Oregon Revised Statutes Highways, Roads, Bridges and Ferries § 366.325

The Department of Transportation may acquire by purchase, agreement, donation or by exercise of the power of eminent domain, real property for right of way through a cemetery, except that the department has no authority to acquire any such real property by exercise of the power of eminent domain if within the area sought to be taken there are graves which would be disturbed by the location and construction of a highway. The department may acquire by purchase, agreement, donation or exercise of the power of eminent domain, real property contiguous to the cemetery, and may convey such real property to the cemetery association or the owners of the cemetery in exchange for the property sought to be acquired for right of way purposes, but such authority shall not be exercised unless and until the owners of the cemetery agree in writing to the exchange of lands.
