Highway Index Maps

The Statewide Highway Index Map series illustrates the location of inventoried roadways and the administrative inventory route numbers assigned to those roads by the Maryland State Highway Administration (SHA). These maps contain many of the same features as the Grid Maps,and are at a scale of 1:12,000.

The Highway Index Maps are updated annually and available as PDF files. To view, print or download PDF files, you must have Adobe Reader installed on your computer.
