St. Petersburg. Bridges over waters... From what they?
St. Petersburg consist of several tens islands. Naturally, bridges are necessary for convenience of inhabitants. Many know that Vasilyevsky, Stone, Krestovsky - islands. And the Petrograd party - the same island, and all Central district (from the Admiralty and further on the South - even for the Moscow station). it is necessary for
A for convenience of residents that all streets proceeded and pro uncountable channels and rivulets, - for what bridges serve.
In the beginning bridges through small rivers and rivulets were wooden. Around there was a lot of tree, it was cheap, and there was not enough stone. For a solution of the problem of a paving of streets and creation of stone embankments even the cunning decree of the tsar was adopted - that everyone who in Piterburkh drives brought with himself a stone. From the pedestrian - one weight, with horse - another, from the cart - the third.
The rivulets of St. Petersburg ceased to spread to the beskrayena on bogs soon, were deepened and sharply lowered in width, and bridges became stone - at first those that on the Nevsky pershpektiva, and then one for one and all others.
In the beginning they were done adjustable not to disturb a passage of the vessels on the navigable rivers. But over time began to do of their stone rather high that boats and small vessels of that time could go under them without problems - and the big ships there and did not wait, too those rivulets were small.
The small rivers flowing within St. Petersburg were put in order, went deep and located to stone coast. Claim that the first Anichkov Bridge - wooden, on piles, - had in length of 200 meters as blocked not only a water stream, but also boggy coast of Fontanka.
Over time efforts of people Fontanka took that appearance what it has today, and the last Anichkov Bridge, stone and wide, decorated with Clodt`s horses, - is much shorter than the wooden ancestor (and is much wider).
When bridges began to do of a stone - even through Fontanka they turned out multiflying. They were done adjustable as Fontanka then was navigable. Such, for example, Lomonosov Bridge. Some Swan Flute allowed creation over it single-span stone bridges under which can slip only unless the boat or the boat. To sailing vessels such bridge completely blocks the road.
All latest ideas in a bridge building were soon used also in St. Petersburg. At the beginning of the 19th century in St. Petersburg the first pig-iron bridges appeared. After all possible alterations through Moika Red, Green and Blue bridges are still thrown “purely pig-iron“. Siny Bridge - the widest in Europe, width makes it 97 meters. It is located at St. Isaac`s Square and it seems not the bridge, and just part of the square, so it is wide. And called so bridges in the flowers in which they are painted for protection from corrosion.
... Yes, absolutely forgot! In St. Petersburg even wooden bridges still remained. For example, bridges of the Peter and Paul Fortress. Ioannovsky Bridge on which it is possible to get to the Peter and Paul Fortress from Kirovsky Avenue. From time to time on it replace flooring boards. Though there almost nobody drives on cars, but in fortress and from fortress always such stream of the people that boards are erased very quickly...
And the second bridge from the Peter and Paul Fortress - that near the Zoo, - too wooden. Why will not be going to remake bridges in concrete or pig-iron in any way or to cover with durable asphalt or concrete? I do not know.
Perhaps, it is tradition? Well, as somewhere - “Porridge, the sir!“?
