Watchout my 10 Spectacular Movable Bridges that i will never forget when iam traveling

A movable bridge is a bridge that moves to allow passage (usually) for boats or barges. An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passages.

 

  1. Gateshead Millennium Bridge, UKgateshead-i
  2. The Gateshead Millennium Bridge is a pedestrian and cyclist bridge spanning River Tyne in England between Gateshead’s Quays arts quarter on the south bank, and the Quayside of Newcastle on the north bank. The bridge is essentially two graceful curves, one forming the deck and the other supporting it, spanning between the two islands running parallel to the quaysides.

    To allow ships to pass underneath, this whole assembly rotates as a single, rigid structure. As the arch tilts lower, the pathway rises, each counterbalancing the other, and a pathway over the river is formed.

     

    gateshead-3

    link

    The parabolic curves of the deck extend the 105m (344ft) crossing distance to around 120m (394ft), giving enough extra length to provide the required clearance above the water. The appearance of the bridge when in motion leads to it sometimes being called the ‘Blinking Eye Bridge‘ or the ‘Winking Eye Bridge’ since its shape is akin to the blinking of an eye if seen from along the river. Visually elegant when static and in motion, the bridge offers a great spectacle during its opening operation.

    The bridge is operated by six 45 cm (18 inches) diameter Hydraulic rams, three on each side, and each powered by a 55 kW electric motor. Small ships and boats up to 25 meters (82ft) tall can pass underneath. The bridge takes as little as 4.5 minutes to rotate through the full 40° from closed to open, depending on wind speed.

    The construction of the bridge won the architects Wilkinson Eyre the 2002 Royal Institute of British Architects (RIBA) Stirling Prize, the 2003 Gifford IStructE Supreme Award, and in 2005, the Outstanding Structure Award from International Association for Bridge and Structural Engineering (IABSE).

    1. Slauerhoffbrug, Netherlandsslauerhoffbrug-1
    link

    The Slauerhoffbrug is a fully automatic bascule bridge (aka tail bridge) in the city of Leeuwarden in the Netherlands. It uses two arms to swing a section of road in and out of place within the road itself.

    slauerhoffbrug-2

    link

    It is also known as the “Slauerhoffbrug ‘Flying’ Drawbridge”. A tail bridge can quickly and efficiently be raised and lowered from one pylon (instead of hinges). This quickly allows water traffic to pass while only briefly stalling road traffic.

     

    slauerhoffbrug-4

    link

    The deck is 15m by 15m (50x50ft). It is painted in yellow and blue, representative of Leeuwarden’s flag and seal. Slauerhoffbrug is perhaps named after J.J. Slauerhoff, the famous Leeuwarder, Dutch poet.

    The pylon is situated next to the bridge. The skew bridge deck accentuates the asymmetrical shape. The pylon is provided with chases for the ballastblock in open position.

    The robust lift bearing disappears into the road deck. Main girders and cross girders are missing in the construction. The bottom of the bridge deck is flat. [link1, link2, map]

    3. Pont Jacques Chaban-Delmas, France

     

    pont-jacques-1

    link

    The Pont Jacques Chaban-Delmas is a vertical-lift bridge over the Garonne in Bordeaux, France. It was inaugurated on 16 March 2013 by President François Hollande and Alain Juppé, mayor of Bordeaux. Its main span is 110 m (361 ft) long

     

     

    pont-jacques-2

    The bridge has a lift height of approximately 50m (164ft) and it operate roughly 120 times per year for the passage of large vessels to the ports surrounding Bordeaux.

     pont-jacques-3
    The lift span structure has symmetric cross-section and carries four traffic lanes – two mass transport tracks and two outboard sidewalk/bikeways.

