Dear Mr. Dyke:
            This letter is in response to your December 23, 2015 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 B-69E 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:
            Concrete Reactive Tension System (CRTS) and Steel Reactive  Tension System (SRTS) modifications***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:
                  Concrete Reactive Tension System (CRTS) and Steel Reactive Tension System (SRTS) modificationsDate of original request:
                  December 23, 2015Original FHWA letter:
                  B-69 dated June 27, 2000FHWA Control number:
                  B-69E
            The pending modification(s) consists of the following  changes:
1) Reduce diameter of bolt hole  in base plate for rubber foot attachment
2) Stronger pin retaining clip
3) Modified spring pusher plate
4) More durable hydraulic breather  cap
            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 B-69E 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,
