Design Guidance

MnDOT has officially transitioned from the Road Design Manual (RDM) to its successor, the Facility Design Guide (FDG). On December 12, 2024, two transmittal packages (FDG 24-05 and RDM 24-04) were published following approval and concurrence by FHWA on December 10, 2024. Notably, RDM 24-04 represents the final transmittal package for the RDM. With its release, all content from the RDM has been retired, reproduced, or updated within the FDG, and the RDM is now formally retired.

Historical versions of the RDM, along with associated transmittal letters, can be found in a comprehensive list available in the link below.