    Four, independent pylon towers-one at each corner of the lift span – support the span weight and permit the movement of the counterweights vertically inside each pylon.
    As of 2013, it is the longest vertical-lift bridge in Europe. It is named in honour of Jacques Chaban-Delmas, a former Prime Minister of France and a former mayor of Bordeaux. [link1, link2, map]

    4. Vizcaya Bridge, Spain

    link
    The Vizcaya Bridge is a transporter bridge that links the towns of Portugalete and Las Arenas (part of Getxo) in the Biscay province of Spain, crossing the mouth of the Ibaizabal River.

    link
    People in the area, and even the official website, commonly call it the Puente Colgante (literally “hanging bridge”, used for suspension bridge in Spanish), although its structure is quite different from a suspension bridge.

    link
    The Vizcaya Bridge was built to connect the two banks which are situated at the mouth of the Ibaizabal River. It is the world’s oldest transporter bridge and was built in 1893, designed by Alberto Palacio, one of Gustave Eiffel’s disciples and Elissague.

    link
    The bridge, still in use, is 164m (538ft) long, and its gondola can transport six cars and several dozen passengers in one and a half minutes. It operates every 8 minutes during the day (every hour at night), all year round, with different fares for day and night services, and is integrated into Bilbao’s Creditrans transport system.
    The structure is made of four 61 metre (200ft) towers which are the pillars and lay on the river banks.There are two new visitor lifts installed in the 50 meter (164ft) high pillars of the bridge that allow walking over the bridge’s platform, from where there is a view of the port and the Abra bay. [link, map]

    5. Puente de la Mujer, Argentina

    link
    Puente de la Mujer (Spanish for “Women’s Bridge”) is a rotating footbridge for Dock 3 of the Puerto Madero commercial district of Buenos Aires, Argentina. It is of the Cantilever spar cable-stayed bridge type and is also a swing bridge, but somewhat unusual in its asymmetrical arrangement.

    link
    It has a single mast with cables suspending a portion of the bridge which rotates 90 degrees in order to allow water traffic to pass. When it swings to allow watercraft passage, the far end comes to a resting point on a stabilizing pylon.

    link
    The 170-metre (558ft) pedestrian bridge weighs 800 tonnes, is 6.2m (20ft) wide and is divided into two fixed portions, 25m (82ft) and 32.5m (107ft) long respectively, and a middle section of 102.5 m (336ft) that rotates on a white concrete pylon, allowing vessels to pass in less than two minutes.
    This central section is supported by a steel “needle” with a concrete core, about 34m (112ft) high. The “needle,” inclined at a 39° angle, anchors suspension cables which support the central span. A computer system at the eastern end of the bridge operates the turning mechanism when required. [link, map]

    6. River Hull Footbridge, UK

    link
    The steel River Hull Footbridge (also called Scale Lane Bridge) is the world’s first footbridge that rotates to open or close for river traffic while pedestrians are still on it. The beautiful prefab structure designed by London-based McDowell+Benedetti spans the River Hull in Yorkshire and takes about two minutes to fully open or close. It connects the city center (Hull) with the eastern development, acting as both an important infrastructural urban element and a new civic landmark.

    link
    The footbridge is approximately 16 meters (52.5ft) in diameter and features a series of wheels running on a circular track below the hub that allows it to open and close – depending on the amount of river traffic.

    link
    A full sequence takes about two minutes and moves very slowly at a speed lower than that of the London Eye. Pedestrians and bikers can stay on it while it rotates and experience the river from a whole new perspective.

    Scale Lane Bridge at night link
    The lighting for the bridge was designed by Sutton Vane Associates, who made sure that the energy efficient lights cast a trace over the water at night and create an appearance of the bridge being defined by the point of light from the line of fittings.

    Small points of light emphasize the shape of the bridge and appear when the bridge starts to pivot. To add to the drama, a row of recessed lights turn on while the bridge is moving, creating a unique light show. [link, map]

    7. Hörn Bridge, Germany

    link
    The Hörn Bridge is a folding bridge in the city of Kiel in the German state of Schleswig-Holstein. The bridge spans over the end of the Kiel Fjord (called Hörn) and was designed by Gerkan, Marg and Partners. It is a three-segment bascule bridge with a main span of 25.5 metres (84 ft) that folds in the shape of the letter “N”. The bridge was built in 1997 and did cost DM 16 million.

