FLH Standard Drawings

FLH Standard Drawings are intended to cover various design elements and be applicable nationwide.  Each standard drawing is available in both Metric and US Customary units and conforms with the Standard Specifications (FP).  See the Revision Log  (Acrobat, 111 KB) for description of most recent approved changes.  If you have any questions or comments concerning these standard drawings please contact the Project Development Team.

The drawings are available in Acrobat (PDF) and MicroStation (DGN) formats.  Individual PDF files are available for both US Customary and Metric units.  The single DGN file contains both US Customary and Metric Standard Drawings.  Obtain the desired units by selecting either the 'USC' (US Customary) or 'Metric' View or Model (from the menu File -> Models).

Note:  Some older drawings contain sheet borders for each FLH division.  These will be phased out in preference to a standardized sheet.

Select desired DGN and/or PDF files using the check boxes below.  Use the button to create a ZIP.  Reload page to clear boxes.
