The closing paired steel stiffening girder panel of the bridge to the Russky Island has been lifted from the Eastern Bosphorus Strait water to the 70-meter design elevation. It will take to span 36 meters more in order to close the world record breaker 1104-meter long channel span.
“In spite of a highly challenging conditions in the Eastern Bosphorus Strait, the lifting of paired panel number 49-50 on the Russky Island side has been completed normally,” commented Aleksandr Kishkin, SK MOST Rotation Shift Manager.” “A storm advisory was issued in Vladivostok on March 18th because of a strong wind. It is extremely dangerous for small-size vessels to navigate under storm conditions, which is why motor boats and ferry boats were prohibited from going to sea in any direction. However the strong wind subsided by Sunday evening and sea roughness calmed down. As soon as the decision was made to revoke the storm advisory, we have proceeded with the lifting of the 350-ton structure. Generally speaking, this is a normal thing in building the unique project under Primorie weather conditions where we have to squeeze into “windows” all the time to conduct installation. High expertise of our professionals and workforce and the teamwork interaction in the construction water area made an important contribution as well. The paired closing panel was lifted in the dark time; installation was started at about ten o’clock in the evening and has been completed by midnight.”
“After panel 49-50 has been lifted from the water on the Russky Island side, we have completed installation of paired sections of the channel span deck from the water,” added Aleksey Baranov, Director of the OJSC USK MOST Branch in Vladivostok. “The total length of the opposed cantilever sections of the main steel stiffening girder is now 1068 meters or 96.7% of the total length. To carry on the channel span closing process, we will have to install three final single panels, one on each side of the eastern Bosphorus Strait and the central closing panel, which will finally link Vladivostok to the Russky Island.