    link
    The Hörn Bridge is 5 metres (16ft) wide and connects the city centre on the west bank of the Hörn with the Gaarden quarter on the east bank. The pedestrian bridge is especially important for passengers connecting between the Norway Ferry Terminal (Norwegenkai) and the main railway station.

    link
    Many Kielians were skeptical in regard to the design. There were repeated malfunctions of the mechanism upon startup, hence one of its nicknames, the “Klappt-Nix-Brücke” (Folds-not Bridge). In order to ensure crossing for pedestrians and cyclists, a hydraulically operated retractable bridge was built directly adjacent as an interim solution and is still used during repair and maintenance of the folding bridge. The Hörn Bridge is now accepted as a technical masterpiece and has become a tourist attraction.
    Usually the bridge opens once every hour in order to allow small- and medium-sized ships to travel in and out of the Hörn. The bridge offers one of the best panoramic views of the city of Kiel. It is also at the beginning and terminating point of a scenic route: the tourist route from Bremervörde to the Kieler Förde connects approximately 50 different ferries, bridges, ship locks, tidal barriers and maritime museums and its landmarks of the Rendsburg and Osten transporter bridges. [link, map]

    8. Foryd Harbour Bridge, UK

    link
    Foryd Harbour Cycle and Pedestrian Bridge is located in Rhyl – a seaside resort town and community in Denbighshire, situated on the north east coast of Wales, UK. The iconic structure provides a single leaf bascule opening span over the navigable channel, giving unlimited clearance. To balance the lift, the back-span also lifts mirroring its twin.

    link
    A single Duplex stainless steel mast nearly 50m (164ft) tall houses a pulley mechanism and associated lift cables, providing a visual declaration of the bridge’s presence that will be visible from miles around and will also provide a central focus within the harbour.
    The mast is stayed by a system of rigging similar to that seen on many sailing boats. To accommodate the central mast, each deck splits to permit a 3 metre (10ft) walkway on either side. [link]

    9. Submersible Bridges at Corinth Canal, Greece

    Submersible bridge at the eastern terminus of the Corinth Canal link
    The Corinth Canal in Greece cuts through the narrow Isthmus of Corinth and separates the Peloponnesian peninsula from the Greek mainland, connecting the Gulf of Corinth with the Saronic Gulf in the Aegean Sea.

    link
    Built between 1881 and 1893, the Corinth Canal is considered a great technical achievement for its time. Although the canal saves the 700-kilometer (435mi) journey around the Peloponnese, it is too narrow for modern ocean freighters, as it can only accommodate ships of a width of up to 16.5 meters (54ft) and a draught of 7.3 meters (24ft).

    A boat passes over the Submersible bridge at the eastern terminus of the Corinth Canal. link
    Ships can only pass through the canal one at a time on a one-way system. Larger ships have to be towed by tugs. The canal is nowadays mostly used by tourist ships, with 11,000 ships using the canal every year.

    link
    In 1988, two submersible bridges were constructed exist across the Corinth Canal, one at each end, in Isthmia and Corinth. The bridge lowers the bridge deck 8 meters (26ft) below water level to permit waterborne traffic to use the waterway.
    The primary advantage of lowering the bridge instead of lifting it above is that there is no structure above the shipping channel and thus no height limitation on ship traffic. This is particularly important for sailing vessels. Additionally, the lack of an above-deck structure is considered aesthetically pleasing. However, the presence of the submerged bridge structure limits the draft of vessels in the waterway. [link, map]

    10. El Ferdan Railway Bridge, Egypt

    link
    The El Ferdan Railway Bridge, also known as the Al-Firdan Bridge, extends over the Suez Canal, close to the city of Ismailia in the northeast region of Egypt.

    link
    The bridge connects mainland Egypt with the Sinai Peninsula, and measuring 1,100 feet (335m) in length, it’s the world’s longest swing bridge. Both sides of the structure pivot on piers when it’s opening or closing, and thanks to a pair of electric slewing drives, it takes a total of 30 minutes to fully open.

    link
    Unlike other bridges on this list, the El Ferdan Railway Bridge stays open for water traffic, and it’s only closed to allow trains to cross the canal. A consortium of Belgian, German and Egyptian companies designed and built it, and construction was completed in 2001 at a cost of roughly $80 million. The bridge was officially opened on November 14, 2001. [link, map]

    Bonus 1: Barton Swing Aqueduct, UK

    link
    The Barton Swing Aqueduct is a moveable navigable aqueduct in Barton upon Irwell in Greater Manchester, England. It carries the Bridgewater Canal across the Manchester Ship Canal.

