FDOT Standard Plans Index 700-120: Enhanced Highway Signing Assembly
Short answer
Index 700-120 is the FDOT Standard Plan for Enhanced Highway Signing Assembly, part of Series 700 (Signing, Pavement Markings and Lighting). The sections below are extracted from FDOT's Standard Plans Instructions (SPI) for this index — design criteria, assumptions and limitations, and what your plans must show.
Design Assumptions and Limitations
Design Assumptions and Limitations The designs shown in Index 700-120 are based on systems crash tested for compliance with the AASHTO Manual for Assessing Safety Hardware ( MASH ). Modifications to these designs may significantly affect the crashworthiness of the system and should not be done without consultation with the State Roadway Design Office. Except for an Overhead Sign Assembly, an Alpha-Numeric identification scheme is provided in Index 700-120 for the “Type” designation of the selected roadside Enhanced Highway Signing Assembly.
These are provided to facilitate ease of callouts in the Plans. Base the Alpha-Numeric designation on a combination of the selected “Power Configuration” type and the “Roadside Sign Assembly” number (e.g., Type A1), as follows: • Power Configuration: o Conventionally-Powered Configuration ‘A’ o Solar-Powered Configuration ‘B’ • Roadside Sign Assembly: o Warning Sign w/Flashing Beacon Assembly ‘1’ o School Zone w/Flashing Beacon Assembly ‘2’ o School Zone w/Speed Feedback & Flashing Beacon Assembly ‘3’ o Speed Limit w/Speed Feedback & Flashing Beacon Assembly ‘4’ o Wrong Way w/ Highlighted Sign Assembly ‘5’ o Blank Out Sign Assembly ‘6’ o Railroad Crossing w/ Flashing Beacon Assembly ‘7’ o Railroad Sign w/ Highlighted Sign Assembly '8’ o Railroad Yield or Stop w/ Highlighted Sign Assembly ‘9’ Index 700 - 1 20 Enhanced Highway Signing Assembly

What your plans must show
Plan Content Requirements for this index — the SPI's checklist for designers.
- Identify and tabulate in the Signing and Pavement Marking Plans. For Roadside Sign Assemblies, include the Alpha-Numeric “Type” identification in the signing callout label (e.g., Enhanced Highway Signing Assembly, Type A1). See FDM 940 plan content requirements. For spread footing, show base location in the Plans. Base location can vary throughout the spread footing but must be at a minimum of 1 ⅝ ” from the edge of the spread footing. Anchor bolts within the base and the spread footing must be at a minimum of 6” from the edge of the spread footing.
