Cable-stayed bridge bridge has some similarity in principle to the cable-stayed type in that tension forces that prevent the deck from dropping are converted into compression forces vertically in the tower and horizontally along the deck structure. It is also related to the suspension bridge in having arcuate main cables with suspender cables, although the self-anchored type lacks the heavy cable anchorages of the ordinary suspension bridge. Unlike either a cable-stayed bridge or a suspension bridge, the self-anchored suspension bridge must be supported by falsework during construction and so it is more expensive to construct.

Baltic Cable the only crossing of two submarine HVDC cables in the Baltic Sea and one of the only few worldwide. From the landing point at the southern coast of Sweden at , the Baltic-Cable runs a further as an underground cable until a point east of the road E6 at , where inside a fenced area the transition from underground cable to overhead powerline takes place. From there the powerline runs as overhead line over two suspension pylons in north-northwesterly direction until the first strainer at . There the line turns into north-northeasterly direction and runs over seven suspension pylons past
