The ring road around St. Petersburg (A118, KAD) is a federal highway passing through the territory of St. Petersburg and the Leningrad Region. The highway connects all the main highways going from the city center in the direction of Helsinki, Murmansk, Moscow, Kiev and Tallinn.
Lengiprotrans took part in the design of the head section of the Ring Road - from the Gorskaya station (Sestroretsk city) near Primorskoye Highway to Priozerskoye Highway, including a complex junction at the intersection with Vyborgskoye Highway. The section of the road passes through the Kurortny, Primorsky, Vyborgsky districts of St. Petersburg and the Vsevolozhsky district of the Leningrad region.
The Institute carried out the main work on the survey of the route, the development of working documentation for the subgrade and pavement, and also designed an automobile overpass across the Ring Road.
The total length of the section is 21.6 km, the number of traffic lanes is 4 (for the future, 6 lanes).
At the end of 2001, the ring road section was put into permanent operation.
