Curb Ramp Engineering

ODOT worker testing curb ramp design with wheelchair user. When curb ramps are included in a project, ODOT requires several processes to ensure the constructed curb ramp will comply with accessibility requirements. The processes are summarized in the ODOT ADA Curb Ramp Process document.
  • Design shall meet the criteria in the ADA Curb Ramp Design Checklist.
  • Design detail sheet shall be provided for each corner.
  • Constructed curb ramps must be inspected using an ODOT curb ramp inspection form to document compliance with accessibility requirements.
  • The standards for the design of curb ramps are in the Highway Design Manual. 
  • The ADA Curb Ramp Design Checklist is a companion aid for design.
