Client: Western High Speed Diameter JSC
Description
St. Petersburg Master Plan envisages that the East-West Highway together with the Western High Speed Diameter (WHSD) and the Ring Road will form the network of urban highways. The highway is designed to ensure a new transport link between the city centre and outskirts. WHSD and the East-West Highway will create a bypass diverting transit traffic from the centre of St. Petersburg to the network of highways and throughfares.
The planned highway will include a bridge over the Neva to be built between the Alexander Nevsky Bridge and Volodarsky Bridge, which are located at 6.5 km from each other. The new bridge will relieve congestion at the approaches to these bridges and improve the traffic situation in the area.

Western High Speed Diameter (WHSD) 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.
