Dear  Mr. Stephens:
            This letter is in response to your July 22, 2014 request  for the Federal Highway Administration (FHWA) to review a roadside safety  device, hardware, or system for eligibility for reimbursement under the  Federal-aid highway program. This FHWA  letter of eligibility is assigned FHWA control number HSST/CC-124 and is valid  until a subsequent letter is issued by FHWA that expressly references this  device.
            ***Decision***
      The following devices are eligible, with details provided  in the form which is attached as an integral part of this letter:
              Trinity Slotted Rail Terminal SRT End Terminal Family  Ground Strut Modification***Scope of this  Letter***
            To be found eligible for Federal-aid funding, modified  roadside safety devices should meet the crash test and evaluation criteria  contained in the National Cooperative Highway Research Program (NCHRP) Report  350. However, the FHWA, the Department of Transportation, and the United States  Government do not regulate the manufacture of roadside safety devices.  Eligibility for reimbursement under the Federal-aid highway program does not  establish approval, certification or endorsement of the device for any  particular purpose or use.
      This letter is not  a determination by the FHWA, the Department of Transportation, or the  United States Government that a vehicle  crash involving the device will result in any particular outcome, nor is it a  guarantee of the in-service performance of this device. Proper manufacturing,  installation, and maintenance are required in order for this device to function  as tested.
            This finding of eligibility is limited to the  crashworthiness of the system and does not cover other structural features, nor  conformity with the Manual on Uniform Traffic Control Devices.
            ***Eligibility for  Reimbursement***
            FHWA previously issued an eligibility letter for the  roadside safety system described in your pending request. Your pending request  now identifies a modification to that roadside safety system.
      The original roadside safety device information is provided  here:
      Name of  system:
               	  Slotted Rail Terminal (SRT)Type of  system:
               	  TerminalDate  of original request:
               	  November 6, 1995Date  of original FHWA eligibility letter:
               	  December 4, 1995FHWA  Control number:
               	  CC-31          
            Name of  system:
                Modified Slotted Rail Terminal (SRT)Type of  system:
                TerminalDate  of original request:
                November 21, 2000Date  of original FHWA eligibility letter:
                December 18, 2000FHWA  Control number:
                HSA-1/CC72The pending  modification(s) consists of the following changes:
            Allow the single 3"×3"×1⁄4"  angle ground strut as a satisfactory replacement for the older SRT strut  configurations (i.e., CC-31 & CC-72) and consider it acceptable for use in  all versions of the Slotted Rail Terminal (SRT).FHWA concurs with  the recommendation of the accredited crash testing laboratory as stated within  the attached form.
            ***Full Description  of the Eligible Device***
            The device and supporting documentation, including reports  of the crash tests or other testing done, videos of any crash testing, and/or  drawings of the device, are described in the attached form.
            ***Notice***
            If a manufacturer makes any modification to any of their  roadside safety hardware that has an existing eligibility letter from FHWA, the  manufacturer must notify FHWA of such modification with a request for continued  eligibility for reimbursement. The  notice of all modifications to a device must be accompanied by:
      Significant modifications – For these modifications, crash test results must be submitted with        accompanying documentation and videos.
                Non-signification        modifications – For these modifications, a statement from the crash test        laboratory on the potential effect of the modification on the ability of        the device to meet the relevant crash test criteria.FHWA's determination of continued eligibility for the  modified hardware will be based on whether the modified hardware will continue  to meet the relevant crash test criteria.
You are expected to supply potential users with sufficient  information on design, installation and maintenance requirements to ensure  proper performance.
            You are expected to certify to potential users that the  hardware furnished has the same chemistry, mechanical properties, and geometry  as that submitted for review, and that it will meet the test and evaluation  criteria of the NCHRP Report 350.
Issuance of this letter does not convey property rights of  any sort or any exclusive privilege. This letter is based on the premise that  information and reports submitted by you are accurate and correct. We reserve  the right to modify or revoke this letter if: (1) there are any inaccuracies in  the information submitted in support of your request for this letter, (2) the  qualification testing was flawed, (3) in-service performance or other  information reveals safety problems, (4) the system is significantly different  from the version that was crash tested, or (5) any other information indicates  that the letter was issued in error or otherwise does not reflect full and  complete information about the crashworthiness of the system.
      ***Standard Provisions***
      To  prevent misunderstanding by others, this letter of eligibility designated as  FHWA control number HSST/CC-124 shall not be reproduced except in full. This letter and the test documentation upon  which it is based are public information.  All such letters and documentation may be reviewed upon request.
              This  letter shall not be construed as authorization or consent by the FHWA to use,  manufacture, or sell any patented system for which the applicant is not the  patent holder.
              If the subject device is a patented product it may be considered  to be proprietary. If proprietary  systems are specified by a highway agency for use on Federal-aid projects: (a)  they must be supplied through competitive bidding with equally suitable  unpatented items; (b) the highway agency must certify that they are essential  for synchronization with the existing highway facilities or that no equally  suitable alternative exists; or (c) they must be used for research or for a  distinctive type of construction on relatively short sections of road for  experimental purposes. Our regulations  concerning proprietary products are contained in Title 23, Code of Federal  Regulations, Section 635.411.Sincerely yours,
            Signature of George E. Rice, Jr.
