Rialto Bridge Presentation

Hi my name is Irene Rodriguez and this is my bridge presentation about Rialto Bridge **Introduction** A bridge is a structure that has as main purpose to provide a passage over an obstacle, be it rivers, chasm, road, or the like. Bridges have been used by humans since ancient times, whether it was built naturally by rocks or falling trees, or built by men.

**Types of Bridges** There are many types of bridges: · Beam Bridge: are the most simple of structure, they are strong and they are commonly used as viaducts. Uses of Bridges: Bridges have mane uses, among them are, to connect places, to facilitate communications so that supplies can arrive faster, and enhance economics.
 * Arch Bridge: works by transferring the weight of the bridge, they are very strong and lasting.
 * Cable-Stayed Bridge: consists of one or more columns or towers, with cables supporting the road, this cable go from the road, directly to the bridge tower, making them less flexible, stronger, and safe for train to pass through.
 * Covered Bridge: mainly made from wood, this bridges have walls and roof, making them look like a tunnel.
 * Cantilever Bridge: It' a bridge built using beams that are only anchored at one end. These bridges are mostly made of steel beams.
 * Suspension Bridge: is the type of bridge where the road is held by cables that are suspended by suspender cables that go between the towers. This type of bridge is very flexible, so it is not used for trains because it could be dangerous.
 * Truss Bridge: usually made of steel beams, creating a structure of triangles. These bridges are strong and simple.

**Rialto Bridge** It’s located over the Grand Canal in Venice, Italy, and it’s probably the most visited and most photographed bridge in this city, it has become a landmark and venetians are proud of it. This bridge is one of the four bridges spanning the Grand Canal, and it is the oldest bridge across the canal. The present bridge was designed by Antonio da Ponte, its construction began in 1588 and was completed in 1591, and it was used to replace a wooden bridge that collapsed in 1524. The Rialto Bridge has a width of 22.90 meters and height of 7.32 meters. It is made of stone and it’s a arch covered bridge type and its for pedestrian use only.

The Rialto Bridge is formed by two inclined ramps covered by a portico with shops on either side; this area has a market place for Venetians, and it was design so galley ships could pass under it, that’s why its arch is higher than usual, and it has become an Architectural Icon of Venice.
