Design Details available for Guardrail/Barrier design

Design Details are drawing details provided for use in plan preparation, but are not issued or supported as a MnDOT Standard.  The design engineer of record is responsible for taking full ownership and responsibility for the use of detail as is, or as modified. 

Each Design Detail can be used separately through inclusion into another plan sheet or as its own sheet. In either case, a registered engineer must sign the sheet (exception: Proprietary Product Sheets).

These drawings are available to MnDOT designers in MicroStation format.   Non-MnDOT designers can request a design detail in MicroStation format from the MnDOT Project Manager/Engineer.
