Hi all,

Can any of you transportation/highway design guys/gals help me out? I need to know if there's a TL rating for a typical single w-beam metal guardrail with strongposts at 75" on center. I looked through all the AASHTO Roadside Design Guide and other references and couldn't find anything (maybe I overlooked it?).

Anyway, I'm a structural guy so I have no clue. Wondering why I need to know? Well, it's a long story, but any help would be greatly appreciated.

Thanks in advance...
