How the Western High-Speed Diameter Has Changed Petersburg’s Look

The central section of the ZSD (Western High-Speed Diameter) has almost been completed and looks as it will for years to come. Petersburgers are getting used to how the tollway’s tall bridges have altered familiar cityscapes.

Construction of the ZSD’s central portion was launched in 2013. By that time, the entire southern segment from the Ring Road to the Yekaterinagofka River had been opened to traffic, and a little while later, the ribbon was cut on the northern segment, which runs from Primorsky Prospect to the Scandinavian Highway. While the city built the southern and northern segments in the guise of Western High-Speed Diameter JSC, the most complicated section has been entrusted to Northern Capital Thoroughfare, Ltd., which is linked to VTB Bank and Gazprombank.

The length of the central portion is around 12 kilometers. It runs from the Yekateringofka River to Primorsky Prospect. The segment mostly consists of a series of bridges crossing the Neva Bay on high piers. It was designed by Stroyproyekt Institute JSC. The crossings over Petersburg’s two main fairways—the Petrine Fairway (in the mouth of the Malaya Neva River), and the Ship Fairway (in the mouth of the Neva River)—were built higher. The ZSD reaches its highest point when it passes over Kanonersky Island and the Sea Channel.

The height of the cable bridge across the Ship Fairway is 35 meters. The crossing is noteworthy for its inclined pylons. According to designers, they are supposed to resemble the drawbridges in Petersburg’s historic center.

Another of its distinguishing features is its visibility from the historic center. The chunks of concrete in a tight web of cables are visible over the Spit of Vasilyevsky Island if you look from the Liteiny Bridge; they can also be seen from the Admiralty.  In addition, the bridge has risen over the far end of Bolshoi Prospect on Vasilyevsky Island. The inclined pylons have had the greatest visual impact on the view down Bolshoi Prospect from northeast to southwest.

The cable bridge over the Petrine Fairway reaches a height of 25 meters. However, two of its pylons have risen to a height of 125 meters, which is slightly higher than the spire of the Peter and Paul Cathedral. In recent years, the cathedral has rapidly been losing its status as the city’s visual centerpiece. The tall pencil-like pylons can now be easily seen from the Islands.

The bridge crosses the Elagin Fairway at the mouth of the Bolshaya Nevka River. The bridge is situated at a height of sixteen meters, but that has sufficed to wipe out one of the oldest views of the Gulf of Finland, the view that once opened from the spit of Elagin Island. Whereas previously you could catch a glimpse of Kronstadt from the Central Park of Culture and Rest (TsPKiO) on a sunny day, you now must admire the highway.

This video provides a bird’s-eye view of construction of the ZSD over the Bolshaya Nevka River and the nearby Zenit Arena football stadium, on the spit of Krestovsky Island. Posted on YouTube by Alexander Parkhomenko on April 11, 2016, it was, apparently, filmed by a drone on October 18, 2015.

But as it crosses the Sea Channel, the bridge has come to tower over an entire island, Kanonersky. Its metal girders hang right over the island’s late-Soviet residential high-rises.  Some of the buildings will have to be resettled, but no buildings have been demolished yet and, most likely, none will be.

This stretch of the ZSD is the highest, because the main water route to the Neva (i.e., the one with the deepest fairway) runs through this part of town. The height of the span is 52 meters. Initially, it was planned to be slightly higher, 55 meters. It was lowered “to mitigate the highway’s longitudinal profile in order to ensure traffic safety on the approaches to the highest portion of the ZSD.”

The 52-meter mark was cleared with the United Construction Corporation and the management of the Port of Saint Petersburg. Nevertheless, a group of activists including Rear Admiral Igor Kolesnikov and Alexander Ivanov, Honorary Worker of the Soviet Marine Fleet, issued a statement that “the bridge clearances adopted in the draft project exclude the passage of large ships, vessels, and boats.”

In addition to the bridge, the face of the city has been impacted by another engineering decision made by the ZSD’s designers. As it passes the western edges of Vasilyevsky Island and the Island of the Decembrists, the road has been laid along the bottom of a ditch dug into the ground. Moreover, the road bed is essentially situated where ten years ago the waves of the Gulf of Finland washed the shoreline.

A tunnel was built under the mouth of the Smolenka River to construct this segment of the highway. It was built using the cut-and-cover method. Due to this fact, the Smolenka flowed into the gulf via two channels. While the tunnel was under construction, they were closed in turn to drain the water away. During the first phase, the tunnel was dug under the southern channel; during the second phase, under the northern channel.

The reclaimed lands to the west of the ZSD have been undergoing vigorous housing development, but they are cut off from main part of Vasilyevsky Island by the ZSD itself. The only link is Michmanskaya Street, which runs over the highway via an overpass, which was built before construction on the ZSD had begun. To improve transportation accessibility over the highway, two more bridges have been erected in the vicinity of Europe Square. For the time being, however, like the entire ZSD, they are fenced off and closed not only to traffic but also to pedestrians.

Under the investment agreement, the central section of the ZSD must be delivered this year. In the wee hours of August 9, a demonstration took place that involved securing the locking section of the road bed for the cable bridge over the Ship Fairway. Next, the final guy lines have to be adjusted and tightened, and the road bed must be asphalted.

According to the most recent statements by Petersburg city hall officials, the entire highway is scheduled to be open to traffic in November.

“Clouds Rose over the City,” from the film The Man with the Gun (1938), as sung by Mark Bernes:

Clouds rose over the city,
The smell of storm was in the air.
In faraway Narvskaya Zastava
Walked a young lad.

Ahead of me is a long, long road.
Come out, my dear, and say goodbye.
We’ll say our farewells in the door.
And you wish me luck on my way.
