The invention discloses a gravity slide type overpass, and belongs to the field of building facilities. The structure of the gravity slide type overpass comprises an overpass body, inclined rails, stairs, gravity slides and deceleration transmission systems, wherein the overpass body stretches across a street; the stairs are respectively arranged at the two ends of the overpass body; a guardrail is arranged at the outer side of the overpass body; the inclined rails are mounted along the outer sides of the stairs; conveying belts are arranged on the inclined rails; the upper ends of the inclined rails are bearing platforms, and the tail ends of the inclined rails are buffer platforms; the gravity slides are respectively mounted on the bearing platforms and the buffer platforms, are arranged on the conveying belts, and are vertically transmitted in the inclined rails through the conveying belts; and the deceleration transmission systems are arranged at the lower parts of the buffer platforms, and are connected with the conveying belts. The gravity slide type overpass solves the defects of single function and waste of time and physical power in a common overpass, has such characteristics as time saving and power saving, and can cultivate the mutual assistance consciousness of people.
