Motorcyclist Airlifted After Serious Crash on US 20 Near St. Anthony

ST. ANTHONY, Idaho (Day.News) — Emergency crews airlifted a motorcyclist to a local hospital following a serious crash on U.S. Highway 20 near St. Anthony Saturday around 1 p.m.[1] Fremont County Sheriff Bart Quayle confirmed the incident to East Idaho News, noting that as of 3:30 p.m., deputies were actively investigating and details remained limited.[1] The biker's gender and current condition were unknown at the time, but the severity required air ambulance transport.[1] Traffic backed up temporarily on the highway while responders worked the scene, but U.S. 20 has since reopened with normal flow restored.[1] The stretch near St. Anthony, a gateway to popular spots like the St. Anthony Sand Dunes, sees heavy recreational traffic, especially on weekends.[1][2] This crash follows a pattern of motorcycle incidents in Fremont County, including a fatal dune crash last year where a rider plummeted 50 feet onto lava rocks.[2][3] Sheriff Quayle emphasized caution for riders on area roads and dunes, where terrain shifts seasonally and high speeds amplify risks.[1][4] No other vehicles were reported involved, and the investigation continues to determine the cause.[1] Local officials urge helmets, flags on dune bikes and awareness of changing conditions amid peak riding season.[4]
