In total, 14 superstructure launching stages have been completed during bridge construction
Specialists of Bamtonnelstroy-Most Group of Companies have completed the connection of the superstructures of the new Zeya Bridge in Blagoveshchensk. The final launching stage of the new bridge’s section of the over the riverbed was completed at the eleventh support.
“One of the most important stages of the new Zeya Bridge construction – launching of superstructures – has been completed. The connection was completed at the eleventh support. The next stage involves installation (lowering) of the superstructures onto bearings and construction of a roadway slab with expansion joints. These works are already underway on the left bank, and we will get to the same works on the right in the near future,” Project Manager and Chief of Zeya Branch Office of Bamtonnelstroy-Most JSC Eduard Davydov said.
The first metal structures of the superstructure arrived at the construction site in December 2020, and in April 2021, the builders carried out the first stage of the superstructure launching. During the construction of the new Zeya Bridge, the builders applied the longitudinal launching method by using hydraulic equipment. The installation of superstructures was carried out from both banks, so they could meet each other. 14 stages of the launching were carried out in a year and a half: 8 stages from the left bank and 6 stages from the right bank. Now the superstructure with a total weight of 8,500 tons and a length of 1,750 meters is installed onto 20 supports (6-26).
“Today a landmark event has taken place – the builders have connected a new bridge. It is being built on the instructions of the President, 23 billion rubles have been allocated for the project in total. In a year we will put the new bridge into operation,” Vasily Orlov commented. “Bamtonnelstroy-Most, the contractor, is very professional and strong, the specialists of this company have built the bridge to China and the new bridge across the Zeya River is being constructed using the similar technology. The work is carried out ahead of schedule, despite the fact that there have been some difficulties due to the coronavirus pandemic, a very strong flood last year, and the imposed sanctions. Once again, the company has proven itself as a reliable partner,” Governor of the Amur Region Vasily Orlov said.
The total length of the bridge crossing is 10,285 meters, of which the bridge takes 1,933 meters, and the access roads take 8,352 meters.
The bridge crossing rests on 26 supports.
Car traffic on the bridge will be arranged in one lane in each direction. According to preliminary estimates, the implementation of the project will decrease the traffic load on the existing bridge by 40-60%, which will allow the residents of the Amur Region to cover the distance between the city and the federal highway more conveniently.
