The South Dakota Department of Transportation Standard Plates are available only in U.S. Customary units. Drawings are not always drawn to scale; use the dimensions on the drawings for correct measurements. Every effort has been made to assure their correctness. If there are any discrepancies between these standard plates and other contract documents, section 5.4 Coordination of Plans, Specifications, Supplemental Specifications, and Special Provisions of the 2004 Standard Specifications for Roads and Bridges governs.
If you have comments or wish to make changes to a standard plate, please make a copy of the standard plate showing your revisions and send it to:
