The highway segment designations implement Policy 1B, the land use and transportation policy of the Highway Plan. Highway segment designations include Special Transportation Areas (STAs), Urban Business Areas (UBAs), and Commercial Centers (CCs). Highway segment designations may change the applicable Oregon ODOT design standards, mobility standards and access management spacing standards within the segment.
Individual segments can be found below by Region. See the Registry of Amendments for more information on actions by the OTC to designate highway segments.
