FDOT Standard Plans Index 700-041: Span Sign Structure
Short answer
Index 700-041 is the FDOT Standard Plan for Span Sign Structure, 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 Criteria
Design Criteria AASHTO LRFD Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals (LRFDLTS) ; Structures Manual (SM) , Volume 3, FDOT Modifications to LRFDLTS; Structures Manual (SM) Introduction, I.6
References

Design Assumptions and Limitations
Design Assumptions and Limitations The maximum span length of Span Sign Structures is 220 feet. See the notes on Index 700-041 , FDM 230 , FDM 261 , Structures Manual (SM) , Volume 3 and the SDG for additional information. Use Index 700-041 in conjunction with Index 700-030 and the Span Overhead Sign Mathcad 15 computer program located on the Structures Design Programs Library website.
Consider fabrication constraints when reviewing shop drawings. Mill lengths for large tubes (uprights and truss chords) are limited to 35 to 40 feet lengths; therefore, the general fabrication limits noted on Index 700-041 may not be feasible for larger structures. The following required exceptions have been noted: • The “three truss panel lengths” minimum cannot be met when panel lengths exceed 10 feet.
Fabricator should minimize the number of splices by maximizing mill lengths. • When the upright post exceeds mill lengths, a complete penetration weld is allowed in the top of the upright, but not within 12 inches of the truss support welds.

How PDFDepth uses this index
When a plan set cites Index 700-041, PDFDepth's AI Plan Review cross-references the set against the Plan Content Requirements for the FDOT indexes it cites and flags items that appear to be missing — each with a citation to the sheet. A human reviewer verifies every flag before it counts.
