a key element of the River Murray Waters Agreement. It consists of nine spans of 82 metres long. Each span is supported between double reinforced concrete pylons and a riveted steel camel back Pratt truss. The overall span of the bridge is a length of 752 metres. It was completed in 1929 at a cost of £194,000. The road deck was initially constructed from timber but was replaced in 1961 with a concrete waffle slab deck 7.7metres wide. In 1961 the bridge deck and truss structure were raised 300 millimetres to allow for the enlargement of the lake. The bridge was designed in NSW by road engineer Percy Alan and the trusses were built by the Charles Ruwolt Pty. Ltd. Charles Ruwolt Pty. Ltd. was originally established by Charles Ruwolt as a foundry at Wangaratta in 1902 and transferred its operations to Richmond, Melbourne in 1914. By 1938 it had become one of the biggest engineering companies in Australia. After Charles Ruwolt’s death in 1946, Vickers Ltd. acquired the company and in 1948 the firm became known as Vickers Ruwolt Pty. Ltd. Because of the Bethanga Bridge’s unique location, over the waters of a dam with the border running down the centre of the body of water, the Bethanga Bridge is the only built structure shared by both Victoria and New South Wales. As the border of New South Wales aligns with the southern bank of the Murray River all of the other bridges along its length are deemed to be in New South Wales. The Bethanga Bridge is listed on both the New South Wales State Heritage Register and the Victorian Heritage Database. In 2015 the Bethanga Bridge was nominated for a heritage award by the Institution of Engineering Australia.These images are significant because they document the construction of a bridge which links Victoria and New South Wales and has been recognised for its historical, technical and engineering significance.A collection of photos documenting the construction of the Bethanga Bridge which links the States of Victoria and New South Wales as part of the construction of the Hume Dam .bethanga bridge, hume dam constuction, charles ruwolt, percy allan engineer

Opened in 1891, the bridge formed part of the Maroondah Aqueduct carrying water from Watts River near Healesville to the reservoir at Preston where it joined Melbourne's metropolitan water system. Covered under Heritage Overlay, Nillumbik Planning Scheme. Published: Nillumbik Now and Then /​ Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p99 Built to supply thirsty Melbourne in the late 19th century, the siphon bridge spanning the Plenty River off Leischa Court, Greensborough, was part of an engineering masterpiece. Opened in 1891, the bridge formed part of the Maroondah Aqueduct carrying water from the Watts River near Healesville to the reservoir at Preston where it joined the metropolitan distribution system. A major link in Melbourne’s water supply, it also had a huge impact on communities, which mushroomed along its route. Named after the Aboriginal word for the area around the Maroondah Reservoir, the Maroondah Aqueduct was fully operational until the 1970s. Since the 1980s the land along parts of the aqueduct have been used for walking and bicycle riding, shaded in places by Monterey Pine trees planted to stabilise the surrounding ground. From 1857 the Yan Yean Reservoir supplied Melbourne’s water but the growing city needed additional catchments.1 In 1886 work began on a weir on the Watts River to enable the aqueduct to carry most of the river water 41 miles (66km) to Melbourne. The aqueduct, built by the Board of Works, is the oldest remaining aqueduct near Melbourne and was probably the first built with concrete.2 Although the aqueduct is now only used between the Maroondah and Sugarloaf Reservoirs, it can still be traced across the Shire. It extends from the Maroondah Reservoir through Christmas Hills, Kangaroo Ground, Research, Eltham, St Helena and then previously wound west through Greensborough to Reservoir.3 Built by horse and manpower the aqueduct gravity fed 25 million gallons (113.6ML) of water a day to Melbourne along a gradient of one foot to the mile. It included 25 miles (41km) of open concrete and brick channel, six miles (10km) of tunnels, and nine miles (15km) of 14 inverted siphons of riveted wrought-iron across creeks. Bricks for the aqueduct were made from clay found near the sites and remains of several kilns can still be found between Kangaroo Ground and Christmas Hills. Building the aqueduct transformed local communities. An abattoir was established at Christmas Hills. Grog shanties and labourers’ camps sprang up and local courts dealt with cases of ‘petty pilfering and boisterous behaviour’.4 The Kangaroo Ground school population jumped to 91, crammed into a room with one teacher. Miners who built the tunnels camped just north of Churinga in Greensborough – then called Tunnel Hill Camp – and adjacent to the Evelyn Arms Hotel. The miners’ high spirits were sometimes quenched in horse troughs or by a ‘welt under the ear and kick on the behind’ as the local constable calmed them down rather than lock them up.5 But the growing city of Melbourne needed more water, so the O’Shannassy catchment, east of Warburton, was added to the system in 1914. In 1920 work began on the present concrete Maroondah Dam one mile (1.6km) from the weir on the Watts River. The aqueduct capacity was thus doubled to 50 million gallons (227ML) a day.6 Intense land development threatened to pollute the open water supply, so channel sections were replaced with large pipes. In the late 1960s a large water main was built from the tunnel outlet at Research and extended through St Helena and Greensborough, so this section of the aqueduct was taken out of use. Long sections of the unused open channels in Greensborough and Bundoora were destroyed, but the old channel in Research and Eltham North remained largely intact. In the 1970s, the Sugarloaf Reservoir was constructed, inundating 445 hectares of land in Christmas Hills. Sugarloaf was officially opened in 1980 and serves as a water storage and treatment plant supplying Melbourne. In the early 1980s pipes replaced the section from Sugarloaf Reservoir to the tunnel entrance at Kangaroo Ground. The Research-Kangaroo Ground tunnel operates as part of the pipeline system.This collection of almost 130 photos about places and people within the Shire of Nillumbik, an urban and rural municipality in Melbourne's north, contributes to an understanding of the history of the Shire. Published in 2008 immediately prior to the Black Saturday bushfires of February 7, 2009, it documents sites that were impacted, and in some cases destroyed by the fires. It includes photographs taken especially for the publication, creating a unique time capsule representing the Shire in the early 21st century. It remains the most recent comprehenesive publication devoted to the Shire's history connecting local residents to the past. nillumbik now and then (marshall-king) collection, maroondah aqueduct, pipe bridge, siphon bridge
