The documentation on the reconstruction of high-voltage power transmission lines for the construction of the SCHMSD has passed the state expertise

On March 14, 2025, the design and estimate documentation for the reconstruction of high-voltage power transmission lines in the section from Soyuzny Prospekt to the Ring Road received a positive conclusion from the FAA Glavgosexpertiza of Russia. The work is planned as part of the preparation of the territory for the construction of the Latitudinal High-speed Highway.

The reconstruction of high-voltage power transmission lines owned by PJSC ROSSETI was allocated to a separate design stage for the early implementation of the construction of the CMMSD.

The project documentation provides for the reconstruction of two 220 kV lines with a total length of 0.946 km and eight 330 kV lines with a total length of 6.598 km.

It should be recalled that the second and fourth stages of the CMMSD will go further east from the Vitebsk interchange of the WSD: the second stage – from Vitebsk Avenue to Soyuzny Avenue; the third – from Soyuzny Avenue to Kommuny Street; the fourth – from Kommuny Street (from the borders of St. Petersburg) to the Ring Road.

Thus, in accordance with the Master Plan for the Development of St. Petersburg, the SCHMSD, along with the Western High-Speed Diameter and the Ring Road, will ensure the withdrawal of transit traffic flows from the city center. Subsequently, the Latitudinal highway should connect with KAD-2.

The construction period of the 2nd – 3rd stages of the CMMSD is 2025-2029; stages 4.1, 4.2 are 2025-2031. The commissioning of the 2-4 stages of the CMMSD is 2029-2031. The deadline for commissioning the SCHMSD drawbridge in the alignment of Ash and Faiansovaya Streets is 2031.
