Since 1982, the atlas has provided long-haul operators with proprietary routing data, including hazardous material regulations, low-clearance warnings, and weigh station locations. Beyond standard mapping, the publication includes a 22-page directory detailing over 40,000 city-to-city mileages tailored for commercial vehicle routes.

The 2027 edition incorporates significant infrastructure changes across North America, ranging from the completed Fayetteville Outer Loop in North Carolina to new interstate designations in Oklahoma and Connecticut. Notably, the update tracks the conversion of U.S. Highway 15 to Interstate 99 in Pennsylvania and the expansion of U.S. Highway 395 in California. The atlas is available in various formats, including a laminated spiral-bound edition and a large-scale version with 37% larger print, through travel centers and the company’s website.
