If the director of transportation enters a finding and determination for a proposed grade crossing improvement the railroad companies involved in such proceedings shall co-operate with the director in the preparation of plans and specifications covering the construction of the proposed project. Such companies shall furnish such plans, specifications, and approximate estimates as the director directs. In changing the grade of any railroad, no grade shall be required in excess of that adopted by a company for the construction of its tracks on the division or part of the railroad on which the improvement is to be made without the consent of the company, nor shall the tracks of any company, or the grade of any road or highway on the state highway system, or any extension thereof, be required to be placed below high-water elevation, except by mutual agreement.
