AASHTO is the author of two documents that have guided utility accommodation highways for decades. The first document primarily applies to utility accommodation on highways that are part of the Federal Aid system. The second document primarily applies to utilities on state highways.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 356: Development of a Guide for Accommodating Utilities within Highways and Freeways details changes in these rules and regulations over the years and ways AASHTO guidance can continue to evolve.

Supplemental to the document is a presentation.
