St Petersburg link may include tunnel

A new alignment is being considered for a major project in Russia’s second city, St Petersburg. A tunnel stretch running under the Neva River is being considered as an alternative route for the Eastern High Speed Diameter (EHSD) project. This tunnel would take the place of the fixed bridge, which has been criticised by some for its impact on the city’s skyline. However building the tunnel would increase the cost of the project by around US$52 million.

A new alignment is being considered for a major project in Russia’s second city, St Petersburg.

This tunnel would take the place of the fixed bridge, which has been criticised by some for its impact on the city’s skyline. However building the tunnel would increase the cost of the project by around US$52 million. The 22.6km EHSD will carry 100,000 vehicles/day and will feature three lanes in either direction when it is complete. The route will connect with the Western High-Speed Diameter (WHSD) and the two will serve as a bypass around St Petersburg.
