Top 10 Amazing bridges in world

The world’s most famous bridges may not be the longest bridges, tallest bridges or highest bridges, but they are the most recognizable bridges in the world by far.You can now  take a tour through the ancient spans, iconic structures and bridges with unique and interesting features.

Here are the top 10 most famous bridges:

1. Tower Bridge,London, England.

Tower Bridge (built 1886–1894) is a combined bascule and suspension bridge in London which crosses the River Thames. It is close to the Tower of London, from which it takes its name, and has become an iconic symbol of London.
The bridge consists of two towers tied together at the upper level by means of two horizontal walkways, designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers. The bascule pivots and operating machinery are housed in the base of each tower. The bridge's present colour scheme dates from 1977, when it was painted red, white and blue for Queen Elizabeth II's silver jubilee. Originally it was painted a mid greenish-blue colour.

2. Golden Gate Bridge,San Francisco

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. The structure links the U.S. city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers. 

The Frommers travel guide considers the Golden Gate Bridge "possibly the most beautiful, certainly the most photographed, bridge in the world".

3. Brooklyn Bridge,New York City

The Brooklyn Bridge looms majestically over New York City's East River, linking the two boroughs of Manhattan and Brooklyn. Since 1883, its granite towers and steel cables have offered a safe and scenic passage to millions of commuters and tourists, trains and bicycles, pushcarts and cars. The bridge's construction took 14 years, involved 600 workers and cost $15 million (more than $320 million in today's dollars). At least two dozen people died in the process, including its original designer. Now more than 125 years old, this iconic feature of the New York City skyline still carries roughly 150,000 vehicles and pedestrians every day.

4.The Wind & Rain bridge,China

Chengyang Wind and Rain Bridge, also called Yongji Bridge or Panlong Bridge, spans the Linxi River of Sanjiang County. Built in 1916, it is 64.4 meters (73.43 yards) long, 3.4 metes (3.72 yards) wide and 10.6 meters (34.78 feet) high. Constructed with wood and stones, its surface is paved with wooden boards and both sides are inlayed with railings. On the bridge itself, there are five tower-like kiosks with 'horns' and eaves which resemble the flapping wings of birds.

To one's surprise, the builders of this bridge did not use any nails or rivets. Instead, talented Dong people dove-tailed many pieces of wood. Though several decades old, it is still very sturdy. In a word, it is grand and looks like a brilliant rainbow crossing over the river.
Walking out onto the bridge, you can sit on the bench and appreciate the picturesque scenery. Looking far ahead, you will be intoxicated with what you see: the Linxi River meandering from the horizon; tea trees growing on the hills; local peasants working hard in the fields; and waterwheels turning, sending water cascading down the river.

5.Ponte Vecchio,Florence,Italy

The Ponte Vecchio (Old Bridge) is a medieval bridge spanning the river Arno in Florence. It is one of the few remaining bridges with houses built upon. The Vasari corridor that runs over the houses connects the Uffizi with the Pitti Palaceon the other side of the river.

The pedestrian bridge is often teeming with tourists and the many musicians, portraitists and other entertainers create a constantly vibrant atmosphere. The bridge is at its most beautiful at dusk, especially when seen from the Ponte Santa Trinità.

The Ponte Vecchio is the oldest bridge in Florence. It is believed that a bridge already existed here during the Roman times. Its current appearance dates back to 1345 when it was built to replace a bridge which was destroyed by a flood. Houses were built on the bridge, a common practice in large European cities during the Middle Ages.

The Ponte Vecchio was the only bridge in Florence that survived the Second World War unscathed.

6. Covered Bridges ("The Kissing Bridge"),Ontario, Canada

The West Montrose covered bridge is recognized as a historic site by Ontario's Archeological & Historic Sites Board. It is Ontario's last remaining covered bridge and has a 198' span across the Grand River. Visitors come from all over the world to see and photograph this picturesque bridge.

