Dear Mr. Stephens:
This letter is in response to your request for  the Federal Highway Administration (FHWA) to review a roadside safety system  for eligibility for reimbursement under the Federal-aid highway program.

Name of system:
Modified Thrie Beam BlockoutType of system:
  Longitudinal BarrierTest Level:
NCHRP Report 350, TL4Testing conducted by:
Texas A&M Transportation InstituteTask Force 13 Designator:
PWB03Date of request:
  November 8, 2013Date of completed package:
  November 30, 2013**Decision:**
  The following device is eligible, with details provided in the form which is attached  as an integral part of this letter:
Modified  Thrie Beam BlockoutBased on a review of crash test results submitted by the  manufacturer certifying the device described herein meets the crash test and  evaluation criteria of the National Cooperative Highway Research Program  (NCHRP) Report 350, the device is eligible for reimbursement under the  Federal-aid highway program. Eligibility  for reimbursement under the Federal-aid highway program does not establish  approval or endorsement by the FHWA for any particular purpose or use.
The FHWA, the Department of Transportation, and the United  States Government do not endorse products or services and the issuance of a  reimbursement eligibility letter is not an endorsement of any product or  service.
**Requirements**
  To be found eligible for Federal-aid funding, roadside  safety devices should meet the crash test and evaluation criteria contained in  the National Cooperative Highway Research Program (NCHRP) Report 350 or the  American Association of State Highway and Transportation Officials' Manual for  Assessing Safety Hardware (MASH).
**Description**
  The device and supporting documentation are described in  the attached form.
**Summary and Standard Provisions**
  Therefore, the system described and detailed in the  attached form is eligible for reimbursement and may be installed under the  range of conditions tested. Please note  the following standard provisions that apply to FHWA eligibility letters:
This letter provides a AASHTO/ARTBA/AGC  Task Force 13 designator that should be used for the purpose of the creation of  a new and/or the update of existing Task Force 13 drawing for posting on the  on-line 'Guide to Standardized Highway Barrier Hardware' currently referenced  in AASHTO Roadside Design Guide.
  This finding of eligibility does not  cover other structural features of the systems, nor conformity with the Manual  on Uniform Traffic Control Devices.
  Any changes that may influence system  conformance with NCHRP Report 350 criteria will require a new reimbursement  eligibility letter.
  Should the FHWA discover that the  qualification testing was flawed, that in-service performance reveals safety  problems, or that the system is significantly different from the version that  was crash tested, we reserve the right to modify or revoke this letter.
  You are expected to supply potential  users with sufficient information on design and installation 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 crash test and evaluation criteria of the NCHRP Report 350.
  To prevent misunderstanding by others,  this letter of eligibility is designated as number B-248 and 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 at our office 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. The FHWA does not become involved in issues  concerning patent law. Patent issues, if any, are to be resolved by the  applicant.
  Because it is a steel product, the Modified  Thrie Beam Blockout is subject to Section 635.410 (Buy America) of Title 23,  U.S. Code of Federal Regulations, and cannot be permanently incorporated into  any federally funded project unless it is made in the U.S. from U.S. steel.Sincerely yours,
			Signature Michael S. Griffith
