A submerged tunnel with buoyant suspension (1) for a road and/or rail connection between two shores (2) which are separated by an expanse of water (3) and in the region of which the tunnel (1) has respective ends (4) comprises a plurality of tubular modules (5) of predetermined axis which are connected to one another rigidly head to tail and are anchored to a bed (39) of the expanse of water (3) between the shores (2) in order to resist buoyancy. Advantageously, the ends (4) of the tunnel (1) are associated, with sliding and hinged engagement, with connecting structures (6) fixedly joined to the shores (2), while a hinged joint (26) sub-dividing the tunnel into two rigid portions which are articulated relative to one another to a limited extent about that joint is inserted between two adjacent modules (23, 24) located in the region of the middle of the tunnel (1).
