FIELD: construction engineering. SUBSTANCE: this relates to design of ring highways of large cities or megapolices together with suburbs such as Moscow. Ring highway in plan has its axial line configured in the form of endless curve with predetermined ratio of its sectional lengths, each provided with optimal number of various artificial structures such as medium and small bridges, overpasses, tunnels, separate level crossings, overground and underground pedestrian passages. At least three combination crossings are made in three levels and at least one combination crossing is in four levels. Method for reconstruction of ring highway implies remodelling of existing structures or building new structures without stopping vehicle traffic with producing five traffic lines in either direction with optimal number of artificial structures per 1 km of highway and optimal ratio of separate type of artificial structures. Realization of given invention allows for cutting labour and material costs, with optimal selection of composition of asphalt-concrete for pavement, optimal redistribution of traffic flows at crossing with other motor roads, providing conditions for convenient and safety crossing of highway by vehicles and pedestrians with simultaneous improvement of ecological situation and prolonging periods between repairs. EFFECT: higher efficiency. 20 cl, 176 dwg
