Instructional Memorandums

The IMs provide assistance to LPAs on a wide variety of transportation-related topics. Some IMs supplement the Guide by providing more detailed information or instructions that are applicable to federal-aid transportation projects. Other IMs are applicable to state or locally funded projects. Still others are applicable to all types of projects. If the applicability of an IM is limited by funding or other considerations, this is explained in the "Contents" section at the beginning of the IM.
