Fredriksdalsbron
Fredriksdalsbron is a bridge in central Stockholm, Sweden. Serving the light rail line Tvärbanan, it stretches north from the station west of the Gullmarsplan metro station, immediately makes a sharp eastward turn to plunge under two other bridges, Skanstullsbron and Johanneshovsbron, to continue eastward over a viaduct leading down to the station Mårtensdal in the newly built suburb Hammarby sjöstad. During the planning process the project name "Kvarnbron" (''Mill Bridge'') was used. The bridge was built by Nordic Construction Company (NCC) in 2000–2002 as the first part of an extension of the light rail. 379 metres in length, it rests on 15 pillars of which 2 are anchored into the bedrock while the others are steel point-bearing piles. The bridge deck is formed as a non-tensioned reinforced concrete tray rounded underneath.PDF) Abutments and revetments are dressed in slate. The maximum span is 30 metres, and the width varies from 9.4 to 11.4 metres. The longest pill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johanneshovsbron
Johanneshovsbron (Swedish: "The Johanneshov Bridge") is a 756 metres long and 17,9 metres wide road bridge in central Stockholm, Sweden. Overpassing two older bridges, Skansbron and Skanstullsbron, and one newer bridge, Fredriksdalsbron, it connects Södermalm and the tunnel passing under it, Söderledstunneln, to Johanneshov, the district immediately south of the historical city centre, and national road 73, leading out of the city. Brought about by the construction of the tunnel, Johanneshovsbron forms part of one of the major roads passing through the central city, extending north over Centralbron. Running south form the mouth of Söderledstunneln to the west of Skanstull, the bridge runs uphill and somewhat in parallel to Skanstullsbron for some 500 metres before it turns east to pass over its neighbour, between which ramps it finally extends into road 37 underneath the roundabout at Johanneshov. The bridge is made of prestressed concrete, has an average span of 51 metres ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alviksbron
Alviksbron (Swedish for ''The Alvik Bridge'') is a box girder bridge in central Stockholm, Sweden. Stretching over Oxhålssundet, it connects Stora Essingen island to the western suburb Bromma. Built 1996-1998 by the Nordic Construction Company at a cost of 180 million SEK, it has served the Tvärbanan light rail line and pedestrians and bicyclists since its inauguration in August 2000. The name is derived from Alvik, originally a local manor house built in 1819 and demolished in 1930. The bridge is 400 metres in length with a 140-metre central span and a horizontal clearance of 24 metres. The underside of the bridge tie forms an arch intended to make the bridge as slender as possible. The two pillars standing in the water each consist of two thin concrete plates dressed in two-quarters brick with a common concrete foundation. They are illuminated after dark. The construction is pre-tensioned longitudinally by cables, but non-tensioned across. The topside was stretched as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tvärbanan
Tvärbanan is a light-rail line in Stockholm, Sweden. Its name literally translates to ''The transverse line'', as it operates crosswise to the otherwise radial metro and commuter rail lines of Stockholm. It links together several transit lines through its connections with the southern, western and northern subway branches of the Stockholm Metro (''Tunnelbana'') as well as three branches of the Stockholm commuter rail (''Pendeltåg''). The possibility to travel between southern, western and northern greater Stockholm without having to enter the city centre significantly reduces the number of transit passengers, also reducing the number of trains having to pass through the Old Town bottleneck during peak hours. Near Liljeholmen the track is shared with freight traffic for a short section, this being the only place in Sweden where freight traffic and trams share the same track. The tramway is separated from roads in most parts, but there are sections in Gröndal, Sundbyberg and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skansbron
Skansbron (Swedish: "The Fortlet Bridge") is a bascule bridge in central Stockholm, Sweden. Stretching over the canal Hammarbykanalen, it connects the major island Södermalm to the southern mainland district Södra Hammarbyhamnen. Before the lake Hammarbysjön was transformed into a canal in the 1920s, Skanstull, the southern tollgate of the city, was surrounded by fortifications, including a moat over which a simple wooden bridge led into the city. In 1914, the City Council had determined the double traffic load at Slussen, caused by west-east going ships and north-south bound vehicles, would be solved by rerouting the ships south of Södermalm through a canal to be built. Delayed by World War I, the works were finally begun in 1923, and by 1925 a double leaf steel drawbridge was completed. The bridge is 14.9 metres wide with a 10.7-metre wide roadway, and has a horizontal clearance of 12.5 metres. During the construction of the bridge, the north–south traffic flow was c ...

Skanstullsbron
Skanstullsbron (Swedish: "The Fortlet Tollgate Bridge") is a bridge in central Stockholm, Sweden. Overpassing the older bridge Skansbron, it connects the major island Södermalm to the southern district Johanneshov. The first proposal for an elevated bridge stretching over the canal Hammarbykanalen was produced in 1921, before work on the lower Skansbron bridge began in 1923. It remained the favoured bridge design to solve the increasing traffic load of the area during the 1920s and 1930s and was approved by the city council in 1939. World War II led to shortage of both finance and material, but work was started in 1944 and the new bridge was inaugurated in 1947. Skanstullsbron is a concrete double viaduct, with one bridge for vehicles and pedestrians and the other for the metro. Its total length is 574 metres of which 403 metres consists of the 16 spans of the southern beam bridge. The three central spans, 118, 112, and 106 metres long, offer a maximum horizontal clearance of 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Bridges In Stockholm
This is a list of some of the most notable bridges and viaducts in Stockholm, starting with those located closest to the city centre. Many more bridges and viaducts could, of course, be added, including those on the rail and motorway networks, and the many grade-separated junctions in the suburbs which are a product of postwar city planning.

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges In Stockholm
A bridge is a structure built to Span (engineering), 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. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces ...

Gröndalsbron
Gröndalsbron ( sv, The Gröndal bridge) are two bridges in central Stockholm, Sweden, connecting the island Stora Essingen to the southern mainland district Gröndal. The older bridge, inaugurated in 1967, forms a 460-metre section of the Essingeleden motorway, of which 260 metres constitute the bridge, divided into three pre-stressed concrete frames, 70, 120, and 70 metres in length. Due to several ramps connecting to the bridge the width varies from 38 to 45 metres, while the horizontal clearance is 26 metres throughout the entire structure. The second bridge, inaugurated in 2000, forms part of the Tvärbanan light rail line and is a 120 metres long pre-stressed concrete box girder bridge. After its inauguration, slip cracks have been discovered in the bridge, a discovery which was covered up for at least a year and the following revelation in media became a main local news event for some time. The bridge has since been reinforced and is still in operation. See also * L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for ex ...
