The Penrith Whitewater Stadium is located near Sydney, Australia. It is an artificial whitewater sporting facility which hosted the canoe/kayak slalom events at the 2000 Summer Olympics in Sydney. The facility is part of the Penrith Lakes Scheme, which is converting open-pit sand and gravel mines into lakes for recreation. It is close to Cranebrook and is adjacent to the Sydney International Regatta Centre. These lakes are not filled via the Nepean River, but are filled via rain water and ground water. The operation of the facility aerates the water and improves water quality in the flat water rowing and canoeing course. The course is in the shape of a massive 'U', 320 metres in length, between 0.8 and 1.2 metres deep and between eight and 12 metres wide. The overall drop from top to bottom is 5.5 metres. During events a conveyor belt is used to take boats, and their occupants, from the finishing pool back to the start. As the course has been built in a relatively flat area (flood plain), it has been built up and landscaped to create the sloping course necessary for the required rapids. Five of the six available 300-kilowatt pumps lift the water from the bottom to the start of the course, at the rate of 14 m³/s. The channel is constructed from concrete with sloping sides. By setting river pebbles into the concrete an effect to make the course look like a natural river has been created. Large immovable rocks shape the course, as well as movable obstacles which may be used for varying the difficulty of the course and for fine-tuning of the rapids. The total cost of construction was $AU6 million, of which $1.5 million was paid by Penrith City Council, $1.5 million by the International Canoe Federation (including $300,000 by Australian Canoeing) and $3 million by the Government of New South Wales. The facility, which includes a cafe, is a popular recreational area, offering large rubber raft rides, as well as individual kayaking/canoeing. It is regularly used for local, national and international canoeing/slalom events. It is accessed via McCarthys Lane, which runs off Castlereagh Road, Cranebrook. It served as the host venue for the 2005 ICF Canoe Slalom World Championships. It also hosted the 2014 Junior/U-23 ICF Canoe Slalom World Championships. On 1 July 2023, the NSW Office of Sport took over operation of venue.

Victoria Bridge (Penrith)
Victoria Bridge (Penrith)

The Victoria Bridge (Penrith), also known as the Victoria Bridge over the Nepean River and officially known as The Nepean Bridge, is a heritage-listed former railway bridge and now wrought iron box plate girder road bridge across the Nepean River on the Great Western Highway in the western Sydney suburb of Penrith in the City of Penrith local government area of New South Wales, Australia. The bridge was designed by John Whitton, the Engineer–in–Chief of New South Wales Government Railways, and built from 1862 to 1867 by William Piper, Peto Brassey and Betts (superstructure), William Watkins (piers). It is also known as Victoria Bridge, The Nepean Bridge and RTA Bridge No. 333. It was added to the New South Wales State Heritage Register on 27 May 2016.The bridge initially carried rail and horse–drawn traffic, and was converted in 1907 to exclusively carry the Great Western Highway. The bridge is managed by Transport for NSW. The bridge is the oldest surviving crossing of the Hawkesbury–Nepean River. As at 2009, Roads and Maritime Services estimated that Victoria Bridge carried an average daily traffic of 25,000 vehicles per day.Until 1856 travelers who wished to cross the Nepean River were required to use either the Emu Ford or a punt that was located south of the present day Victoria Bridge on Punt Road. This arrangement meant that in times of flood, travellers were often delayed at Penrith for days or even weeks waiting to cross the river. A small village developed near Emu Ford to cater to the people waiting to cross the river. With the discovery of gold west of the Great Dividing Range the flow of people, produce and animals through Penrith and across the river increased dramatically. It was no coincidence that attempts were made to build a permanent structure across the river, resulting in two timber road bridges located near to the eventual Victoria Bridge site being constructed.Prior to the construction of the Victoria Bridge, a punt service was located at the site of the bridge. Following the discovery of gold in the west of the Great Dividing Range demand for a permanent river crossing increased. A timber bridge was constructed with private funds, charging a toll for its use. In 1850 the Government, reacting to lobbying by Penrith locals, passed an Act authorising the construction of a bridge at the western end of