Maintenance memos
Maintenance memos (MM) provide information and guidance in performing maintenance activities on State trunklines to MDOT's regions, TSCs, garages, special crews, and local agencies.
MM were drafted between 1977 and 2007. MM information replaces the Operations Maintenance Handbook, Volume 1 - Operations.
Since 2005 maintenance advisories (MA) have been used to convey information and updates on maintenance practices.
If there is conflicting information between a published MM and MA, the information in the most recent document should prevail.
