Maintenance advisories
Maintenance advisories (MA) provide information and guidance in performing maintenance activities on state trunklines to regions, TSCs, garages, special crews, and local agencies.
They are meant to promote uniformity in interpretation and application of maintenance practices statewide.
MAs have been used since 2005. Maintenance memos (MM) were used to convey information and updates on maintenance practices from 1977 to 2007.
If there is conflicting information between a published MM and MA, the information in the most recent document should prevail.
