Control sections provide a convenient and reliable linear referencing method for locating features along a roadway. Control sections generally do not move or change, regardless of changes to the route name or number.

Reading Control Section Numbers

• A control section number consists of six digits (e.g. 0115-02).
• The first four digits are the control number and can range from 0001-9999.
• The last two digits are the section number and can range from 01-99.
