The first cable-stayed bridge of St. Petersburg - Bolshoy Obuhovsky bridge

One of the amazing cities, famous for their majestic bridges, is St. Petersburg. There are more than 800 bridges, which have their own special design and materials used for manufacturing. They are built in different eras. One of the amazing structures is the first cable-stayed bridge of St. Petersburg - Bolshoy Obukhovsky Bridge. It is a suspension bridge, which consists of a number of pylons connected to the road surface by means of steel cables. It is the first non-water bridge across the Neva River, along which it is always possible to get to the opposite shore in case all other bridges are divorced.

The St. Petersburg cable-stayed bridge is one of the parts of the ring road. It is located in the middle reaches of the Neva, on the border of the Vsevolozhsk District and Nevsky District of St. Petersburg. With its help, the Obukhov side avenue and Oktyabrskaya embankment are connected. For a long time could not decide on the name of the bridge. The final decision was to name it in honor of the adjacent area, but since in St. Petersburg a bridge with this name already exists, the "Big" prefix had to be added to the new bridge.

Its construction began in 2001. On piles with a diameter of up to 1.7 meters monolithic reinforced concrete supports were installed . The width of each span structure, made of two longitudinal beams, is 25 meters, and a height of 2.5 meters. The length of the bridge along with the exits to the highway reaches 2884 meters, and overflights over the water have a height of up to 30 meters, which provides easy access to all vessels. As for the height of the spaced pylons, of which the St. Petersburg cable-stayed bridge consists, it is 123 meters. The carriageway is made in the form of an orthotropic plate, which is two steel plates, reinforced with longitudinal stringer (ribs).

The bridge is one of the longest in Russia. If you look at the bridge from a height, you can see two identical bridges located next to each other and having the opposite movement. Despite the fact that according to the plan, the completion of the construction of the first half was due in late 2003, the grand opening of the first part of the bridge took place on December 15, 2004. After three years, on October 19, 2007, the second part of the cable-stayed bridge was also ceremonially opened.

Thus, the cable bridge of St. Petersburg has an eight-lane movement, four strips on each part. The estimated throughput now here is 80,000 cars per day.

All cable-stayed bridges have one advantage - it is the immovability of the canvas. In the world, these bridges are used as railroads. Throughout the world, such bridges have been built since the 1950s. Today, the cable-stayed bridge of St. Petersburg is not just a convenient functional transport facility. It also serves as an adornment of the city, admired not only by local residents, but also by the guests of the northern capital.

In the period of construction of the bridge, before the opening of the first line, the Museum of cable-stayed bridge was organized. This is a unique museum of its kind, which is the first and only museum in the whole of St. Petersburg dedicated to a specific building site. Here you can see the history of construction, with details, designs and plans for the future, the prospects of quantum bridges.
