Part I: Guidelines for the Selection of Supplemental Guide Signs for Traffic Generators Adjacent to Freeways Part II: Guidelines for Airport Guide Signing Part III: List of Control Cities for Use in Guide Signs on Interstate Highways (Revision 4)
Foreword: The Manual on Uniform TrMc Control Devices for Streets and Highways (MUTCD) discusses in Sections 2E-28 and 2F-20 the use of Supplemental Guide Signs to provide motorist information regarding destinations accessible from an interchange@ other than places shown on the standard interchange signing. The guidelines outlined in Part I of this document are intended to provide a basis for development of individual state policies for the selection of supplemental guide signs for traffic generators adjacent to freeways. These policies should consider local needs@ customs@ and legal requirements. Earlier editions of Part I included supplemental guide signing for airports adjacent to freeways. In response to the AASHTO Standing Committee on Aviation's request@ these airport guidelines were expanded to include all highways. Part II contains the new guidelines for supplemental guide signs for airports. Sections 2D-37@2E-33@ and 2F-7 of the MUTCD make reference to the use of control cities which have national significance. Part III of this document contains the list of approved control cities for purposes of providing directional guidance on the Interstate Highway System.
