OPINION OF THE COURT
Appellant brought the present action to recover damages for personal injuries. In his complaint he alleged that while operating a tractor-trailer for his employer along the Pennsylvania Turnpike the vehicle struck a large hole in the roadway, causing the truck to veer off the road and down an embankment, and resulting in personal injuries to him. Appellee Turnpike Commission was charged with negligently failing to maintain the roadway in a reasonably safe condition. Federal jurisdiction was based on diversity of citizenship. 1
*1334
The district court, on appellee’s motion, dismissed the complaint on the ground that appellant failed to state a cause of action upon which relief could be granted. The basis for the dismissal was the Pennsylvania Supreme Court’s decision in Rader v. Pennsylvania Turnpike Comm’n,
In dismissing the complaint on the ground that the Turnpike Commission was immune from liability the district court acted correctly. Whether or not the Commission is immune from the tort liability posited here is a question
*1335
of state law,
2
and under Erie R. R. Co. v. Tompkins,
In his brief and at oral argument appellant also raised constitutional claims bottomed on the Fourteenth Amendment. In Ewalt v. Pennsylvania Turnpike Comm’n,
Appellant contends that while a state may effect a partial waiver of immunity from tort liability, it may not waive that immunity in such a way as to treat differently persons similarly situated.
5
Assuming this to be the rule, we do not find the partial waiver here, in effect a form of classification, to be unreasonable. While the precise question presented here does not seem to have arisen previously,
6
we note that the equal protection clause “is offended only if the classification rests on grounds wholly irrelevant to the achievement of the State’s objective,” McGowan v. Maryland,
Appellant also makes a due process argument, contending that the application of the turnpike statute in question so as to deny him any redress for the personal injuries received as a result of the negligence of the Pennsylvania Turnpike Commission deprives him of “that fundamental fairness and justice required under the due process clause.” Brief, p. 12.
In Palmer v. Ohio,
To appellant’s plea that we re-examine the doctrine of governmental immunity from tort liability in light of Pennsylvania’s abolition of charitable immunity in Flagiello v. Pennsylvania Hospital,
Such a course may be desirable. But it is not now sufficiently foreshadowed in Pennsylvania decisions to justify a federal court applying Pennsylvania law in a diversity case in holding that Pennsylvania law subjects municipalities [here the Turnpike Commission] to liability * * *. 8
The order of the district court to dismiss the complaint will be affirmed.
Notes
. While not specifically asserting the Eleventh Amendment, appellee, in its brief, appears to be relying, in part, on the “sovereign immunity” of the Turnpike Commission. Appellant, in turn, asks us to resolve the Commission’s immunity under the Eleventh Amendment. The reference to the Eleventh Amendment, which deals with, suits against states in federal courts, puts the jurisdiction of the district court here in question by suggesting that the Turnpike Commission is the alter ego of the Commonwealth of Pennsylvania. Since neither a state nor its alter ego is a citizen for purposes of diversity jurisdiction, a suit between a state, or its alter
*1334
ego, and a citizen of another state is not a suit between citizens of different states and diversity jurisdiction does not exist. State Highway Comm’n v. Utah Constr. Co.,
Even if a state waives its Eleventh Amendment immunity to suit, as it has the power to do, Petty v. Tennessee-Missouri Bridge Comm’n,
Whether or not an agency or instrumentality is the alter ego of the state and, therefore, immune from suit by virtue of the Eleventh Amendment is a question of federal, not state, law. Pennsylvania Turnpike Comm’n v. Welsh,
Because we dispose of the appeal here on the ground of immunity from, tort liability, we do not decide the jurisdictional issue. Thus we need not grapple with the question of what effect, if any, the Pennsylvania Supreme Court’s decision in Rader v. Pennsylvania Turnpike Comm’n,
. Gerr v. Emrick,
Por a
pre-Rader
discussion of the “liability and suability” of turnpike agencies, pointing up the distinction between immunity from
suit
and immunity from
liaMlity,
see Annot.,
. See Burke v. Washington Hospital Center,
. The Pennsylvania Supreme Court was applying § 6(k) of the Western Pennsylvania Turnpike Extension Act of June 11, 1941, P.L. 101, Pa.Stat.Ann. tit. 36, § 654e(k), which provides that
all public or private property damaged or destroyed in carrying out the powers granted by this act [the construction, operation and maintenance of the Turnpike] shall be restored or repaired and placed in their original condition as nearly as practicable or adequate compensation made therefor out of funds provided under the authority of this act.
While the Court was very careful in
Ewalt
in denominating the recovery as one for a continuing trespass because problems of statutory construction may have precluded the claim as consequential damages under eminent domain, the State Supreme Court later recognized the true nature of the relief granted, making it markedly different from the kind of relief sought here. In Valley Forge Gardens, Inc. v. James D. Morrissey, Inc.,
We held [in Ewalt] that the Commission was liable for the proven consequential damages because the * * * [applicable act] expressly charged the Commission with the payment of compensation for property damaged or destroyed by the construction, operation and maintenance of the turnpike.

. In Beers v. Arkansas,
. In fact, tlie Pennsylvania Supreme Court has very recently reaffirmed the holding in
Rader
in Thomas v. Baird,
* * * Moreover, Rader has been cited with approval by our Court several times, and its rationale applied to other factual situations.
Por example, we granted sovereign immunity to the General State Authority (Roney v. General State Authority,413 Pa. 218 , 219,196 A.2d 349 ) ; to the Delaware River Port Authority (Anderson Appeal,408 Pa. 179 , 187,182 A.2d 514 ) ; and to the State Highway and Bridge Authority (Eidemiller, Inc. v. State Highway and Bridge Authority,408 Pa. 195 ,182 A.2d 911 ).
Rader
is firmly established as the law of Pennsylvania and no convincing reasons have been advanced for overruling it or changing the law.
