Abstract

The Oregon State Highway Division has many aids which help highway personnel determine what physical features are present at any location on the more than 7,500 miles of State Highways in Oregon. These aids include as-constructed plans, county maps, right-of-way maps, aerial photographs, mile point logs and straight line charts. The latter, straight line charts, have been prepared for all State Highways and are referenced by a mile-posting system. These charts show such features as structures, pavement type, city limits, and intersecting roads by mile point.
