GENERAL NOTES
1. The illustrations for guardrail applications are standard configurations; adjustments are to be made as required by site specific
conditions to attain optimum design for function, economy and serviceability.
10. The W-beam guardrail system in this index is the standard system to be used on the State Highway System where a Test Level
3 semi-rigid barrier is required.
2. The beginning of guardrail need shall be at the greatest of the upstream distances from the hazard, as determined from Figures 1
and 2, and other application details of this Index.
11. Thrie-beam guardrail panels shall be used in guardrail transitions to bridge traffic railing barriers, to concrete and certain
water filled safety shaped barriers, certain crash cushions and as a continuous barrier when called for in the plans. For
additional information on rail attachment, post spacings, nested rails, location of thrie-beam transition panels and offset block
3. One Panel (i.e., panel length) equals 12’-6". Guardrail shall be constructed with rail elements 12’-6" in length except where 25’-0"
elements are called for by this and other standards (indexes) or specifically called for in the plans.
configurations see details elsewhere in this Index, and Index Nos. 402, 410 and 414. The use of thrie-beam guardrail with
standard offset blocks (Test Level 3 semi-rigid system) may be considered where one or more of the conditions listed below or
similar conditions are anticipated or exist:
Post spacing shall be 6’-3" except that reduced spacing shall be used for (a) transitions to anchorages at rigid structures such as
bridges (See Detail J and Index No. 402 ) and transitions to redirective crash cushions, (b) the conditions in Note No. 7 below, (c)

4. Guardrail mounting height for the W-beam without rub rail and for thrie-beam is 1’-9" to the center of beam, and for W-beam with
surface irregularities (e.g., across shoulder gutters, inlets and roadway surface break lines). For guardrail placed on slopes beyond

approach ends. Parallel end anchorage assemblies for guardrail approach end treatments will be constructed only when restraints

Wide medians where approach end anchor is located outside of opposing roadway clear zone,

Index drawings, or QPL drawings if applicable.
13. Straight rail sections may be used to construct radii of 125’ or greater. For radii less than 125’ the rail must be fabricated
(shop-bent) to fit.
If the plans call for end anchorage assembly "parallel" and does not identify the specific system(s) to be used, the contractor has
the option to construct any FDOT approved parallel assembly provided in this Index or identified on the QPL, subject to the
conditions identified in the approved Index drawings, or QPL drawings if applicable.
14. Crash cushions may be required in lieu of or in conjunction with guardrail at locations where space does not permit development
of sufficient guardrail length, offset or crashworthiness at terminals. Crash cushions shall be constructed at or in lieu of Type

If the plans call for a specific end anchorage assembly, substitutions with other end anchorage assemblies will not be permitted
unless approved by the Engineer. Approved substitutions will not be eligible for CSIP consideration.

diagram applies to other configurations that may occur at the beginning of length of need,
such as, other flare designs; upstream returns; and, other upstream deflected, tangent and
curvilinear conditions.
Equation Variables:
D = Distance in feet from near edge of the near approach traffic lane to either (a) the back of
hazard, when the hazard is located inside the clear zone or horizontal clearance or (b) the clear
zone or horizontal clearance outer limit, when the hazard extends to or goes beyond the clear zone
or horizontal clearance limit. For left side hazards on two-way undivided facilities, D is measured
from the inside edge of the near approach traffic lane (see Figure 2).
d = Distance in feet from the near edge of the near approach traffic lane to the face of guardrail
at its intersection with the departure line.
For left side hazards on two-way undivided facilities,

d is measured from the inside edge of the near approach traffic lane (see Figure 2).
For flared and parallel end anchorage assemblies the beginning length of need is to be set at the
