A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the turning span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
A bascule bridge is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed.
The Main North Line is a major railway in New South Wales, Australia. It runs through the Central Coast, Hunter and New England regions.

The Port River is part of a tidal estuary located north of the Adelaide city centre in the Australian state of South Australia. It has been used as a shipping channel since the beginning of European settlement of South Australia in 1836, when Colonel Light selected the site to use as a port. Before colonisation, the Port River region and the estuary area were known as Yerta Bulti by the Kaurna people, and used extensively as a source of food and plant materials to fashion artefacts used in daily life.

Australians generally assumed in the 1850s that railways would be built by the private sector. Private companies built railways in the then colonies of Victoria, opened in 1854, and New South Wales, where the company was taken over by the government before completion in 1855, due to bankruptcy. South Australia's railways were government owned from the beginning, including a horse-drawn line opened in 1854 and a steam-powered line opened in 1856. In Victoria, the private railways were soon found not to be financially viable, and existing rail networks and their expansion was taken over by the colony. Government ownership also enabled railways to be built to promote development, even if not apparently viable in strictly financial terms. The railway systems spread from the colonial capitals, except in cases where geography dictated a choice of an alternate port.
The first railway in colonial South Australia was a horse-drawn tramway from the port of Goolwa on the Murray River to an ocean harbour at Port Elliot in 1854. Today the state has 1,600 mm broad gauge suburban railways in Adelaide, a number of country freight lines, as well as key 1,435 mm standard gauge links to other states.
Port Adelaide is a port-side region of Adelaide, approximately 14 kilometres (8.7 mi) northwest of the Adelaide CBD. It is also the namesake of the City of Port Adelaide Enfield council, a suburb, a federal and state electoral division and is the main port for the city of Adelaide. Port Adelaide played an important role in the formative decades of Adelaide and South Australia, with the port being early Adelaide's main supply and information link to the rest of the world. Its Kaurna name, although not officially adopted as a dual name, is Yartapuulti.
The Bridgewater Bridge is a road and rail bridge that carries the Midland Highway and South Railway Line across the Derwent River in Hobart, Tasmania, Australia.

Fort Glanville Conservation Park is a protected area located in the Australian state of South Australia located in Semaphore Park, a seaside suburb of Adelaide consisting of a functional 19th century fort listed on the South Australian Heritage Register and some adjoining land used as a caravan park. The fort was built after more than 40 years of indecision over the defence of South Australia. It was the first colonial fortification in the state and is the best preserved and most functional in Australia. Fort Glanville was designed by Governor Major General Sir William Jervois and Lieutenant Colonel Peter Scratchley, both important figures in early Australian colonial defence. When built it was designed to defend both Semaphore's anchorage and shipping entering the Port River from naval attack.

The Milang railway line was a branch line, now closed, of the former South Australian Railways that left the mainline to Victor Harbor at the farming locality of Sandergrove, 9 km (6 mi) south of Strathalbyn and 89.7 km (55.75 mi) by rail from Adelaide. From there it proceeded in a south-easterly direction for 13.1 km (8.1 mi) to the riverport of Milang on Lake Alexandrina, in the estuary of the River Murray. The line was opened on 17 December 1884; it was formally closed on 17 June 1970. The route is now a "rail trail" that is popular with hikers. The precincts of the former Milang station house a railway museum that includes an innovative locomotive driving simulator for visitors to operate.
