Russia's longest bridge Crimean Bridge
Source: Russia Today
Crimean Bridge, also known as Kerch Strait Bridge or Kerch Bridge, is a pair of parallel "Twin" bridges, one is a highway bridge and the other is a railway bridge, spanning Kerch Strait , connecting the Taman Peninsula of in the Russian mainland Kerch Strait and connecting the Taman Peninsula of in the Kerch Strait region of Kerch Peninsula of in the Kerch Strait region of Kerch Peninsula of Crimea . The total length of the
bridge is 19 kilometers, of which the sea span is 7.5 kilometers long, and the clearance under the main span bridge is 33-35 meters. It is the longest bridge built in Russia in history and the longest bridge in Europe. The bridge project costs a total of 227 billion rubles (approximately 25.5 billion yuan), and is known as Russia's "Century Project".
In February 2016, construction of highway bridges and railway bridges started at the same time. The highway bridge was opened to traffic on May 16, 2018. The railway bridge passenger train was opened to traffic on December 23, 2019. Freight trains will be opened on June 30, 2020. After the opening of the bridge, the traffic volume of cars quickly exceeded the Kerch Strait ferry, and the peak season of summer tourism is the peak traffic of the Crimea Bridge. On August 15, 2020, a traffic volume of 36,393 vehicles was created in a single day. More than 7,000 piles were used on the
bridge, which were driven 91 meters below the water surface. Some of the piles are inclined to make the structure more stable during earthquakes.
The geological conditions of the Kerch Strait are harsh, and there is a tectonic fault, and the bedrock is covered with a 60-meter-high silt layer. In addition, about 70 mud volcanoes were also discovered. Considering the structure of the strait and the ocean current conditions, some experts expressed doubts about the safety of the project.
Invented a new type of bridge damage early warning sensor in the UK
Source: Engineering and technology
UK, Queen's University Belfast (QUB, Queen's University Belfast) Researchers have developed a new sensor that can detect changes in riverbeds and warn them before bridges are damaged, making bridge operations safer and help prevent bridge collapse accidents in extreme climates.
The erosion and erosion caused by changes in the riverbed usually do not leave obvious signs of damage to the structure, and therefore is also one of the main reasons for the collapse of major bridge structures around the world. The safety hazards of bridges caused by the erosion have reduced the number of travelers in the UK by an average of 8.2 million per year, causing economic losses of £60 million.
At present, testing of the initial model of the sensor has been completed. In the near future, the sensor will be applied on a bridge in Northern Ireland to ensure the safety of aging bridges. The Sensor Research Project is funded by Impact Acceleration Accounts of UK Research and Innovation, with Invest NI responsible for market development funding.

Norway The longest bridge built using BIM technology is about to be opened to traffic
Source: Fast Company, Architect News
Norway, near the city of Honeyfoss, about 31 miles northwest of Oslo , the Randselva Highway Bridge is under construction, with a total length of about 634 meters and the highest point is about 33 meters above the ground. The bridge spans a variety of terrain and buildings, including rivers, valleys, foothills and existing railway lines. It will be the longest bridge ever built with BIM technology without using two-dimensional floor plan. It is expected to open to traffic in July. The project manager of
said that compared with the traditional method, the use of BIM can accurately control and adjust every detail of bridge construction, reducing the expensive cost of drawing modifications and additional materials during construction, and saving about 10% of the cost. Especially in multinational projects, BIM standardization makes collaboration easier. The gradual replacement of 2D drawings is a major change in the construction industry, and the application of BIM models will also promote the large-scale automated construction of future construction projects.
Georgian Diamond Bridge will win the Guinness World Record

Georgian , Tsalka Canyon, west of the capital Tbilisi, a newly built diamond-shaped glass suspension bridge is open, with a total length of 240 meters, and the highest point is 280 meters from the bottom of the canyon, with a construction period of 3 years. Designed by Kass Group, the Diamond Bridge is inspired by the natural form of the canyon.
The suspended diamond structure in the center of the glass suspension bridge is currently the largest and highest free suspension structure in the world. It is currently applying for Guinness World Record .
diamond structure is used as a multi-functional leisure area. Visitors can enjoy the beautiful scenery of the canyon while enjoying the drinks, and can also experience the high-altitude zipline bicycle project to cross the canyon.
will also build ecological channels, visitor centers, hotels, swimming pools and other structures for hosting large events, which are expected to cost nearly NZ$65 million (120 million Georgian Laris).
