As of 2021, Australia was the 12th-largest national economy by nominal GDP, the 18th-largest by PPP-adjusted GDP, and was the 25th-largest goods exporter and 20th-largest goods importer. Australia took the record for the longest run of uninterrupted GDP growth in the developed world with the March 2017 financial quarter. It was the 103rd quarter and the 26th year since the country had a technical recession. As of June 2021, the country's GDP was estimated at A$1.98 trillion. The Australian economy is dominated by its service sector, which in 2017 comprised 62.7% of the GDP and employed 78.8% of the labour force. Australia has the tenth-highest total estimated value of natural resources, valued at US$19.9 trillion in 2019. At the height of the mining boom in 2009–10, the total value-added of the mining industry was 8.4% of GDP. Despite the recent decline in the mining sector, the Australian economy had remained resilient and stable and did not experience a recession from 1991 until 2020. A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.
