The thickness of the composite concrete deck slab on deck type bridges typically will be 250mm. An in-situ slab of this thickness, cast either on timber formwork or permanent formwork, will span around 3.5m, hence girder spacing (main girders in multi-girder decks , cross girders in ladder deck systems) will typically be at 3.5m centres, or a little more as the slab spans between the flange outstands.

Case 2 illustrates how to set the deck thickness at supports for a side-by-side box girder bridge. The deck thickness at supports is set and verified with similar methodology used to set girder haunches, but without the need to accommodate partial depth deck panels.

Effects of Bridge Deck Thickness on Properties and

May 02, 2003 · About two years ago, the Alabama Department of Transportation (ALDOT) increased its minimum bridge deck thickness to 178 mm (7 in.), and thus ALDOTs deck thicknesses now range from 178 to 197 mm (77.75 in.).
