The department shall have authority to enter into contracts with any public service company for the construction as a part of any existing bridge or of any bridge to be hereafter constructed under the provisions of this act, of such structure or equipment as may be necessary to accommodate the facilities of the company, but the company shall in every such case pay in full the cost of such structure or equipment. The department shall also have authority to issue licenses for such length of time and for such fee, for the occupancy of any bridge by the facilities of any public service company, as may be determined by the secretary, with the approval of the Governor, under the provisions of existing laws. The payment by any public service company of the cost of such structure or equipment as may be necessary for the accommodation of its lines shall not confer upon such company any rights except those expressly conferred upon it by the license issued to it as hereinbefore provided. All fees collected under such licenses shall include the costs of issuance of the license, inspection of the work, and restoration charges, in addition to rental for the occupancy of the bridge, and, when collected, shall be credited to the Motor License Fund.

If any agreement or contract has heretofore been made or entered into between any county and any public service company for occupancy of any such bridge, such agreement or contract shall remain in force and the State shall take over and succeed to all the rights of the county under such agreement or contract. Where such contract provides for the payment of a certain amount for such occupancy, payment shall be made by the company to the Commonwealth; and if payment has already been made to the county in full for any specified length of time extending beyond the date of approval of this act, the proportionate amount of the payment represented thereby shall be paid by the county to the Commonwealth, and the department shall not be authorized to assume the obligation for construction or maintenance of such bridge until and unless such payment is made by the county. All payments made to the Commonwealth as herein provided shall be credited to the Motor License Fund.
