Because of a phenomenon called "freezing point depression." Dissolving any solute in a solvent causes that solvent to freeze at a lower temperature than it would if it were pure (it also causes the boiling point to go UP). The salt in saltwater causes this effect. The amount the freezing point changes depends on the amount of dissolved salt.
