AASHTO Criteria

An evaluation of AASHTO Controlling Design Criteria is required for all projects (See Design Exception Variance) on the National Highway System. The 2009 AASHTO Guide should be utilized for preparing the AASHTO Controlling Design Criteria Report, but should take into account the recent adoption of AASHTO’s 2011 “A Policy on Geometric Design of Highways and Streets”, AASHTO’s 2016 publication of “A policy on Design Standards – Interstate System” and FHWA’s revisions to the AASHTO Design Criteria for projects on the NHS. Projects that do not meet the AASHTO controlling criteria will require a design exception. The following documents should be reviewed when preparing an AASHTO Controlling Design Criteria Report.
