300 Days From the Start of Construction of Frunzensky Bridge in Samara

See photo gallery

It has now been 300 days since the construction of the Frunzensky Bridge officially started in Samara. Governor of Samara Region N. I. Merkushin has repeatedly listed the Frunzensky Bridge among the key infrastructure sites of the Samara Region. “Given the construction of new Yuzhny Gorod urban district, Preobrazhenka industrial park and Sanorsa, the Frunzensky Bridge is vital for us,” he said.

By now, a large-scale construction, on which PJSC Stroytransgaz acts as the general contractor, has been deployed on the both banks of the Samara River. Three of the eight bridge piers have been erected, whilst the rest are being constructed. All of them are in different states of readiness. The construction of the superstructure on the Bannoye Lake Bridge is almost complete.

Still in progress are the construction of two interchanges on Frunze St and Shosseynaya St, as well as the filling of an embankment for the main section of the motorway on the left bank of the Samara River. The construction progress follows the schedule.

The below is the latest photo report on the facility construction progress.

Left Bank
Bannoye Lake Bridge

The final phase of the superstructure construction on the Bannoye Lake Bridge has started: installation work is over 70% complete.

1,600 cubic metres of concrete are required to construct the superstructure of the Bannoye Lake Bridge.

Special-purpose auxiliary structures and facilities have been dismantled in the areas of piers 7, 6 and 5. Here, the concrete gained the required strength.

All of the construction phases require high project performance accuracy which is ensured by geotechnical surveying.

Samara River Bridge

On the left bank, two bridge piers (piers 7 and 8) are entirely complete.

In between the Samara River Bridge and the Bannoye Lake Bridge, sand is deposited using the hydraulic fill method to form an embankment for the main section of the motorway.

The embankment is 10m high. And it is almost as high as the piers.

Bored cast-in-situ piles are now installed in the area of pier 6 which is located in the riverbed. Currently, water is pumped from the enclosed sheet piling area. Containment booms have been installed on the site. They serve to protect the riverbed against pollution.

Sheet piling at pier 5, which is technologically needed to construct the pier itself, is complete.

Over 5,000 mᶾ of soil were extracted from the enclosed sheet piling area using a grab (special-purpose equipment). By now, a packing concrete layer has been installed to construct raft foundation for the pier. This layer is an extra concrete layer that is installed on the bottom of a pit in case of a large water inflow and operates as a water proofing.

Over 500 mᶾ of concrete were cast to construct the packing concrete layer at pier 5.

At pier 4, operations are envisaged to lift and dispose of the barge.

Interchange at Shosseynaya St

Filling of working platforms at all of the ramps is underway in the area of the envisaged interchange at Shosseynaya St. There will be eight ramps in total (С-1 through C-8). Pile drains are being installed at ramps С-3 and C-7.

Right Bank
Samara River Bridge

The right bank will host three bridge piers. All of them are in different states of readiness.

At pier 1, the raft is complete, concrete is being cured, and the construction of the pier body is to start soon.

Onshore pier 2 is entirely complete.

At pier 3 area, work to erect crane bridge has started.

Interchange at Frunze St

An interchange giving access to the key streets of the city—Frunze, Kuybysheva, Chapayevskaya, and Krupskoy—will be constructed on the right bank of the Samara River. The future interchange will allow for easier traffic flows heading to the old part of the city and total 10 ramps.

The construction of the ninth ramp is underway. The ramp will pass along the bank of the Samara River and lead to Molodogvardeyskaya and Krupskoy streets. RC retaining walls, which have a supporting function, are now being constructed to support soil on steep slopes.

The Frunzensky Bridge is being constructed on a 24/7 basis. Currently, over 200 workers and 70 machinery units are engaged in the construction work.

Background

The contract for the construction of the Frunzensky Bridge was signed in October 2015. On 20 November, an official ceremony took place to celebrate the start of the construction of the Frunzensky Bridge. The ceremony was attended by Nikolai Merkushkin, Governor of the Samara Region, Mikhail Babich, Plenipotentiary Representative of the President of the Russian Federation in the Volga Federal District, Maxim Sokolov, Minister of Transport of the Russian Federation, and Mikhail Khryapov, General Director of PJSC Stroytransgaz. The Frunzensky Bridge Project envisages the construction of a six-lane composite-girder bridge across the Samara River (667 m long, with a 22m wide carriageway), a reinforced concrete bridge (79.6 m long) across the boggy Bannoye Lake, and two interchanges at Shosseynaya and Frunze streets. The new motorway will be 2.67 km long.
