  • The bridge design

    The concept comprise an elegant extradosed bridge with inclined double pylons - offering an unique drivers experience. The bridge is supported on pile foundations where significant scour conditions have been catered for in the design. The continuous precast segmental girder is monolithically connected with four central pylons and supported on bearings at the outer most pylons and transition piers with expansion joints only at the abutments.

    The bridge is located near a seismic fault line demanding that capacity design is adopted for the bridge.

    The bridge concept won a 1st prize in an international competition in 2015.
