About the book: year / The current approach in the world to separate movement along transport corridors of motor vehicles, railway transport, pipeline wiring, communication systems, electricity is expensive , is largely ineffective, often takes away fertile land from users, pollutes the environment, and uses outdated methods of moving vehicles. Identification of the shortcomings of this approach made it possible to develop new compact road structures that ensure non-stop movement of vehicles in a single volume of a combined transport pile overpass based on a steel frame through the introduction of end-to-end buffer strips for trains and cars and interfloor crossings for cars. It has also become possible to use the structure for hanging cables and pipelines on it. A similar design can be used as an overpass. These and similar structures will make it possible to sharply intensify trade turnover, will be an additional market for rolled metal and cement, will allow the development of desert territories and will significantly increase mobility and improve the lives of the population.
