JSC Stroytransgaz began the second stage of pushing of spans of the Frunzensky Bridge over the Samara River. As of now, the first of 12 sections featuring a length of 88.5 meters has been already pushed into the span. During the second stage, the assembly of the first and the second sections will be pushed 41 meters more into the riverbed. Therefore, upon the completion of works associated with pushing of the deck, said part featuring a total length of 196.5 meters will reach its design location between Piers 2 and 4.

The main difference between the second section and the first section is the availability of pillars featuring trusses in a form of metal V-columns featuring a height of 20 meters. Konstantin Agalakov, Head of the Project Construction Management Group of JSC Stroytransgaz, said the following on this unique feature: “We’re going to use a truss system during the construction. The trusses act as auxiliary constructions that increase stiffness of longitudinal beams of the bridge deck. The truss system will allow for a significant increase of the bridge structure service life.”

The pre-assembly of the spans from metal blocks is performed on the left bank of the Samara River on a designated assembly rig. As the sections are completed, they are pushed one by one over the riverbed along the guides by powerful jacks. In total, the builders will have to construct the central section of the deck featuring a length of 596.5 meters (between Piers 2 and 7), as well as two side sections. As of now, 2,230 tonnes of metal of the target amount of 9,000 tonnes to be used for the deck of the Frunzensky Bridge have been constructed.

Parallel to the assembly of the deck, works are being performed in the Samara riverbed. Yesterday, the builders completed works at Piers 5 and 6 of the bridge over the Samara River, while the construction of the remaining Piers 3 and 4 located in the Novaya Gavan bay is still in progress.

The works associated with the junction ramps to Shosseynaya Street on the left bank of the Samara River are in progress. Following the prismatic piles sinking, the builders began the installation of the grillage (a monolithic reinforced concrete slab) of Pier 1 of the crossover at Ramp C-3 over the main way road. The works at the bridge over the boggy Bannoye Lake are in progress as well and include the building and strengthening of the embankment cone near the bank piers.

Alexander Nefyodov, the First Vice-Governor and the Chairman of the Government of the Samara Region, noted during the visiting meeting to the site: “The Frunzensky Bridge is one of the most important objects for the Region as a whole, as well as for Samara. The need for the construction of a bridge here was long overdue. Construction of the bridge is currently in line with schedule. The estimated volume of assembly works planned for this year must be completed before the winter.”

Project Info

The Contract for Frunzensky Bridge construction was signed in October 2015. On November 20, an official ceremony took place to celebrate the start of Frunzensky Bridge construction. The construction Project includes erection of the six-lane composite girder bridge over the

Samara River (667m long with a 22m wide carriageway), reinforced concrete bridge over the boggy Bannoye Lake (79.6m long), construction of two interchanges at Shosseynaya Street and Frunze Street, five retaining walls made of cast in-situ reinforced concrete, and an over 70m long overpass located at the ramp over the main route motorway. The new motorway will be 2.67 km long.
