Western High Speed Diameter (WHSD)

Western High Speed Diameter (WHSD)

St. Petersburg (new construction)
Design, detailed design
Project period: 2004 – 2016
General Designer: AO Institute Stroyproekt
Client: АО Western High Speed Diameter JCS


Description

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.

Main structures

Southern Section

An 8.7km-long stretch provides a link between the Ring Road and the seaport. About 90% of this road section are flyovers, bridges and overpasses as it runs through an extremely narrow corridor within industrial areas and the railway right-of-way. At some locations, the road passes at 25 m above the ground. Considering the confined space, our engineers suggested double deck horizontally curved trusses accommodating the carriageways of opposite traffic directions.

Northern Section

This road section, 26.4 km long, ensures new entrances and exits to/from the north of the city and a new exit to the resort area at the Gulf of Finland.

Central Section

The 11.7km-long Central Section is technically the most complicated part of the road running on bridges and flyovers over the Neva Bay.

It comprises:

Double-deck bridge over the Sea Channel

– length — 1020 m

– length of central span — 168 m

– bridge underclearance — 52 m

Cable-stayed bridge over Korabelny Fairway

– length — 620 m

– length of central span — 320 m

– bridge underclearance — 35 m

Cable-stayed bridge over Petrovsky Fairway

– length — 581 m

– length of central span — 240 m

– underbridge clearance — 25 m

Open-cut at Vasilievsky Island

– length — 2977 m

– depth — 7 m

– length of the tunnel under the Smolenka River — 290 m
