Opinion,

This case is before us in our original jurisdiction. It is a suit against the Commonwealth, in trespass, alleging negligence in failing to properly warn drivers of a dangerous curve and failure to provide an adequate guardrail and shoulder area.

The Commonwealth has filed preliminary objections based on sovereign immunity. The preliminary objections must be sustained. See Biello v. Pennsylvania Liquor Control Board, 454 Pa. 179, 301 A.2d 849 (1973) ; Brown v. Commonwealth, 453 Pa. 566, 305 A.2d 868 (1973).
