CalTrans Amber Alert Sign Specifications


Midwest Guardrail System (MGS)

CATEGORY: Design (The following information is based on the current North Dakota Department of Transportation (NDDOT) Standard Drawings as well as recent research results).

ISSUE: Standard strong-post W-beam, referred to in North Dakota as “w-beam guardrail 2

8 inch” , or “G4” , has been one of the most widely used traffic barriers in the United States. Recent testing with today’s high center of gravity vehicles however has shown it to be near or at its performance limits in high speed, high angle roadside crashes. A new nonproprietary design, the Midwest Guardrail System (MGS) has been successfully crash-tested, both under NCHRP 350 and MASH at Test Level 3 (TL-3), and has been adopted by NDDOT as their standard w-beam system.


OBJECTIVE: To provide information on the MGS and some of its design flexibility to NDDOT design engineers and other personnel who may have responsibilities for designing, installing, inspecting, or maintaining this design. NDDOT’s current detailed drawings for the MGS system were originally adopted in 2017; this system is in compliance with the AASHTO/ FHWA Agreement for MASH implementation.


METHODOLOGY: This Technical Brief will describe the MGS characteristics and identify the types of locations for which variations of the design have been successfully crash-tested. For additional information please see the FHWA website.
