Dear Mr. Rosenbaugh:

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:

Midwest Guardrail System with White Pine Posts

Type of system: 31 inch high W-beam guardrail
Test Level: MASH Test Level 3
Testing conducted by: Midwest Roadside Safety Facility
Task Force 13 Designator: SGR20c
Date of request: June 28, 2011
Date initially acknowledged:

July 18, 2011

Date of completed package:

June 28, 2011

Decision:
The following device is eligible, with details provided in your June 28, 2011, letter which is enclosed and considered an integral part of this finding:

Based on a review of crash test results you submitted certifying the device described herein meets the crashworthiness criteria of the American Association of State Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH), 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
Roadside safety devices should meet the guidelines contained in the MASH.

Description and Crash Testing
The MGS with White Pine Posts is described in the enclosed letter dated June 28, 2011 and is illustrated in the enclosed drawings.  The MASH Test 3-11 is detailed in the enclosed Test Data Summary Sheet and showed that the pickup truck test met all appropriate criteria. The maximum dynamic deflection of the barrier was 46.3 inches, and the Working Width of the system was 58.4 inches. In comparison, the Working Width of the MGS on Southern Yellow Pine posts was 49 inches.

Findings
Therefore, the system described and detailed in the enclosures 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:

 

Sincerely yours,
