Zusammenfassung:	A submerged tunnel bridge with positive buoyancy is anchored to the sea bottom. The bridge comprises spaced anchoring pontoons anchored to the sea bottom and operative to provide sufficient buoyancy for the submerged tunnel bridge, and bridge sections in the shape of tube-shaped tunnel sections mounted between the anchoring pontoons, the tunnel sections having such weight and buoyancy that net vertical force on the tunnel bridge sections with varying internal and external loads will vary in a range around zero.
