A hollow cooled turbine airfoil (18) is provided having pressure and suction side walls (20, 22) and a plurality of trailing edge cooling passages (46) that feed cooling air bleed slots (28) at the trailing edge (26). The trailing edge (26) is selectively thickened in the root (34) portion so as to allow shortened trailing edge slots (28), thereby improving trailing edge (26) cooling and reducing mechanical and thermal stresses.
