June 2012 Errata to AASHTO LRFD Bridge Design Specifications, Customary U.S. Units, 6th Edition. It records the corrections adopted by AASHTO after the parent document was published, listing the revised text and replacement pages so that printed and downloaded copies can be brought up to date. The sheet is used together with the parent specification by designers, contractors and agency staff who need to work from the current official wording.