The roof over the bridge served to protect the large timbers and trusses from the elements, and this is also the reason the bridge is still standing after more than 100 years. Uncovered wooden bridges have a life span of only 10 to 15 years because exposure to rain causes unprotected joints to rot in summer and freeze in the winter; the hot sun causes the wooden planks to dry and curl. Applying oil and tar to preserve the floor made the surface slippery when wet. 

Horses fear rushing water and would often become spooked as they approached bridges. A horse will trot up to the opening of a covered bridge and clip-clop through, reassured by the side walls and the light at the end of the tunnel.

The bridge was built in 1881 and underwent major repairs in 1999. Light traffic is still crossing the bridge daily including horse and buggies. 

The bridge is often referred to as "The Kissing Bridge" because it is enclosed and the soft light provides a feeling of intimacy for the romantic.

7. Glenfinnan Viaduct, Glenfinnan, Scotland
Top 10 bridges around the world
Fans of the Harry Potter films will recognize this as the railway viaduct that the Hogwarts Express chugs across. It's not the only film to feature it. It 'starred' in Charlotte Gray, Monarch of the Glen, Stone of Destiny and Ring of Bright Water too. 

Built by Sir Robert McAlpine at the end of the 19th century, the viaduct is composed of 21 arches, each spanning 15 metres and has a maximum height of 30 metres offering sumptuous views down to Loch Shiel below. The railway viaduct is on the West Highland Line in Glenfinnan, Lochaber in the Highlands and a round-trip ticket, between mid-May and the end of October, will set you back 32 pounds (around $50).
8. Si-o-se Pol, Isfahan, Iran
Top 10 bridges around the world

Si-o-se Pol, which means the Bridge of 33 Arches, has stood in Isfahan, Iran, since the 17th century. Spanning the river Zayandeh Rud, it's one of 11 bridges in Isfahan. It's one of the most famous examples of Safavid bridge design although Khadjou Bridge is considered to be more beautiful. 

There are two rows of 33 arches and its yellow brick and limestone masonry give it that buttery softness that, when the sun hits, makes it appear to melt into the river. It's a charming bridge of alcoves, where you can sit and admire the view. Or, in the tea house, sip cups of steaming tea.
9. Teufelsbrucke, Switzerland

Top 10 bridges around the world

This is the bridge that was built by the devil. Or so it is said. The story goes that the devil built the bridge and in exchange for his engineering and construction skills, he'd receive the first soul to cross it. The canny villagers sent a goat instead of a person, and, enraged by this, the devil tried to destroy his newly constructed bridge by throwing a boulder (the Teufelsstein, the devil's stone) at it. 

However, catching sight of an old woman carrying a cross, he took fright and ran away, dropping the stone as he went. Myths aside, the Teufelsbrucke spans the Reuss River high up in the Swiss mountains in the canton of Uri. It provides access to the St. Gotthard Pass. The bridge that is in use now is actually the third bridge. The first bridge (wooden and built by the devil) was built in 1230 and the second (built in the 1820s) is located close to this 'new' (1950s) concrete bridge.

10.Pont Alexandre III, Paris, France

Pont Neuf is Paris's oldest bridge - and one of its most famous - but the Pont Alexandre III is the most extravagant and highly decorated bridge on the Seine. This arch bridge (connecting the Champs-Elysees quarter with the Invalides and Eiffel Tower quarters) was built for the Universal Exposition of 1900, the great world's fair. 

Russia's Tsar Nicholas II lay the first brick (it was at a time when France was courting Russia as an ally) and it was named after the Tsar's father Alexander III. This historic monument is studded with gilded-bronze winged horses, compositions in copper that represent the nymphs of the Seine (the nymphs of the Neva in Saint Petersburg are represented downstream) and ornate lamp posts (candelabras really) that are adorned with cherubs.

Computer Mouse Tips To Know

While the mouse may seem like a trivial aspect of your computer, there are probably a lot of things you don't know about its use. 

