Dear Mr. Paulkcnberry: 

This letter is in response 10 your July 20. 20 15 request for the Federal Highway Administration 

(FH \VA) to review a roadside safety device. hardware, or system fo r eligibility for 

reimbursement under the Federal-aid highway program. This FHW/\ letter of eligibility is 

assigned Fl 1\VA control number CC-928 and is valid until a subsequent letter is issued by 

Fl I\\IA that expressly references this device. 

Decision 

The following devices arc eligible, with details provided in the form which is attached as an 

integral pan of this letter: 

Modified Gibraltar Dri ven Cable Terminal 

Scope of this Letter 

To be found eligible for Federal-aid funding, modified roadside saf'cty devices should meet the 

crash test and evaluation criteria contained in the National Cooperati ve 1lighway Research 

Program (NCHRP) Report 350. However, the rHWA, the Department of Transportation. and the 

United States Government do not regulate the manufacture of roadside safety devices. Eligibi lity 

for reimbursement under the Federal-aid highway program does not establish approval. 

ccrti fication or endorsement of the device for any particular purpose or use. 

This letter is not a determination by the FHW /\, 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 arc required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crashworthincss of the system and docs not cover other 

structural features, nor conformity with the Manual on Unifonn Traffic Control Devices. 
2 

Eligibility for Reimbursement 

FH~A 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:

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 ofany crash testing, and/or drawings ofthe device, are described in the attached 

form. 

Notice 

Ifa manufacturer makes any modification to any oftheir roadside safety hardware that has an 

existing eligibility letter from FHWA, the manufacturer must notify FHWA ofsuch modification 

with a request for continued eligibility for reimbursement. The notice of all modifications to a 

device must be accompanied by: 

o 	 Significant modifications - For these modifications, crash test results must be 

submitted with accompanying documentation and videos. 

o 	 Non-signification modifications - For these modifications, a statement from the 

crash test laboratory on the potential effect ofthe modification on the ability of 

the device to meet the relevant crash test criteria. 
3 

You arc expcc1ed to supply potential users with sufficient information on design, insta ll ation and 

maintenance requirements to ensure proper performance. 

You arc 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 NCH RP 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 submiUcd by you are accurate 

and correct. We reserve the right to modify or revoke thjs letter if: (1) there are any inaccuracies 

in the infomrntion 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 \\as issued in error or otherwise docs not rel1cct full and 

complete information about the crashworthincss of the system. 

Standard Provisions 

• 	 To prevent misunderstanding by others. this letter of eligibility designated as f l l\VA 

control number CC-9213 shall not be reproduced except in full. This letter and the test 

documentation upon which it is based arc public in formation. All such letters and 

documentation may be reviewed upon request. 

• 	 This Jetter shal l not be construed as authori?alion or consent by the FHW A to use. 

manufacture, or sell any patcmcd sys1cm for which the applicant is not the patent holder. 

• 	 Irthe subject device is a patented product il may be considered to be proprietary. If 

proprietary systems arc specified by a highway agency for use on Federal-aid projects: 

(a) they must be supplied through competitive bidding with equally suitable unpatentcd 

items; (b) the highway agency must certify that they are essential for synchroni zation 

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, Scc1ion 635.4 I I.

PRODUCT DESCRIPTION 

New Hardware or 

Significant Modification 

Modification to 

Existing Hardware Non-Significant 

Gibraltar Cable Barrier Driven I-Beam End Terminal - This request is to modify the original end terminal design 

to use a multiple I-Beam driven post foundation instead of the original concrete foundation design. Original 

design was with concrete foundations, as presented in FHWA eligibility letter CC-92. (Original system drawing 

included with submission for comparison purposes.) FHWA eligibility letter CC-92A addressed modifications in 

the original foundation design; the modification of the system involves replacing the one 8"x8"x3/8"x8' anchor 

tube and four 3"x4"x3/16" tube sockets connected by a 2"x4"x3/8" angle iron ground struts with three W8x31x8' 

sections connected with dual C6x13 ground struts. The resulting system is significantly stiffer and not expected 

to alter the impact performance of the system. Engineering design calculations prepared by G2 Engineering 

Consulting Group for a static design load deflection of not more than 1-inch movement in AASHTO Standard 

soil has been submitted and reviewed by Karco Engineering and determined that the steel driven I-Beam 

terminal foundation design uses multiple 8" I-Beams to make it stronger than the single 8"x8" steel tube design 

in poorer soils. All changes were underground; no above ground items were modified and does not effect the 

crashworthiness of the end terminal design.
