Any 2 adjoining cities or villages, or an adjoining city and village, may, by a 3/5 vote of their several legislative bodies, unite in making and maintaining any public improvement located on or near the boundary line between such municipalities and located either entirely within 1 or partly within each of such municipalities, and may agree upon the method and manner of making and maintaining such improvement, the division of the cost thereof, and all other matters connected therewith. In no case, however, shall any municipality pay a greater proportion of the cost of any such improvement than its legislative body shall by a 3/5 vote determine such municipality is benefited thereby. Such municipalities shall have authority in their joint names to condemn property necessary for any such improvement and for such purpose may bring proceedings under Act No. 149 of the Public Acts of this state of 1911 or under any other general law of this state in relation to the condemnation of property for public purposes. If the property to be taken is located entirely within 1 such municipality, condemnation proceedings may be taken jointly or by the municipality in which such property is located.
