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.
