The SHSD bridge will have the longest drawbridge span

Chairman of the Investment Committee of St. Petersburg Ivan Skladchikov, in an interview with the Rossiya 1 TV channel, spoke about the features of the bridge, which will be built as part of the High-Speed Latitudinal Highway (SHMSD). The day of preparation for the broadcast of the Vesti - Saint Petersburg program was not chosen by chance - deputies of the city Parliament approved in the first reading the idea to fix a new professional holiday for December 4 - the Day of the Bridge Construction Worker. The date is connected with a historical event: on this day in 1850, the Blagoveshchensk Bridge was opened – the first permanent crossing of the Neva River in the city.
The SCHMSD Bridge will continue the traditions of the historical crossings of the city and, together with the Bolshoy Smolensky Bridge, will become a new drawbridge built in the Northern capital over the past 40 years.
"St. Petersburg is truly a city of drawbridges – we have presented and continue to create engineering structures and structures that have no analogues. The SCHMSD bridge has its own unique distinctive feature – the length of its draw span will be 60.1 meters – it will be the longest draw wing, no other bridge in St. Petersburg has such a thing anymore," Ivan Skladchikov noted.
At the same time, a navigable dimension of 55 meters will be provided, and the lifting/guidance time of such a huge draw span of the SCHMSD bridge corresponds to standard characteristics for modern bridges and will be about three minutes.
The drawbridge span of the SCHMSD bridge is designed as a single-wing drop-down system. The bridge will have a non-classical layout. This is due to the fact that the bridge will actually be part of a road that has three lanes in each direction, as well as a separation between directions. Therefore, each of the spans will rise as an independent system, taking into account the direction of movement.
The wiring/guidance schedule will be adjusted based on navigation. In addition, the bridge design takes into account the difficult navigation conditions on the Neva River and will allow for the wiring of ships without restrictions.
Another, no less significant feature is that the project assumes a low-water drawbridge structure. The need to minimize the construction height of the bridge is due to the location next to the monument of history and culture of regional importance - the Finnish Railway Bridge. Due to specially thought-out architectural structures, the new SCHMSD bridge will visually merge with the architecture of the Finnish Railway Bridge, without disturbing panoramic views, including cultural heritage sites.
The bridge as part of the SCHMSD will connect the banks of the Neva River in the alignment of Ash and Faience streets. The length of the bridge, excluding approaches, will be 462.7 meters. The construction of the bridge is included in stage 4.1, within the framework of the concession agreement, the planned start date of this stage is 2025.
Thanks to the construction of a new crossing over the Neva River and the redistribution of traffic flows, the load on existing bridges in this part of the city, in particular on Volodarsky and Alexander Nevsky Bridge, will decrease.
Recall that the signing of the concession agreement for the construction of 2-4 stages of the CMMSD took place in Moscow on November 20, 2024, within the framework of the International Forum and Exhibition "Transport of Russia".
