This study is done to develop a set of consistent design guidelines for self-anchored suspension bridges and discusses static behaviour as well as feasibility study of long span self-anchored bridges. In order to accomplish this goal, a thorough investigation of important parameters to determine behaviour of self-anchored suspension bridge and identify any gaps on current knowledge is done to be filled in order to enable the formation of a consistent set of design recommendations. This research indicated that a well-chosen ratio between the bending stiffness of deck and axial stiffness of cable influences the maximum bending moments and the deflections in the girder. The ratio of sag to span is also investigated to reduce the normal force in the deck and the maximum bending moment in the deck. A study to the static strength, stiffness, frequency behaviour and the buckling stability of the box girder, revealed that a deck slenderness of the box girder of λ = 1/100 and even more slender is very well feasible. The paper also discusses possibilities of increasing main span length and tries to find a certain span limit for the self-anchored suspension bridges. Increasing the span length of the bridge will cause several effects on static strength and stiffness. Several effects are monitored like stresses in cable, girder and pylon, deformations and reaction forces. Based on results of this study, a span length of 500 metres is very well possible and even beyond that.