Here are some great tips on how to maximize your use of the mouse, which will increase your overall productivity on the computer.

1. Shift Key and Mouse Click

In text editing programs like Microsoft Word and even on your regular webpage, you can highlight all or portion of a certain text using the Shift key and clicking on your mouse. Place the cursor (the sign of the mouse) at the beginning of a paragraph and hold down the Shift key. Click at the end of the paragraph to highlight the entire thing, or wherever in the text that you would like to end the selection.

Another tip: Holding down the Alt key while highlighting text in a text editor will allow you to selectively highlight the text. This is most useful if a paragraph or other text is in a column.

2. Use the Scroll Wheel to The Max

Most computer mice have a scroll wheel in between the right and left click buttons that allows you to scroll up and down the page by moving the wheel. However, this wheel can be used to do much more than just scroll!

- The mouse wheel can be used as a button. Pressing down on the wheel is like clicking with a third mouse button. You can press down on a link to open the web page in a new tab in your browser. It can also be used to close a tab in the browser by clicking the wheel on an already open tab.

- Hold down the Shift key as your scroll up and down in your Internet browser to quickly move back and forward between webpages. Scrolling up goes forward while scrolling down goes back.

- To zoom in and out on a web page or document, hold down on theControl (Ctrl) key and scroll up to zoom in, scroll down to zoom out.

- Some mouse wheels can be pushed left or right to move backwards (left) and forwards (right) on a webpage.

3. Select With Double or Triple Clicks

Words can be selected by double clicking the word. If you want to highlight an entire paragraph, click the mouse button three times on the text

4. Right-Click

You can use the right-click when you want to highlight text or wish to view the properties of an object. For example, if you highlight text, you can right-click on the highlighted item and copy it, then right-click anywhere else to paste it.

Another tip: If you right-click text and drag it while continuing to hold the right mouse button, when you let go you will be given the option to move or copy the text. This will save you the extra step of having to right-click again where you want to paste the text.

5. Ctrl Key and Mouse Click

When you hold down the Ctrl key, you can left-click to select multiple files or highlight multiple sections of text. You can also hold down the Ctrl key and use the down or up arrows to select the text.

6. Use Mouse Side Buttons

Newer computer mice have side buttons on the side of the mouse (next to the usually right and left keys). 

Image result for mouse side buttons
These buttons can be programmed to do most anything, but by default, the left-thumb button can be used to go back on a web page, and the right button to go forward.

7. Use Snap to Feature

Windows has a handy 'Snap To' feature that will automatically move your mouse to buttons in the dialog box, such as the 'X' to exit or the '_' to minimize. For example, to close a window, you may get a prompt asking if you really want to perform the task. With the Snap To feature, the mouse will automatically move to the OK button so that all you have to do is click if you agree. To enable this feature, open the Mouse properties under the Control Panel, and check 'Snap To' under the Pointer Options tab.

8. Manage an Open Window

Double-click on the top title bar of a window to maximize the window or, if it is already maximized, to resize it. Double click on the icon for the window in the top left corner to close that window.

9. Move the Mouse With Your Keyboard

Instead of using a regular mouse, you can enable your computer to use the number pad instead. This trick takes some time to master, but it can make your use of the computer much more efficient.

10. Select with double and triple click 

This is the most used tip but for the completeness of  this post  i have mentioned it. You can select a word by double clicking it. And if you want to highlight the whole paragraph then click the mouse button three times on any paragraph.

11. Hold Your Mouse Correctly!

There is no need to hold onto your mouse for dear life! The mouse will move well with just a light touch, which will also protect the health of your wrist. This is important for those that use the computer for hours a day, because incorrect posture on the mouse, or keyboard for that matter can cause a lot of unnecessary pain.

Customize your mouse

Finally, if you have a mouse with more than two buttons, installing the included mouse software allows you to customize the mouse even more. 

For example, if you don't use the side buttons to move back and forth in a web page, change it to something you do more often, such as switching between open windows or opening the calculator.
