Is there a more current version of the Guide to Standardized Highway Barrier Hardware?  The on-line version is from 1995 and AASHTO list 1995 as the publishing date for the paper version of the guide. 

I know that MwRSF has submitted items to be place into the guide, and they have been approved.  However, I don't know if someone has been keeping the on-line version up to date or if a updated paper copy exist elsewhere.

The 1995 AASHTO Hardware Guide is the latest in print. However, AASHTO Task Force 13 has been updating the CAD details for new components over the last several years. Old or existing parts are receiving little to no attention. Yes, MwRSF has been providing new CAD details for those roadside safety developments and components that were generated over a prior period through a prior Pooled Fund project. However, that effort is nearing completion and will need to be renewed if that effort is to continue. There is a web location where these details are being housed and where comments are added for consideration. The proboards site is as follows:

Also, the final electronic CAD details will eventually be located on a TTI FTP site. That site is as follows:
