excuse me sir can you tell me how i can add joint to continuous bridge ?? 

[Rafal.Gaweda]

What do you mean by "joint" ?

[MUHANNAD.ABU_ABDO]

joints used in concrete between panels .. like expansion joint 

[Rafal.Gaweda]

Dilatation? Make gap between panels = separate panels with certain distance.
