Creation and operation on the basis of public-private partnership of the highway " Western high-speed diameter"
Sphere of activity: Transport infrastructure
The Project aims to construct an intracity multi‑lane toll road to connect the south section of the Ring Road with its north section and the Scandinavia Highway. The highway will reduce the time to drive through the 5‑million megacity to less than 20 minutes without breaking the traffic rules, provide an access to the Big Sea Port and to the busiest federal roads, reduce traffic load on the city’s historical centre, the Ring Road, and the road network.
The north and south sections of the highway have been commissioned and transferred to Northern Capital Highway for operation as a toll road. Currently, construction of the most technically challenging section, the Central section, is underway.
Each section of the Western High‑Speed Diameter daily serves up to 80,000 cars, and both sections combined serve up to 4 million cars per month.
The section runs from the Ring Road intersection in the south to the Ekateringofka River, with a total length of 8.5 km. The section has four junctions.
Starting from 1 December 2013, the South ZSD section has been operated by Northern Capital Highway, the Partner under the Agreement for Construction and Operation of Western High Speed Diameter Highway through a Public‑Private Partnership.
The section runs from the Bolshaya Nevka River to Е‑18 Scandinavia Highway, with a total length of 26.4 km. The section has four junctions.
The North section was launched in August 2013 and transferred to the Partner for operation in 2014; a toll collection system on a zonal basis was introduced.
The Central section runs from the Ekateringofka River along the western end of the Vasilyevsky Island to the right bank of the Bolshaya Nevka River. The most technically challenging 11.7 km section will complete the SZD as a drive‑through road and ensure a by‑pass road around Saint Petersburg’s historical centre for transit vehicles.
The section design provides for unique bridges in the Neva Bay:
- Double‑deck bridge across the Sea Canal (length: 759 m, central span: 168 m, bridge clearance: 52 m);
- Cable‑stayed bridge across the Korabelny Fairway on the Bolshaya Neva River (length: 622 m, central span: 320 m, clearance: 35 m, pillar height: 125 m);
- Cut‑and‑cover tunnel underneath the Smolenka River (length: 400 m, lower deck depth: 13 m);
- Cable‑stayed bridge across the Petrovsky Fairway (the Malaya Neva and Malaya Nevka outfall) (length: 600 m, central span: 240 m, clearance: 25 m, pillar height: 125 m).
- Number of junctions: 14
- Number of lanes: 4–8
- Estimated driving speed: 110 km per hour
- Capacity: up to 128,000 cars per day
- Traffic on commissioned sections: 80,000 cars per day, 4 million cars per month
The project is financed by the budget and based on the Private‑Public Partnership Agreement with Northern Capital Highway.
