41-563: The Story Bridge is a heritage-listed steel cantilever bridge spanning the Brisbane River that carries vehicular, bicycle and pedestrian traffic between the northern and the southern suburbs of Brisbane , Queensland , Australia. It is the longest cantilever bridge in Australia. The road across the bridge is named Bradfield Highway. The bridge connects Fortitude Valley to Kangaroo Point . The Story Bridge opened in 1940 and

82-465: A paraschist , while if the protolith was an igneous rock, the schist will be described as an orthoschist . Mineral qualifiers are important when naming a schist. For example, a quartz-feldspar-biotite schist is a schist of uncertain protolith that contains biotite mica, feldspar , and quartz in order of apparent decreasing abundance. Lineated schist has a strong linear fabric in a rock which otherwise has well-developed schistosity. Schistosity

123-698: A transporter bridge further downstream near New Farm . In 1926 Kangaroo Point was recommended by the Brisbane City Council's Cross River Commission. Subsequently, the bridge was constructed as a public works program during the Great Depression . The cost was to be no more than £1.6 million. Before the opening of the Sydney Harbour Bridge in 1932 the Government of Queensland asked John Bradfield to design

205-416: A consortium of two Queensland companies, Evans Deakin and Hornibrook Constructions , won the tender with a bid of £1,150,000. Construction on the bridge began on 24 May 1935, with the first sod being turned by the then Premier of Queensland , William Forgan Smith . Components for the bridge were fabricated in a purpose-built factory at Rocklea . There are 1.25 million rivets (metal pins or bolts) in

246-713: A historic house requires consulting the urban planning administration bureau, and the real estate administration bureau. As of 31 June 2011, there are 287 declared historic houses in Hangzhou, proclaimed as 5 batches. In the near future, it is going to issue the sixth batch which includes 51 historic houses.

287-457: A medium grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs . Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a mica schist ). Where the type of the original rock (the protolith ) is discernible, the schist is usually given a name reflecting its protolith, such as schistose metasandstone . Otherwise,

328-440: A mica schist. Early stages of metamorphism convert mudstone to a very fine-grained metamorphic rock called slate , which with further metamorphism becomes fine-grained phyllite . Further recrystallization produces medium-grained mica schist. If the metamorphism proceeds further, the mica schist experiences dehydration reactions that convert platy minerals to granular minerals such as feldspars, decreasing schistosity and turning

369-660: A new bridge in Brisbane . The Queensland Government appointed John Bradfield on 15 December 1933 as consulting engineer to the Bureau of Industry who were in charge of the construction of the bridge. In June 1934 Bradfield's recommendation of a steel cantilever bridge was approved. The design for the bridge was based heavily on that of the Jacques Cartier Bridge in Montreal , completed in 1930. On 30 April 1935

410-614: A popular tourist attraction. A picture of the bridge featured on Brisbane Bitter . Similar to many large bridges such as the Golden Gate Bridge in San Francisco, Brisbane's Story Bridge has become notorious as a suicide hotspot. Following two high-profile murder-suicides from the bridge in 2011 and 2012, Brisbane Lord Mayor Graham Quirk announced plans to install free telephones linked to suicide prevention hotlines. On 6 February 2013, Quirk announced plans to install

451-405: A result of medium-grade metamorphism, they can vary greatly in mineral makeup. However, schistosity normally develops only when the rock contains abundant platy minerals, such as mica or chlorite . Grains of these minerals are strongly oriented in a preferred direction in schist, often also forming very thin parallel layers. The ease with which the rock splits along the aligned grains accounts for

492-551: A schist are typically from 0.25 to 2 millimeters (0.01 to 0.08 in) in size and so are easily seen with a 10× hand lens . Typically, over half the mineral grains in a schist show a preferred orientation. Schists make up one of the three divisions of metamorphic rock by texture , with the other two divisions being gneiss , which has poorly developed schistosity and thicker layering, and granofels , which has no discernible schistosity. Schists are defined by their texture without reference to their composition, and while most are

533-719: A three-metre-high safety barrier. Overall the plan cost about $ 8.4 million and was completed in December 2015. The bridge was listed on the Queensland Heritage Register in 1992. In 1988, the bridge received a Historic Engineering Marker from Engineers Australia . In 2009 as part of the Q150 celebrations, the Story Bridge was announced as one of the Q150 Icons of Queensland for its role as

574-592: Is developed at elevated temperature when the rock is more strongly compressed in one direction than in other directions ( nonhydrostatic stress ). Nonhydrostatic stress is characteristic of regional metamorphism where mountain building is taking place (an orogenic belt ). The schistosity develops perpendicular to the direction of greatest compression, also called the shortening direction, as platy minerals are rotated or recrystallized into parallel layers. While platy or elongated minerals are most obviously reoriented, even quartz or calcite may take up preferred orientations. At

615-524: Is known to have experienced greenschist facies metamorphism , for example in the northern Andes . Metamorphosis of felsic volcanic rock , such as tuff, can produce quartz- muscovite schist. In geotechnical engineering a schistosity plane often forms a discontinuity that may have a large influence on the mechanical behavior (strength, deformation, etc.) of rock masses in, for example, tunnel , foundation , or slope construction. A hazard may exist even in undisturbed terrain. On August 17, 1959,

656-419: Is unknown and its mineral content is not yet determined. Otherwise, the modifier schistose will be applied to a more precise type name, such as schistose semipelite (when the rock is known to contain moderate amounts of mica) or a schistose metasandstone (if the protolith is known to have been a sandstone ). If all that is known is that the protolith was a sedimentary rock, the schist will be described as

