A support and gripping apparatus for supporting traffic control signs to a concrete roadway abutment. The support has a plate which rests on the top of the abutment and which is held in place by a flange and adjustable grips which engage the abutment side wall. C-clamps are positioned along the plate. An adaptor is detachably securable to the plate and has a spring and vertically extending tube which carries the sign. Handles may be provided on the base to assist in moving and positioning the support. The adaptor may extend horizontally in cantilever fashion past the abutment side wall and having a group supported leg for additional stability. A wedge may be used by the installer to lift a glare screen if one is mounted on the abutment.