Jamison Road. This scheme never went ahead. A second Act was passed in 1851 authorising the formation of a company, allocating A₤6,000 for the construction of the bridge and allowing for the collection of tolls on the bridge. Following this act the Penrith and Nepean Bridge Company was formed. A further Act in 1854 increased the allocated funds to ₤20,000. The first directors of the Penrith and Nepean Bridge Company were local entrepreneurs Robert Fitzgerald, James Thomas Ryan, Edwin Rouse, John Perry, Charles York, Henry Hall, Alexander Fraser. Construction of the bridge was under the supervision of David McBeth, a Scottish surveyor.The bridge, completed in December 1855, was 213 metres (700 ft) long and 8 metres (26 ft) wide, becoming the first bridge across the Nepean River in the area. McBeth received a ₤200 bonus on top of his ₤300 salary for the timely completion of the works, the toll rights for the first year were sold by the Penrith and Nepean Bridge Company for ₤2,250 and traffic flowed across the bridge. The successful Penrith and Nepean Bridge Company held a celebration party costing approximately ₤1,000 on the new bridge to celebrate its completion. Opened in January 1856, the bridge was destroyed by floods in 1857, and again rebuilt. Surviving the February 1860 flood, it was again destroyed in May 1860.Unfortunately this success did not last long. In August 1857 a flood carried away the four centre spans, no doubt due to the poor security of the mid-stream timber piles which reportedly were frayed like mop heads where McBeth had attempted to drive them into rock. McBeth had lacked experience and knowledge in bridge building and although the piles close to the bank went in easily, the mid-stream timber piles had struck rock and failed to achieve a secure penetration.The Penrith and Nepean Bridge Company decided to rebuild the bridge and employed an engineer named Moriarty to supervise the works. The construction contract was awarded to William Lockhart for ₤9,000. The piles that remained from the first bridge were utilised in the new bridge design, against the advice of both Lockhart and Moriarty. The new bridge was of a different, stronger design than the first and construction was completed in good time with the toll rights for one year selling for ₤2,850. The bridge withstood its first flood, but in 1860 the most devastating flood in New South Wales history until that time washed away the entire superstructure and deposited it on a bank down river. The structure was almost intact. Had the piles been replaced as originally suggested by the engineer and builder, the bridge might well have survived the flood. The Penrith and Nepean Bridge Company was ruined by the destruction of the bridge and the directors lost large sums of money. Following the destruction of this second bridge the Government supplied two punts to convey people and goods across the river. The punts were irreparably damaged by a flood in 1867.The loss of the punts coincided with a period in which the Great Western Railway was in the advanced planning stages, including plans for the construction of a bridge over the Nepean River to link Penrith with Bathurst in the west, as part of the Penrith to Weatherboard Line (later Wentworth Falls). It was decided that the required bridge would carry both a railway line and a single lane of road over the river, as a temporary solution.Victoria Bridge was designed by the Engineer-in-Chief of Railways in NSW, John Whitton and checked in Britain by his brother-in-law and renowned railway engineer John Fowler. Victoria Bridge was designed to carry two railway tracks as it was intended that the road on the bridge be only a temporary arrangement. The flood of 1860 that had carried off the previous bridge influenced Whitton to raise the bridge deck by two metres (six feet) after witnessing the power of high flood waters.The design of the bridge uses half through girders which are actually tall boxes made of riveted wrought iron plates was driven by the need to keep the underside of the bridge as shallow as possible to maximise headroom for flood clearance. The configuration of their boxes with their tall web plates, and upper box for lateral stability, reflected cutting-edge design for the period. It utilised cutting edge of structural technology, using principles developed by Robert Stephenson in his design of the Britannia Bridge and the Conwy Railway Bridge in Wales, Thomas Telford and others who, by testing and theoretical work, developed techniques to prevent plate buckling by providing frequent vertical stiffeners, and sideways buckling of girders members by adding torsionally stiff boxes at the top and bottom. The first deep box girder bridge was designed by Stephenson