M-11 Neva Express Motorway M-11 Neva Express Motorway


The M-11 Neva toll expressway between Moscow and St. Petersburg is one of the largest infrastructure projects in Russia. It is a much-needed congestion reliever of the M-10 motorway. The new road bypasses all populated areas in Moscow, Tver, Novgorod and Leningrad Regions.

Construction of the expressway allowed decreasing the traffic and reducing accident rate on the M-10. Travel from Moscow to St. Petersburg takes now 6-7 hours.

Stroyproekt developed the design and detail design of several M-11 sections, as well as the design of large and non-standard bridges, overpasses and flyovers for the whole road. Our company also performed construction supervision for Stages IV and V.


М-4 Don Motorway М-4 Don Motorway


The M-4 Don runs through Voronezh, Rostov-on-Don and Krasnodar and connects the central and northern regions of the European part of the country with the Northern Caucasus, the Black Sea coast, and the port of Novorossiysk. The road is part of the international North-South transport corridor.

Our company developed the design and detailed design for reconstruction of several road sections, including settlements bypasses.

Reconstruction of the motorway will improve the traffic and environmental situation, reduce travel time and ensure driving comfort for all road users.


Western High Speed Diameter (WHSD) Western High Speed Diameter (WHSD)


WHSD is the first urban toll expressway in St. Petersburg, 46.6 km in length, which comprises a great number of complex engineering structures. The road links the southern and western city districts with the Ring Road, Vasilievsky Island in the center and the Scandinavia highway in the north, and has improved accessibility of the main transport hubs — Pulkovo Airport, the port of St. Petersburg and the Marine Façade passenger terminal. The new expressway has reduced travel times in some city areas by 50-70%.

WHSD features the second and the third longest bridge structures in Russia — Southern mainline flyover with the bridges over the Sea Channel and Korabelny Fairway, 9378 m long, and Northern mainline flyover with the bridges over Petrovsky Fairway and Elagin Fairway, 8794 m long.

Ob River Crossing – Bugrinsky Bridge in Novosibirsk Ob River Crossing – Bugrinsky Bridge in Novosibirsk


Bugrinsky Bridge is the third bridge across the Russia’s largest river Ob in Novosibirsk. The bridge is part of South-West transit highway, which links the M-51 Baikal and M-52 Chuisky Trakt motorways.

The network arch of the bridge resembles the city’s coat of arms, which features an arch bridge and a red bow.

An unconventional launching procedure on a vertical circular curve was chosen for erection of the arch, which required minimum of auxiliary steel structures and enabled the shortest construction time.

In 2016, the project received a FIDIC Award of Merit for demonstrating innovation, quality, professional excellence, principles of transparency and integrity, sustainability and respect for the environment.

Voroshilovsky Bridge across the Don River Voroshilovsky Bridge across the Don River

Reconstruction of the Don crossing including a non-standard bridge aligned with Voroshilovsky Prospect in Rostov-on-Don.

Blagoveschensky Bridge Rehabilitation Blagoveschensky Bridge Rehabilitation


The project envisaged the rehabilitation of the first drawbridge over the Neva River built in 1850 to the design of engineer Stanislaw Kierbedz and reconstructed in the 1930s to the design of Grigory Peredery.

The rehabilitation included replacement of the decks, extension of the draw span, dismantling of the tram rails and installation of the central reservation. The bridge was widened to 37 m and equipped with automatic barriers to stop traffic when the bridge is drawn.

During rehabilitation works, the bridge was restored to its original appearance and soon received back its original name. 

Bridge crossing over the Irtysh River Bridge crossing over the Irtysh River


The new road section with a bridge crossing over the Irtysh River links two roads (Pavlodar — Aksu and Omsk — Pavlodar — Maykapshaygay) and is part of the Centre — East Transport Corridor. The new bridge has become a landmark of the transit route from the Central Kazakhstan to Russia.

One of the main Stroyproekt’s tasks was to optimize the previously adopted design solutions. Implementation of net arches allowed reducing the section of bearing structural elements as compared to traditional arches with vertical suspenders. This gave significant cost savings due to reduction of material quantities, in particular, steel demand decreased by 5.5 thousand tons. 

Small Bridges in the Historical Centre of St. Petersburg: Review Small Bridges in the Historical Centre of St. Petersburg: Review

In the mid-1990s Institute Stroyproekt developed its first designs for rehabilitation and overhaul of historical bridges in the city centre. Since then Stroyproekt has often dealt with cultural and historical heritage monuments of the Northern Capital and this experience is extremely valuable for the company.
Troitsky Bridge in St. Petersburg Troitsky Bridge in St. Petersburg


The project was designed to rehabilitate the drawbridge over the Neva River built in 1903 to commemorate the 200th anniversary of St. Petersburg. Troitsky Bridge being a complex engineering structure with a distinguished Art Nouveau architectural decoration is the city’s heritage site.

The rehabilitation project envisaged ensuring high performance characteristics of the bridge while preserving its historical appearance. Some décor elements (railings, candelabra, etc.) were restored to the original sketches. Moreover, the unique method of ‘steel healing’ developed by Stroyproekt and Research Institute of Bridges allowed maintaining the original trough steel elements as left-in-place deck formwork.

Bridges of the State Palace of Congresses in Strelna Bridges of the State Palace of Congresses in Strelna

The project included restoration of a palace and park complex in Strelna and development of the State Palace of Congresses as a seaside residence of the Russian President.  The project schedule was extremely tight since the works had to be completed by the celebration of the city’s 300th anniversary.
