Thirty of 33 piers of the unique bridge across the Eastern Boshporus Strait, including the two largest bridge piers – М1 (Nazimov Peninsula) and М12 (Russky Island) – have been brought to design elevation.
According to Alexey Baranov, Director of USK MOST’s Vladivostok branch, the two bridge piers (M1 and M12) will function as a cross-over span and take horizontal loads from the elevated road superstructure and the cable-stayed bridge’s stiffening beam.

Each pier contains approx. 8000 m3 of high-grade concrete. Each of the flat-topped bridge piers is 35 m high. Each pier column is 8.9х18.5 m. They house channels for engineering networks and rooms for equipment to monitor the condition of the bridge crossing structures after the bridge is commissioned.
Progress on the other project jobsites is going as scheduled. Pour No. 5 of the overhead road slab (trestle span EN15-EN16) on the Nazimov Peninsula has been concreted. This required 157 m3 of concrete. Pour length is 24.7 m, width is 25.4 m, and thickness is 25 cm.
Construction of 320 m bridge towers is underway on either side of the Eastern Bosphorus. It should be noted that construction of pours Nos. 12-14 is one of the most challenging phases of construction of the giant bridge towers; at this phase, their pier columns will be coupled by a lower link beam, which will function as a rest for the bridge stiffening beam.

Fixing the 600 t structure in this part of the bridge tower requires doubled reinforcement and installation of embedded parts with sophisticated anchorage via conventional flexible rests and Dywidag stressed reinforcing bars and high-strength cables. The extremely complicated reinforcement and the need to construct three diaphragm plates in each pier column within 12-14 pours substantially increases working time. However, sophisticated technical support for all processes and competent engineering staff ensure top-quality solutions to the most complicated tasks.
At present, the bridge builders have completed concreting Pour No. 14 of the pier column of the giant М6 tower on the Nazimov Peninsula. The operation was conducted non-stop over 17 hours. Pour reinforcement consumed 24 t of main reinforcement, and 183 m3 of concrete were poured. The right-hand pier column of tower M6 is 67.9 m asl. Current operations include preparation for concreting Pour No. 12 of the left-hand pier column of bridge tower М7 on Russky Island.
