The Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD), Arizona Department of Transportation, and the U.S. Forest Service developed a comprehensive Geographic Information Systems (GIS) Inventory of all roadway features along the historically significant State Route 88 Corridor, also known as the Apache Trail, in Arizona's Tonto National Forest. The GIS Inventory documents the 850 roadway features along the Apache Trail, allowing the partner agencies to identify the exact location of specific roadway features like culverts and retaining walls. This helps expedite the environmental review process, by organizing roadway information and making it readily accessible to environmental practitioners.

The Inventory provides a summary of the many roadway components and tracks the conditions of these features, helping staff prioritize rehabilitation projects. The tool allows FHWA-CFLHD and its partners, including the Arizona Department of Transportation and the U.S. Forest Service, to quickly identify roadway features and determine appropriate maintenance treatments or other actions. FHWA-CFLHD's GIS Inventory can act as a template for other historically significant roadways within Arizona and other parts of the country facing similar challenges.
