They are structures that connect one part of a place to another for people and vehicles to get across an obstacle or long distances easily and in a shorter time. The design will vary depending of its use and its materials. Usually bridges are made of wood, concrete, steel, bricks, stone, etc. **__ Types of bridges: __**

__ The beam bridge: __ It is the earliest and simplest king of bridge; it is made of a simples beam supported at the end of both sides but unsupported in the middle. Most simple beam bridges are made of wood laid on stones supports. Lately these bridges have been made from steel or concrete, depending on how long it has to be and the weight it is going to support.

__ The arch bridge: __ These bridges are formed by a semicircle shape. They where originally built of stone or brick. This kind of bridge dissipates the weight from the center of the deck to the abutments.

__ The suspension bridge: __ A suspension bridge is one where cables are strung across the obstacle and the deck is suspended from these cables. Modern suspension bridges have two tall towers through which the cables are strung. For suspension bridges steel cables are commonly used.

The importance of a bridge in a town, city, etc., is that it communicates to different places and make possible for people to go to one place to another and interact with different cultures, get stuff that they won’t find on their own homeplaces, etc. The construction involves precision, hours of work and physics knowledge.

<span style="color: #555555; font-family: "Lucida Sans Unicode","Lucida Grande",sans-serif; font-size: 150%;">The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal, and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world. <span style="color: #555555; font-family: "Lucida Sans Unicode","Lucida Grande",sans-serif; font-size: 150%;">The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe. Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. <span style="color: #555555; font-family: "Lucida Sans Unicode","Lucida Grande",sans-serif; font-size: 150%;">Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003.