    Barton Swing Aqueduct in the closed position link
    The swinging action allows large vessels using the ship canal to pass underneath and smaller narrowboats to cross over the top.

    Barton Swing Aqueduct in the open position link
    The aqueduct, the first and only swing aqueduct in the world, is a Grade II listed building, considered a major feat of Victorian civil engineering. Designed by Sir Edward Leader Williams and built by Andrew Handyside of Derby, the swing bridge opened in 1894 and remains in regular use.

    link
    The aqueduct is a form of swing bridge. When closed, it allows canal traffic to pass along the Bridgewater Canal. When large vessels need to pass along the ship canal underneath, the 1450-tonne (1430-long-ton; 1600-short-ton) and 330-foot (100m) long iron trough is rotated 90 degrees on a pivot mounted on a small purpose-built island.
    Gates at each end of the trough retain around 800 tonnes of water; additional gates on each bank retain water in their adjacent stretches of canal. The aqueduct originally had a suspended towpath along its length, about 9 feet (2.7 m) above the water level of the Bridgewater Canal, which has now been removed. [link, map]

    Bonus 2: M60A1 Armored Vehicle Launched Bridge

    link
    The Armored Vehicle Launched Bridge (US Army vehicle) was designed to launch and retrieve a class 60 bridge. Used during combat, an AVLB is a folding portable bridge that is transported on the top of a tank chassis. The AVLB vehicle carries a crew of two. It is powered by a 750 HP Diesel Engine. The bridge and vehicle total weight is 58 tons.

    link
    The Armored Vehicle Launched Bridge (AVLB) only supports Abrams tank units using a caution crossing at reduced gap length (15 meters or 50ft) and at a reduced crossing speed. The M60A1 Armored Vehicle Launched Bridge entered the Marine Corps inventory in the late 1980s. Current plan has the AVLB in use through 2015 and beyond. The WOLVERINE will replace the AVLB in the Engineer combat vehicle inventory.

    link
    The M60A1 AVLB is an armored vehicle used for launching and retrieving a 60-foot (18.3m) scissors-type bridge. The AVLB consists of three major sections: the launcher, the hull, and the bridge. The launcher is mounted as an integral part of the chassis. The bridge, when emplaced, is capable of supporting tracked and wheeled vehicles with a military load bearing capacity up to Class 60.
    The bridge can be retrieved from either end. The roadway width of the AVLB is 12.5 feet (3.8m). Bridge emplacement can be accomplished in 2 to 5 minutes, and retrieval can be accomplished in 10 minutes under armor protection. When unfolded, it can span up to 60 feet (18.3m) while supporting 70 tons of equipment. The AVLB spans a 15m (50ft) gap for Military Load Class 70, and spans an 18m (60ft) gap for Military Load Class 60. [link]

Many tourist deny their eyes&mind to be fed with 12 Unusual Towers From Around the World i observed&leant.

The towers are tall structures, usually taller than they are wide, often by a significant margin. These slender buildings are generally built to take advantage of their height, and can stand alone on the ground, or as part of a larger structure. Here we have 12 towers that are significantly different from all other towers, and because of that are preferred by many photographers and tourists.

  1. Ivy Тower, Belgium

Gruuthuse Tower is part of the museum and is better known as the Ivy Tower, because it is mostly covered with ivy vines. The tower looks especially nice in the autumn months, when the leaves of ivy takes on different colors (yellow, orange, red, brown…) [map]

2. Guinigi Tower, Italy

guinigi-tower-1

link

The city of Lucca in Tuscany, Italy, is famous for its medieval architecture and intact city walls.  Yet among all of its exquisite buildings one stands out. The Torre Guinigi or Guinigi Tower in English, towers over the city.

