County Maintained Roads
Multnomah County Road Maintenance is responsible for maintaining 274 miles of roads, as specified in the Master Road List. County roads are divided into sections. The beginning and end of each section have mile points (MP). Please take note of the “From Location/To Location” column of the Master Road List. This column specifies the descriptions of beginning and end mile points of each section. The column at the far right indicates the Pavement Condition Index (PCI) for each section. PCI is explained in the Pavement Management Program.
