The present disclosure refers to an elevated track to support and serve the pneumatic propulsion duct for transportation vehicles, for cargo or passengers. The improved elevated track is modular and self supporting and consists of a pneumatic propulsion central duct (1) on whose vertical walls (11) are fastened side walkways (2). The propulsion duct (1) has structural reinforcing (12) in the form of transverse frames on the duct axis. The side walkways (2) have transverse reinforcement (21) which unify with the duct reinforcing frames (12). On the propulsion duct (1) top edges (13) are fastened rails (3) in an "I" beam format, traditionally used on railroads. A preferred transverse section of the propulsion duct (1) is rectangular, this having a central slot (14) on the top surface (13) for the passage of the vehicle propulsion system. Preferably, the side walkways (2) have protective handrails (4) and edges curved downwards (22) which with the central duct (1) define a covered area to shelter the pedestrians. One constructive option for the elevated track, formed with the propulsion duct (1) and the side walkways (2), which can be supported on pillars (5) positioned under the side walkways (2). In another constructive option, the elevated track can be suspended by vertical tie rods (6) fastened on the side walkways (2).