and built across the Menai Strait in 1850. It was provided with suspension towers in case the deck was insufficiently strong and stiff, but the cables were never installed.The construction contract for Victoria Bridge was split into several parts. One contract for the construction of the piers was awarded to William Tyler in 1862. He commenced work but flooding in 1863 and 1864 damaged his equipment and contributed to his abandonment of the contract in August 1864. The contract was subsequently awarded to W. Watkins for the sum of ₤44,658. He completed the work before the agreed completion date and avoided the ₤50 per week penalty he would have incurred had he not delivered on time.The ironwork for the bridge was supplied by Peto, Brassey and Betts of Birkenhead, England for ₤41,750. The same firm had supplied the ironwork for the Menangle Railway Bridge constructed on the Nepean River in 1863 and now the oldest surviving bridge on the NSW railway system. The timber approach viaduct for the Victoria Bridge was constructed by Mr Baillie at a cost of ₤8,716. Other small contracts for earthworks were also made bringing the total cost of the 1100 tonne iron bridge to approximately ₤110,000.The Nepean Bridge (Victoria Bridge) was completed on 6 June 1867, two weeks before the greasiest flood ever recorded in the district passed under it. The Great Flood of 1867 damaged the western timber approaches and washed away a portion of the spans and river bank. The main spans however withstood this first major test and the flood waters did not reach the underside of the deck. Temporary repair work took about ten days to completed and as a result the bridge was opened to trains on 11 July 1867. The damaged timber viaduct was replaced by a shorter wrought iron box-girder span manufactured by the Thames Iron Company, Blackwall, England. During the construction of the spans the punt was used for road traffic until the bridge was re-opened to road traffic in 1869. The Victoria Bridge was considered to be of such modern design that it was featured in the "Modern Examples of Road and Railway Bridges" by Maw and Dredge in 1872.Victoria Bridge had a significant impact on the local economy. Prior to its opening Penrith station formed the rail head of the western line, making Penrith a trade hub. The introduction of the road across the Nepean River diminished the business in the town previously brought in by travellers delayed in Penrith by poor river conditions. Conversely the opening of the bridge and the road and railway to the west enabled the growth of centres west of the mountains and the tourist industry of the Blue Mountains to become established.Following the increase in rail traffic on the Great Western Railway and the increase in the weight of locomotive engines, options were considered for the duplication of the railway line and of the Victoria Bridge. The possibility of using Victoria Bridge to carry two rail lines was considered. But this would have required the strengthening of the bridge by constructing intermediate piers between the existing piers of the bridge, thus halving the length of the spans. This technique had been applied to Victoria Bridge's sister structure the Menangle Bridge in 1907. It was however decided that the construction of a second bridge alongside the Victoria Bridge would be more appropriate and construction on a steel truss bridge was undertaken. The piers of the new bridge lined up with Victoria Bridge's existing piers in an attempt to minimise stresses on the structures during high river flows. In 1907 the railway bridge that now stands alongside Victoria Bridge was completed. With its completion the Victoria Bridge was converted to carry two lanes of traffic and a footway while the new bridge carried two rail lines. Originally it took one railway line and a road across the river, however in 1907 another bridge was constructed a few metres to the north which thenceforth took two railway lines across the river, and the original bridge reverted to road and pedestrian use only.In the mid-1930s the timber approach spans of the bridge were discovered to be heavily deteriorated through termite attack and the approach spans were replaced with reinforced concrete trestles and a concrete deck supported by rolled steel joists (RSJs).The site of Victoria Bridge has long been a centre of recreation in the Penrith region. From the 1850s it has been used for national and international rowing competitions. The bridge is significant in the development of the colony of NSW as it allowed the railway, which previously terminated at Penrith, to reach the Railway Blue Mountains and beyond, as well as providing continuous road passage across the river using the Great Western Highway.