1107-451: The Story Bridge. During its construction, work sometimes continued 24 hours per day. The bridge has only one pier on the northern bank but two piers on the lower southern bank, one to bear the weight (the main pier) and, further to the south, one to prevent the bridge from twisting (the anchor pier). There was no need for an anchor pier on the northern bank as the bridge was anchored into schist cliff face. The primary challenge in constructing

1148-489: The annual Riverfire fireworks display and is illuminated at night. In 1990, road traffic was halted so pedestrians could celebrate the 50th anniversary of the bridge's construction. The bridge was again closed to road traffic on 5 July 2015 to celebrate the 75th anniversary. The celebration attracted almost 75,000 visitors to the bridge who enjoyed food, drink and entertainment as they walked across lanes usually reserved for vehicles. Bridge climbs began in 2005 and have become

1189-460: The bridge was the southern foundations that went 40 metres (130 ft) below ground level. It was not possible to excavate to that level as water from the river would rapidly seep in. So a pneumatic caisson technique had to be used. As men were working under pressures of up to 4 times normal air pressure, a decompression period of almost 2 hours was needed at the end of each shift to avoid the bends . An on-site air lock hospital successfully treated

1230-546: The bridge's construction. The bridge carries an average of 97,000 vehicles each day. The Story Bridge carries three lanes of traffic in either direction as well as a shared pedestrian and cycle way flanking each side. The road on the bridge is called the Bradfield Highway. It is not to be confused with the Bradfield Highway that spans the Sydney Harbour Bridge . Initially a toll of sixpence (5 cents)

1271-576: The bridge. Construction of a new underpass was begun on the southside in 2023 to facilitate access to the Kangaroo Point Green Bridge . Until it was completed, the bridge was known as the Jubilee Bridge in honour of King George V . It was opened on 6 July 1940 by Sir Leslie Orme Wilson , Governor of Queensland and named after John Douglas Story , a senior and influential public servant who had advocated strongly for

1312-410: The ground. On 7 February 1939, Alfred William Jackson fell from the bridge into the river. Although pulled from the water alive, he died 4 hours later in hospital without regaining consciousness. On 6 December 1939, Arthur McKay (Max) Wharton was hit by a piece of equipment on a nerve that made him faint, falling from the bridge to the water; 18 months earlier Wharton saved another worker from falling from

1353-412: The microscopic level, schistosity is divided into internal schistosity , in which inclusions within porphyroblasts take a preferred orientation, and external schistosity , which is the orientation of grains in the surrounding medium-grained rock. The composition of the rock must permit formation of abundant platy minerals. For example, the clay minerals in mudstone are metamorphosed to mica, producing

1394-465: The names of the constituent minerals will be included in the rock name, such as quartz-felspar-biotite schist . Schist bedrock can pose a challenge for civil engineering because of its pronounced planes of weakness . The word schist is derived ultimately from the Greek word σχίζειν ( schízein ), meaning "to split", which refers to the ease with which schists can be split along the plane in which

1435-421: The northern side (completed 10 July 1972). Resurfacing works were undertaken in 1994. The Story Bridge was closed to traffic from midnight of Friday 3 January 2014 until 5.30 a.m. Monday, 6 January 2014, for essential maintenance work of resurfacing all six lanes. Closure for maintenance occurred again from 9 p.m. Friday 27 April 2018 until 5 a.m. Monday 30 April 2018. The Story Bridge features prominently in

1476-490: The platy minerals lie. Before the mid-19th century, the terms slate , shale and schist were not sharply differentiated by those involved with mining. Geologists define schist as medium-grained metamorphic rock that shows well-developed schistosity. Schistosity is a thin layering of the rock produced by metamorphism (a foliation ) that permits the rock to easily be split into flakes or slabs less than 5 to 10 millimeters (0.2 to 0.4 in) thick. The mineral grains in

1558-488: The rock into a gneiss. Other platy minerals found in schists include chlorite, talc, and graphite. Chlorite schist is typically formed by metamorphism of ultramafic igneous rocks, as is talc schist. Talc schist also forms from metamorphosis of talc-bearing carbonate rocks formed by hydrothermal alteration . Graphite schist is uncommon but can form from metamorphosis of sedimentary beds containing abundant organic carbon . This may be of algal origin. Graphite schist

1599-436: The schistosity. Though not a defining characteristic, schists very often contain porphyroblasts (individual crystals of unusual size) of distinctive minerals, such as garnet , staurolite , kyanite , sillimanite , or cordierite . Because schists are a very large class of metamorphic rock, geologists will formally describe a rock as a schist only when the original type of the rock prior to metamorphism (the protolith )

1640-476: Was charged to use the bridge, with toll booths constructed at the southern end of the Bradfield Highway. The toll was removed in 1947. Between 1952 and 1969 trolley-buses operated by the Brisbane City Council used the bridge. Following completion of the bridge, an expressway was constructed on the southern side of the bridge (opened 18 May 1970), and a tunnel/loop was constructed at Kemp Place on

1681-489: Was tolled until 1947. It is named after prominent public servant John Douglas Story . Given the early settlement of Kangaroo Point , there is a long history of residents wanting a bridge between the Brisbane CBD and Kangaroo Point. Even while the first Victoria Bridge was being constructed between North Brisbane and South Brisbane in 1865, several hundred people were petitioning for a second bridge to be built from
