Abstract

L'invention porte sur un pont composite ou sur un tunnel composite pour circulation à droite, lequel pont ou tunnel est constitué par deux unités en forme de « T », et est constitué par deux ponts ou tunnels de bifurcation indépendants, et est utilisé pour une conduite sans croisement de véhicules opposés circulant en ligne droite et tournant à gauche à un carrefour. Un pont de virage à gauche (3) est situé du côté gauche d'un pont à arche en ligne droite (2), et forme un pont de bifurcation en forme de « T » (1) bifurquant de façon synclastique. Deux ponts de bifurcation en forme de « T » (1) bifurquant de façon synclastique avec des fourches opposées forment le pont composite. Une section d'une voie en sens unique du pont à arche en ligne droite (2) est située dans la fourche du pont de bifurcation en forme de « T » opposé (1) bifurquant de façon synclastique.
