Girder bridge

The next issue of the series “Architectural constructions. Bridges” is devoted to the girder bridges. Bridges with frameworks, the main load-carrying structures of which are beams or girders, are the most widespread in a modern bridge building. They are used in complex road interchanges. Distinctive feature of the girder system is that only vertical loads are transferred from the bridge superstructures to the piers and horizontal one are absent. Load transfer is carried out by a flexural element of a construction. Bridge structure depends on the size of overlapping of superstructures, the load on the bridge and the intensity of movement.

1. Jubilee Bridge over the River Volga in Yaroslavl 
2. Bridge across the Moscow Canal in the village Khlebnikovo Moscow region

Arched bridges

Arched bridge is a bridge with spans bearing arches as the main load-carrying structures.

The main peculiarities of arched bridges are that their thrust is not only vertical, but also horizontal and arches predominantly work for pressure. Arched bridges are usually constructed for ride at their upper side; their construction is light and they are architecturally bright.

Stamps represent vivid examples of such bridges in Russia:

1. Sartakov bridge across Oka river in Nizhny Novgorod;
2. Bridge across Irtysh river in Khanty-Mansiysk;
3. Viaduct across the valley of Matsesta river in Sochi;
4. Bridge across Don river in Rostov-na-Donu.

Cable-stayed bridge

Cable-stayed bridge - the type of suspension bridge, which consists of one or more of the pylons, connected with the road through a straight wire ropes - rigging. The advantage of these bridges - the relative immobility of the roadway, which makes them suitable as a rail. This is one of the most economical designs of bridges. It is widely distributed in the world. 

  
On the stamps are clear examples of bridges of this type in Russia:

1. Big Obukhovsky bridge in St. Petersburg,
2. Picturesque bridges in Moscow, 
3. The bridge across. Ob (Surgut), 
4. Bridge across. Volga (Kimry).
