FIELD: transport engineering. SUBSTANCE: invention relates to transportation systems with track structures of monorail and overhead tyopes and it can be used for building high speed city and inter-city roads including those laid in rough terrains, mountains, deserts and in building multirail or monorail intershop transportation structures of distributed enterprises to combine them into common structure. In proposed transportation system containing at least one main line secured on supports and made in form of prestressed power member enclosed in housing with mating rolling surface for running vehicles and at least one auxiliary line with prestressed power member secured on supports at other, relative to main line, level, said main and auxiliary lines are rigidly interconnected over entire span between adjacent supports by means of rod of preiodically crisscross orientated rod members whose longitudinal axes form triangles with longitudinal axes of main and auxiliary lines. According to other design version of transportation system, main and auxiliary lines are arranged equidistantly over entire length of span, and auxiliary line secured under main line is provided with at least one side rolling surface. EFFECT: increased length of span between adjacent supports at preservation o speed characteristics of transportation system. 13 cl, 26 dwg
