Introduction: The Pioneer Highway’s Modern Legacy
The 560-mile route from Twin Falls, Idaho, to Gig Harbor, Washington, roughly follows the old Oregon Trail corridor, crossing the Snake River Plain and Blue Mountains before descending to Puget Sound. A little-known fact: near Glenns Ferry, Idaho, the highway crosses the exact spot where thousands of pioneers forded the Snake River in the 1840s—a crossing known as Three Island Ford. Today, Interstate 84 and US-20/US-26 trace a path that remains both historically resonant and scenically dramatic.
