The main part of footbridge structure is situated above the Q100 water level due to significant curvature in vertical plane , but at the same time the mass of the bridge approaches is minimized. The appearance of the bridge gives the impression of lightness . The superstructure is stabilized vertically by pretensioned cables following the curvature of the footbridge. Cabel induced radial forces increase the rigidity of the suspension system.

The construction is single span earth anchored suspension system with the span of 62,36m. The cable system comprises parabolic main cable and two short free cables anchored to the earth by anchor blocks and pretensioned rock anchers. The pylons are inclined, concrete abutments are founded on drilled micropiles and covered by stone. Steel superstructure was erected symetrically from pylons toward the centre of span from preassembled segments of 5,0m length. The wooden carriageway of 3,0m width is made of oak lumber. Railings in the shape of St.Andrew’s cross is made of larch lumber.
