The Hawkesbury River railway bridge is a heritage-listed railway bridge in New South Wales, Australia that carries the Main North railway line across the Hawkesbury River. It is located just north of the town of Brooklyn on the northern outskirts of Sydney. The railway bridge was to be the last link in a railway network that linked the state capitals Adelaide, Melbourne, Sydney and Brisbane and was a major engineering feat at the time. The original railway bridge was built in 1889 and replaced by the current bridge in 1946. The 1946 bridge was added to the New South Wales State Heritage Register on 2 April 1999.
The Spit Bridge, a steel and concrete girder bridge with a bascule lift span across the Middle Harbour, is located 10 kilometres (6.2 mi) northeast of the central business district in Sydney, New South Wales, Australia. The bridge carries The Spit Road (A8) from a point called The Spit, and connects the suburbs of Mosman, on the south bank and Seaforth, on the north bank.
The South Western Railway, also known as the South West Main Line, is the main railway route between Perth and Bunbury in Western Australia.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.
The Hillsborough River Bridge is a bridge crossing the Hillsborough River estuary between Charlottetown and Stratford in Queens County, Prince Edward Island. The current road bridge, built in 1962, replaced a 1905 rail bridge crossing the same span which was known by the same name.
Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure.
Screw piles, sometimes referred to as screw-piles, screw piers, screw anchors, screw foundations, helical piles, helical piers, or helical anchors are a steel screw-in piling and ground anchoring system used for building deep foundations. Screw piles are typically manufactured from high-strength steel using varying sizes of tubular hollow sections for the pile or anchors shaft.
The Surtees Bridge is a road bridge carrying the A66(T) road east west across the River Tees near Thornaby-on-Tees in the borough of Stockton-on-Tees in the north east of England. The bridge is situated one kilometre upriver from Stockton town centre, just upriver of Surtees Rail Bridge – a rail bridge carrying the Tees Valley Line. Built at a cost of £14.3 million the bridge replaces an earlier Surtees Bridge (1981) that showed signs of distress resulting from excessive settlement.
Bunbury Bridge was a single-track, timber railway bridge in East Perth in Western Australia. The bridge crossed the Swan River near Claise Brook and was built for passenger and freight traffic to Bunbury on the South Western Railway, and was also part of the Armadale railway line.
The Nepean River railway bridge is a heritage-listed railway bridge that carries the Main Southern railway line across Menangle Road and the Nepean River located at the outer south-western Sydney settlement of Menangle in the Wollondilly Shire local government area of New South Wales, Australia. It was designed by John Whitton as the Engineer-in-Chief, of the New South Wales Government Railways and NSW Department of Public Works. The railway bridge was built in 1863 by Messers Peto, Brassey and Betts. It is also known as Menangle rail bridge over Nepean River and Menangle Railway Bridge. The property was added to the New South Wales State Heritage Register on 2 April 1999.
Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be able to withstand the weight of these structures and the applied loads. Geohazards must also be taken into account. The need for offshore developments stems from a gradual depletion of hydrocarbon reserves onshore or near the coastlines, as new fields are being developed at greater distances offshore and in deeper water, with a corresponding adaptation of the offshore site investigations. Today, there are more than 7,000 offshore platforms operating at a water depth up to and exceeding 2000 m. A typical field development extends over tens of square kilometers, and may comprise several fixed structures, infield flowlines with an export pipeline either to the shoreline or connected to a regional trunkline.
Clackline Bridge is a road bridge in Clackline, Western Australia, 77 kilometres (48 mi) east of Perth in the Shire of Northam, that carried the Great Eastern Highway until 2008. It is the only bridge in Western Australia to have spanned both a waterway and railway, the Clackline Brook and the former Eastern Railway alignment. The mainly timber bridge has a unique curved and sloped design, due to the difficult topography and the route of the former railway. The bridge was designed in 1934 to replace two dangerous rail crossings and a rudimentary water crossing. Construction began in January 1935, and was completed relatively quickly, with the opening ceremony held in August 1935. The bridge has undergone various improvement and maintenance works since then, including widening by three metres (10 ft) in 1959–60, but remained a safety hazard, with increasing severity and numbers of accidents through the 1970s and 1980s. Planning for a highway bypass of Clackline and the Clackline Bridge began in the 1990s, and it was constructed between January 2007 and February 2008. The local community had been concerned that the historic bridge would be lost, but it remains in use as part of the local road network, and has been listed on both the Northam Municipal Heritage Inventory and the Heritage Council of Western Australia's Register of Heritage Places.
Matagarup Bridge is a suspension pedestrian bridge crossing over the Swan River in Perth, Western Australia.
