The commission shall not issue turnpike revenue bonds, notes or other obligations to finance the costs of capital improvements projects unless the issuance thereof is approved by the General Assembly by passage of a concurrent resolution or unless bonds, notes or other obligations have heretofore been issued to finance the costs, in whole or in part, of such project and are otherwise authorized by existing statutes; except that the following projects are hereby approved, without further action by the General Assembly, for financing by issuance from time to time of bonds, notes or other obligations of the commission in an amount equal to the costs of the projects (now estimated to be approximately $163,500,000), a contingency reserve of 10%, issuance expenses and capitalized interest during construction:

The above improvements and estimated costs thereof are more completely described in the Pennsylvania Turnpike Commission's amended Capital Improvement Program, Volume II, dated January 1978. Bonds, notes or other obligations of the commission approved hereunder for issuance by the commission shall not be deemed to be a debt of the Commonwealth or a pledge of the faith and credit of the Commonwealth, but shall be payable solely from revenues of the commission, including tolls or other funds available to the commission for such purpose.
