The Dabar Bridge is located between the Šibenik and Vrpolje interchanges of the A1 motorway in the Dalmatia region of Croatia. It is a long concrete girder bridge spanning the Dabar flash flood gully at a height of .〔 The bridge is long overall, executed across 7 spans ( + 5 x + ). Axis of the bridge is in a horizontal circular curve in diameter. The cross section of the bridge comprises two dilated structures, each carrying one motorway carriageway consisting of two wide traffic lanes and one wide emergency lane. The bridge is wide overall. ==Construction== The deck structure consists of longitudinal girders, cross-girders, and the deck. The abutments and the outermost piers support the structure through bearings while the remaining four piers are fixed to the deck structure. The longitudinal girders are executed as prefabricated, pretensioned girders and there are 10 longitudinal girders comprising the cross-section of the bridge, i.e. five of them, with axes set apart, supporting each of the carriageways. Length of the prefabricated girders ranges from to in the peripheral spans and between and in the remaining spans. The girders are high I-sections with wide upper flange. The bottom flange of the longitudinal girders is wide. The longitudinal girders were manufactured in a special plant next to the bridge construction site and placed in the bridge structure using incremental launching. Bridge piers comprise a box cross-section measuring by with a constant wall thickness of . The top of each of the piers is closed by an Omnia slab deep. Each motorway carriageway is supported by a separate set of piers. The abutments, on the other hand, are designed to support both of the carriageways. The cross-girders are placed at the abutments and the piers. The Dabar Bridge was designed by Jure Radnić and constructed by Hidroelektra niskogradnja, Zagreb. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dabar Bridge」の詳細全文を読む スポンサード リンク
