What are IM's and who uses them?

Instructional Memos (IMs) are a mechanism used by the Bureau of Highways to provide information on and/or change MDOT procedures and processes. IMs are used by the bureau, consultants, local government agencies and contractors. Items are placed in this directory only after they are approved by MDOT. Signed copies are available upon request. Please contact Mary Nurenberg at nurenbergm@michigan.gov or 517-322-5667 if you have any questions.
