Mich. Comp. Laws § 46.23
Whenever any person or persons, township officers or corporation, shall wish to construct any bridge across any stream at a point where the same is navigable for boats or vessels of 15 tons burden or more, they shall apply to the board of supervisors by petition, and shall give notice of the same in like manner, as near as may be, as provided in section 22 of this act; and the powers and the mode of proceeding of such board, shall be the same, as near as may be, as provided in the last named section. Every such petition shall set forth the kind and description of the bridge proposed to be constructed, and whether the same is to be constructed with a draw, or whether any and what provision is to be made for the passage of vessels or boats; and such board shall have the power to grant or refuse the prayer of such petition, upon such terms as they may deem just and reasonable, and to prescribe what description of bridge may be constructed, or to prohibit the construction of any bridge on the proposed location, as in their judgment the public interest shall require.
