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.
Maintenance Memos were drafted between 1977 and 2007. Maintenance Memo 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 Maintenance Memo and Maintenance Advisory, the information in the most recent document should prevail.
