In many jurisdictions in the US, roads were run along every section line, giving access to previously remote areas and serving in many instances as firebreaks. A road or arterial in which the centerline is laid out along a section line boundary is often referred to as a section line road or section line arterial. In Lubbock, Texas, Oklahoma City; Boise, Idaho; metropolitan areas of Arizona (most notably Phoenix and Tucson); and much of the Las Vegas Valley, all major thoroughfares run along section lines, producing a readily identifiable grid.
In some locales, section lines were designated as the basis for the street numbering system.
