Western High Speed Diameter

Western High Speed Diameter

St. Petersburg (new construction)
Design, detailed design development and construction control
Project period: 2004 – 2016
General Designer: AO Institute Stroyproekt
Client: Concessioner of the WHSD Central Part is North Capital Highway LLC, OAO WHSD


This modern multi-lane highway connects the southwest of the city, including the Sea Port area, with the Ring Road, Vasilievsky Island, Kurortny district and the Scandinavia motorway. This is one of the first projects in Russia carried out on concession basis. The WHSD is a toll road.

The WHSD motorway runs from the South to the North from the intersection of St. Petersburg Ring Road with Dachny prospect along the railway tracks of Baltic semicircle via Kirovsky Plant to the Timber Port, then across the Gulf of Finland and along the western part of Vasiljevsky Island and Petrogradsky District, in the territory of Primorsky and Vyborgsky District (crossing the Ring Road near Hyundai plant) Карта_КАД+ЗСД.jpgand ends up at the junction to E-18 Scandinavia motorway near Beloostrov (Kurortny District).

The road includes a great number of engineering structures to cross the densely developed urban territory and water areas, including the vast spaces of the Neva Bay.

The Western High Speed Diameter owns two records for the largest length of bridge structures in Russia:

 1. The longest bridge structure in Russia is the southern flyover of the main way with the bridges across the Sea Channel and Korabelny Fairway - 9378 meters.
 2. The second place in terms of the length is the northern flyover of the main way with the bridges across the Petrovsky Canal and Elagin Fairway - 8794.475 meters.

Main parameters:

 – Total length: 47 km;
 – Number of lanes at different sections: from 4 до 8 (in both directions);
 – Maximum traffic intensity: 140,000 vehicles per day;
 – Total length of bridges, overpasses, tunnels: 21 km;
 – Number of traffic interchanges: 14 (including 6 interchanges to be constructed later).

The WHSD project includes construction of unique bridge structures in Russia, which are an integral part of the St. Petersburg Sea Façade:

• Double Deck Bridge across the main navigation channel of the city – the Sea Channel
 – bridge length: 734 m
 – length of the central span: 168 m
 – bridge underclearance: 52 m

• Cable-stayed bridge across the Korabelny Fairway
 – bridge length: 620 m
 – length of central span:  320 m
 – bridge undercelarance:  35 m

• Cable-stayed bridge across the Petrovsky Fairway
 – bridge length: 580 m
 – length of central span:  240 m
 – bridge underclearance:  25 m.

As regards aesthetic aspects, the entire road has a common design which is dynamic and recognisable: arch-like lighting supports are combined with curved noise screens.
Therefore the WHSD is perceived not only as a highway but as an integral engineering and architectural complex.

The WHSD is one of the first toll roads in Russia and the first one in St. Petersburg.

The WHSD construction:

Construction works were carried out since autumn 2005.
The WHSD Stage I was commissioned on 30 October 2008.

In May 2011 toll operation started at the opened section of the WHSD (Stage I and part of Stage II up to Blagodatnaya Street). The toll can be paid at specially fitted checking points in cash, by bank or smart cards or using electronic payments.

On 18 September 2010 a small section of Stage III between the Hyundai automobile factory and the Ring Road was opened for operation.

On 14 October 2010, section of Stage II up to Blagodatnaya Street was opened for traffic.

On 29 December 2011, the traffic interchange at the intersection of the Ring Road with the WHSD at Hyundai automobile factory was partially opened for traffic.

On 10 October 2012 a section of stage II from Blagodatnaya Street to the Ekaterngofka River was commissioned. Thus the whole Southern Section of the route was put into operation.

In 2013 construction of the Central Section was started.

On 02 August 2013 the WHSD Northern Section from Primorsky road junction to Beloostrov was opened for traffic.

On 02 December 2016 the WHSD Central Section was opened for traffic.

The WHSD is an innovative project from various standpoints. It is the first expressway, which connected the southern and northern outskirts of St. Petersburg to the city centre. Besides, it is also the first toll motorway of the Northern Capital of Russia.

The WHSD project includes unique bridge structures that formed up St. Petersburg Sea Façade.

The major part of the WHSD route is located in a narrow corridor across compact industrial areas. Lack of free space was the most pronounced at the section from Stacheck Prospect to the Ekaterinhofka River (Construction Stage II). To cope with these constraints our designers have proposed double-deck trusses for this section and also for some Stage IV sections. Double deck trusses allow separating opposite traffic flows to the lower and upper deck correspondingly (providing 4 lanes in either traffic direction). Horizontally, the trusses are located on a variable radius curve with superelevation and transition zones, which is very unusual for double deck structures. The longest span is 144 m.

The WHSD design includes some other solutions which are not so large-scale but still quite interesting. As an example the toll plaza at the exit ramp to Automobilnaya Street (Stage I) can be taken which has been constructed on two levels due to the extremely space-lim ited area.

Aesthetically the WHSD route has been designed in a uniform, recognisable and dynamic mode: arc-shaped lighting poles are integrated with curved noise screens. For this reason the WHSD is perceived not just as a long-distance motorway but as a continuous engineering and architectural complex.



Stroyproekt will design new interchanges on WHSD 06.02.2017 Stroyproekt will design new interchanges on WHSD

Institute Stroyproekt has concluded a design contract for three traffic interchanges on the Western High Speed Diameter (WHSD) in St. Petersburg.
