Chronology

August 2007
— April 2009 |
In order to convert the bridge from a two-lane road bridge to a four-lane motorway bridge, the deck width is widened to about twice the original width by converting the single-cell box girder to a double-cell box girder. To do so a central web is added. Diagonals are added on the exterior to support the lengthened top slab cantilevers. These are counterbalanced by interior diagonals within the two cells. Vertical prestressing is added to the central web, transverse prestressing to the top slab and external prestressing along the longitudinal axis on the interior of the box. The diagonals are made of structural steel. |
