When property that is devoted to or held for another public use for which the power of eminent domain may be exercised is taken for highway purposes, the department may, with the consent of the person or agency in charge of the other public use, condemn real property to be exchanged with such person or agency for the real property so taken. This section does not limit the authorization of the department to acquire, other than by condemnation, property for that purpose in any other manner.
