Design, Detailed Design, Construction Supervision
St. Petersburg (new construction)
Project period: 1999 – 2014
General Designer: Institute Stroyproekt
Client: FKU Directorate for Construction of St. Petersburg Bypass
The Ring Road is the first express highway in St. Petersburg, which allowed diverting transit traffic away from the city. Part of the road runs along the Flood Protection Barrier.
Stroyproekt developed the design of engineering structures and carried out construction supervision on several road sections and traffic interchanges.
Length — 142.15 km
Category — IА
Design speed — 120 km/h
Lanes — 4–8
Interchanges — 31
Engineering structures — over 100

When back in 1999 Stroyproekt was developing the design for St. Petersburg Ring Road interchange with Primorsky roadway near Gorskaya railway station, we proposed composite structures not only for the main overpass but also for curved ramps of 60 m radius. It was an innovation as well since curved beams were considered to be difficult to manufacture. However, our solution was successfully realised and later on we have often used it when designing the Ring Road facilities.
At that time construction of the Ring Road that had been awaited by the city for such a long time had just started, and we tried to make the Gorskaya interchange architecturally easy recognisable. We were not required to do so; it was our own initiative. White А-shaped (or trapezoid) pylons imitating entrance gates made this large structure look light and stylistically complete. This interchange opened in 2001 became a symbol of a new stage of the Northern Capital transport development that had begun with the Ring Road construction.
The most complicated structure of the Ring Road is a cable stayed Big Obukhovsky Bridge over the Neva. Its river span is 382 m long. The bridge has become the first fixed bridge across the Neva. 16 companies, including Danish and Finnish ones, have participated in its design. Stroyproekt was a General Designer of the bridge.
