The viaduct is a box girder structure supporting the deck across nineteen spans: two of , sixteen of and one of . The viaduct piers range from to in height. The superstructure of the viaduct comprises a box cross section made from pre-stressed reinforced concrete, put in place by incremental launching due to the considerable height of the structure. The launching was carried out downhill, because of the substantial grade of the superstructure, with two VBT 19×140 cable stays as a braking mechanism for the box girder. The cross-sections of the box girder and the piers are virtually identical to those of Bajer Bridge.
