FIELD: motorway engineering. SUBSTANCE: motorway used in erection and reconstruction of crossover junctions at different levels of motorway under conditions of close city development, presence of nearby historical and architectural monuments, and miscellaneous underground service lines has earth-based sections, road interchanges, and/or bridge crossover, and/or motorway tunnel sections. Novelty is that one tunnel section has two sections curvilinear as viewed from top with their convex parts facing opposite sides; intermediate rectilinear section and rectilinear end sections are formed between them; angle between axis of one rectilinear end section and that of intermediate rectilinear part is 39- 47 deg; angle between axis of other rectilinear end section and that of intermediate part is 23-31 deg.; total length of tunnel section footlights is 0.100-0.105 of entire length of tunnel section. EFFECT: reduced labor and material consumption, scope of earth excavation; enhanced carrying capacity and safety of traffic; eliminated traffic congestions, deformations of earth-based structures; improved environmental friendliness. 13 cl, 12 dwg
