The Lefortovo tunnel was opened for traffic in December 2003. It was, of course, the most difficult engineering section of the third transport ring of the capital. The erection of this, in many ways unique, structures encountered great difficulties at the design stage. The route of the third transport ring was supposed to go through the old Moscow historical district of Lefortovo. And this fact provoked a lively public discussion on the topic of whether it is possible to sacrifice historical and cultural heritage for the convenience of driving. Public opinion then won, the freeway of the third transport ring under its pressure was forced to leave the surface of the earth in the Lefortovo tunnel. The visual appearance of the historical district of Lefortovo was not affected by it. But financially, such a project was very expensive.
Lefortovo tunnel, its engineering features
The construction of this structure continued for several years, and with its completion the third transport ring became closed. The length of the Lefortovo tunnel is 3 kilometers 200 meters. It passes under the historical building area Lefortovo, Lefortovo Park and the Yauza River. In a constructive sense, the Lefortovo tunnel is a combination of two tunnel underground spaces. The deep bed consists of three lanes, along it the transport goes north along the outer side of the third transport ring. And on the inside of the car, they move south in four lanes. The interior of this engineering structure is a combination of a flyover and a tunnel on different sections of the track.
The long underground track is equipped at a high level with security and life support systems. They include ventilation, lighting and sanitation. Throughout the underground space there is a gas control system. In case of fire, a forced-air emergency ventilation system is provided. The track is equipped with a video surveillance system for traffic flow in both directions. More than ten years of experience in operating this complex engineering structure allows us to state with confidence that the Lefortovo tunnel on the map of the
transport infrastructure of the capital is a positive example of an effective logistics solution. It allows you to optimally organize the intense flow of transport on a very busy section of the Moscow transport system.
Problems of the Lefortovo Tunnel
Not everything is going well in the field of traffic safety in both areas of this engineering structure. But the high accident rate here is mainly due to the irrational use of anti-icing reagents in winter. Slippery sections periodically appear on several sections of the route, which leads to numerous drifts and collisions. Especially with non-compliance with the speed limit.
