The invention discloses a landscape bridge applied to an urban slow traffic system. The landscape bridge comprises support piers arranged at intervals, wherein beams are arranged on the tops of the support piers; the support piers are arranged along the direction of the built urban viaduct and positioned at road centerlines; the bottoms of the support piers buried below the ground are fixedly connected with foundation pile cushion caps; upper sections of support piers positioned above the ground obliquely extend towards two sides of the road so as to form a Y-shaped branched structure; a steelcross beam is horizontally arranged on the top of the branched sections of the support piers; the branched sections on two sides are connected into a whole by the steel cross beam; and the beams aresymmetrically arranged at two ends of the steel cross beam. The invention further discloses a construction method of the landscape bridge. The landscape bridge disclosed by the invention is ingeniousand reasonable in structure and attractive in appearance, and meets the urban aesthetic demands on the building structures. Meanwhile, the conventional urban three-dimensional space is fully utilized,the occupied land is small, and the landscape bridge is high in prefabrication degree, rapid in construction and small in city environment and traffic influences and has excellent social benefits.