 

At the top of the 44.5 meter (146ft) high tower is something of a surprise – a garden containing, of all things, oak trees. High above the city this small wood has provided a haven of peace for centuries.

The tower was built in the fourteenth century when there were over 250 in the city. Although that number has, over the centuries, dramatically decreased, this one has survived.  It was built by the Guinigi, then the most powerful and influential family in the city. The tower represented the prestige of the family and was the largest in the city even when the economic boom of the late fourteenth century meant that towers were springing up all over Lucca.

 

guinigi-tower-2

link

The last descendant of the family gifted the tower to the city, as well as the palace at its base. The roof garden at the top of the tower is, effectively, a walled box filled with earth.

guinigi-tower-3

link

There are seven oak trees there: it is believed that they were first planted in the 14th or 15th century but that over time they have been replanted. However, the ones atop the tower at the moment are still thought to be several hundred years old. [linkmap]

  1. Kalyazin Tower, Russia

kalyazin-1

link

The Kalyazin Bell Tower is a Neoclassical campanile, rising to a height of 74.5 metres (244 ft) over the waters of the Uglich Reservoir on the Volga River opposite the old town of Kalyazin. The steepled belfry was built in 1796–1800 as part of the Monastery of St. Nicholas.

kalyazin-2

link

When Stalin ordered the construction of the Uglich Reservoir in 1939, the old part of Kalyazin, including several medieval structures, was covered by the waters. The structure became the main object of touristic interest in the east of Tver Oblast, and an islet was shored up underneath. It has a small pier for boats. [linkmap]

 

  1. The Leaning Tower of Yekaterinburg, Russia

 

learning-tower-1

link

Yekaterinburg TV Tower is a tall incomplete structure in Yekaterinburg, Russia. Construction works started 1983, but were on-hold at the beginning of the 1990s, as its shaft reached a height of 220 metres (720ft). According to plans, the tower was intended to reach a structural height greater than 400 metres (1,310ft).

There are three parts to the building: the trunk of the tower, the lower joint-work with the base and the metallic aerial. The tower has 26 floors in total (not accounting the floors which make up the base).

learning-tower-2

link

The lifts were never installed. Instead any visitors must clamber up the concrete stairs of the half-complete tower. It is quite the local landmark.

The tower has a slight lean due to engineering mistakes made in its construction. The list does not, however, present any danger and the tower is not due to topple over at any point in the near future. [link1link2map]

5. Ciechanow Tower, Poland

ciechanow-1

The Ciechanow Water Tower was built in 1972 by Jerzy Michal Boguslawsk. There are plans to open a restaurant and observation platform at the top of the tower, but the object is currently out of use. [link]

6. The Pirate Tower, USA

pirate-1

link

A Laguna Beach (California) landmark, this medieval-looking tower is located just north of Victoria Beach. Built in 1926, it was designed as a private spiraling staircase for beach access from above. Today the tower is closed but can still be viewed from the outside at low tide.

To the uninitiated beach goer, the 60 foot (18m) rocket-like structure seems to have been carved out of the cliff by massive waves hundreds of years ago.

Ocean breezes moan through small portals covered by rusting metal grates on the tower’s sides and a large door at the structure’s base, also covered in rust, reveals a wooden spiral staircase twisting to the ledge above. [link1link2map]

7. Sathorn Unique, Thailand

sathorn-1

link

The early 1990s was boom time for the Thai economy. The country was experiencing its most rapid development ever and hundreds of construction projects were started in the capital ofBangkok.

As the wealth of the nation’s people increased it was envisioned that they would demand new, luxury apartments in which to live. The Sathorn Unique is one of them.

