Guardrail Requirement

Guardrail Requirement

(OP)
Hi all,
I'm designing a concrete floodway/causeway over a box culvert. At the moment there is no guardrail on the culvert or approaches. Where can I find the exact guardrail requirement in this situation ? The site is in Queensland .

Thank you.

RE: Guardrail Requirement

I would advise you check out your local roadside safety manual. For roads, it's a combination of the severity of the sideslopes, vehicle speed, etc.

This won't be physically useful to you since it won't match your locales requirements, but the State of Illinois details how to design guardrail lengths in this manual: http://www.idot.illinois.gov/assets/uploads/files/...

Hope this helps get you on the right track.

Hi Ashtree,
Are you referring to specific part in MUTCD or is it general reference ?

Thank you.

RE: Guardrail Requirement

That is a general reference only. However i i believe there is a specific section regarding guardrailing.

Regards
Ashtree
