Dear Mr. Mettler:

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: SafetyWall
Type of system:

Longitudinal Channelizer

Test Level:

MASH Test Level 3

Testing conducted by: Transportation Research Center
Date of request: January 11, 2012
Date initially acknowledged: April 12, 2012

Decision:
The following device is eligible, with details provided below and in the drawings which are enclosed as an integral part of this letter:

Based 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 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
To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test and evaluation criteria contained in the American Association of State Highway and Transportation Officials’ Manual for Assessing Safety Hardware (MASH).

Description
The Plastic Safety Systems Inc. SafetyWall is a longitudinal channelizer formed from high density polyethylene plastic.  The crash tested longitudinal channelizer was 201 feet long fabricated from 34 individual inter-connected channelizing devices.  Drawings of the individual units are enclosed for reference.  The SafetyWall longitudinal channelizer was positioned such that the right front corner of the impacting vehicles struck the longitudinal channelizer at the center of channelizing device number 8 in both MASH tests 3-10 and 3-11.

Each individual channelizing device was secured with two (2) 45-pound sand bags.    Each individual channelizing device is equipped with two legs.  One (1) 45-pound sand bag was placed on each leg per the manufacturer installation instructions.  Type AC lights were mounted on channelizers  number 6 through 17 and sign panels were mounted to the face of the longitudinal channelizers in the impact zone. The lights and sign panels remained affixed to the channelizer units during the impacts.  Summary pages of the crash tests are enclosed.

Summary and Standard Provisions
Therefore, the system described above and detailed in the enclosed drawings is eligible for reimbursement and may be installed under the range of conditions tested.  Individual units may also be used as stand-alone barricades when affixed with the appropriate retroreflective sheeting per Section 6F of the Manual on Uniform Traffic Control Devices.

Please note the following standard provisions that apply to FHWA eligibility letters:

Sincerely yours,
