The Florida Department of Transportation has revised the Florida Intersection Design Guide (FIDG) to provide designers with a handbook, to be used as guidance, for new construction and major reconstruction of at-grade intersections on the State Highway System.


The information contained in the FIDG is based on the Plans Preparation Manual, Design Standards, MUTCD, and other referenced documents. If there is a conflict between the FIDG and any approved/adopted criteria or standards, then the approved/adopted criteria or standards shall govern.



All FIDG users must register their e-mail addresses in this contact database, and select the Florida Intersection Design Guide as an area of interest in order to receive future update notices, design memos, or other important information concerning the Department's design manuals used.  Users can register at the following link:




If you should have any questions, comments or suggestions regarding the FIDG, you can contact any of the following individuals:
