Where the State Highway 77 numbers come from

Counted from NHTSA's Fatality Analysis Reporting System, 2024 Annual Report File: every fatal crash whose road NHTSA filed as State Highway 77 in Arizona (filed under 6 spellings, such as "SR-77", "SR-77 E CUESTA ST", "SR-77 MIRACLE MILE", "SR-77 N ORACLE RD"). Ramps, frontage and service roads are left out. Where two routes share a road, NHTSA files each crash under one of them, so a shared stretch counts on one route only. A fatal crash is one in which someone died within 30 days. Totals in state and news reports for a road usually differ: they include ramps and frontage roads, or count from preliminary reports.