The Sathorn Unique was supposed to be another glistening addition to Bangkok’s ever growing skyline, a luxury residential skyscraper of over 600 homes and shops. Yet the building work came to a drastic halt in 1998. The towering building has stood abandoned and incomplete from then on.

sathorn-2

link

Crows circle the pinnacle and rats call its lower levels home. Expat urban spelunkers have explored the building and returned to Khao San Road with stories from its upper reaches. The verdict: it is a dilapidated mess. The future of the Sathorn Unique remains unclear but perhaps someday it will be finished. For now, it looms on the Bangkok skyline with many other abandoned skeletal structures. [link1link2]
9. Shime Tower, Japan

shime-1

link

The winding tower of the former Shime coal mine near the city of Fukuoka, Japan, is unusual even in a country chock full of abandonments. The Shime coal mine tower dates from the middle of World War II: it was built between 1941 and 1943 to help increase the yield of a coal mine established in 1889, and it’s really a wonder the Allies didn’t bomb it to smithereens. Operated by the Imperial Japanese Navy, the mine was rumored to have “employed” Allied POWs so perhaps its survival through VJ Day was just as well. Indeed, the tower and the mine below operated until 1964 when it was finally closed for good.

shime-2

link

The 47.65 meter (156.3 ft) tall tower is of an odd design, having offices and control rooms located above the actual, long gone winding mechanism – huge reels of cable which raised loads of coal from the mine and lowered empty containers and workers back into the depths of the mine up to 430 meters (1,411 ft) below. [link]

10. Montreal Tower, Canada

The tower incorporated into the base of the The Olympic Stadium in the Montreal, called the Montreal Tower, is the tallest inclined tower in the world at 175 metres (574 ft). Its 45-degree angle is awe-inspiring, especially when you consider that the Leaning Tower of Pisa’s tilt is only 5 degrees.

From its summit, visitors can admire the entire Greater Montreal region and up to 80 kilometres (50mi) of the St. Lawrence River valley. A breathtaking panorama, it has been awarded a three-star rating – the highest available – by the renowned Michelin Guide.

A common question from visitors is how can a structure with an incline as dramatic as the Montreal Tower stand? The answer to this riddle lies in mass ratio: the top of the tower has a mass of 8,000 tonnes which is permanently attached to the infrastructure and the solid concrete base buried ten metres below ground level. This base has a mass of 145,000 tonnes, or the equivalent of three aircraft carriers.

Visitors can reach the top of the Montreal Tower on a mesmerizing climb in a glass-encased funicular that holds up to 76 passengers. The funicular is the only one in the world that operates on a curved structure. It has a hydraulic system that allows the cabin to remain horizontal during the two-minute ride to the top. [linkmap]

11. Tower of Wind, Japan

Located just to the southeast of Tokyo’s Haneda airport, in the middle of the ocean, is a rather interesting structure. Referred to as the “Tower of Wind” of “Kaze no to” in local language, it consist of a dazzling white circular base with two blue and white stripped oval shaped structures, that look like two sails from the distance.

This structure is actually a ventilation shaft for the Tokyo Bay Aqualine – an undersea tunnel that lies approximately 40 meters (130ft) below. Tokyo Bay Aqualine is the fourth-longest underwater, 9.6 kilometers (6mi) long that runs from Yokohama to Chiba under the Tokyo Bay.

tower-of-wind-1

The tunnel took 31 years to build, cost 11.2 billion dollars, and shaves some 100km (62mi) off the round the Bay trip. The attractive monolith houses the tunnel’s intake and exhaust ventilation system and also marks the midway point of the undersea tunnel. [linkmap]

12. PL Peace Tower, Japan

Measuring around 600 feet (183m) high, this unusual tower is located at the Church of Perfect Liberty headquarters in Tondabayashi, Osaka, Japan. The tower stands as a monument to all the perished souls of war throughout all time. Within the tower is a shrine in which all known names of the lives claimed in human conflict have been recorded on microfilm and stored in a golden container.

pl-peace-1

link

The structure was originally designed using clay by the church’s late second founder and was built in 1970. The newly developed technique of “shotcrete” was employed in the creation of the tower, formed by spraying concrete on to a wire netting.

Once a year, the Church of Perfect Liberty headquarters is the site of one of the world’s largest fireworks shows. Every July 6th, the members celebrate the passing of their first founder with what they call the “PL Art of Fireworks.” Unlike most fireworks shows, which fire around 5,000 shells, the PL show consists of around 25,000 shells fired. During the finale about 7,000 shells are shot off in unison, lighting nearly the entire sky. [linkmap]
