Of the first nine million dollars ($9,000,000) required for the purpose of completing the project over and above the amount available from the sale of revenue bonds, the transfer shall be made from the above sources as follows:
Five-ninths from the State Highway Account, two-ninths from the funds mentioned in subdivision (b) and two-ninths from the amounts mentioned in subdivision (c). Additional necessary amounts shall be transferred from the State Highway Account upon resolution of the commission. The transfers shall be paid out or disbursed solely for the studies and expenses above mentioned and the preparation of the necessary surveys, plans, specifications, and estimates of cost, and for the construction of the toll bridge and the acquisition of the necessary lands and easements therefor. Any amount of the transfers not so expended shall be returned to the particular portion of the account from which it was transferred and shall be apportioned or allocated from the account and expended as if the transfer had not been made.
