Highway 140 Centennial Day: A century of connection, community and memories made along the way!
Yosemite Mariposa County Tourism Bureau staff were honored to join the Mariposa County Board of Supervisors this week as they presented a proclamation officially recognizing September 22, 2026, as Highway 140 Centennial Day.
Completed into Yosemite National Park in 1926, the historic “All-Year Highway” has connected generations of residents, businesses and visitors along the Merced River corridor, helping shape the communities and tourism economy of Mariposa County.
The centennial is more than a look back. It’s an opportunity to celebrate the people and partnerships that have shaped Highway 140, recognize the stewardship happening today, and look toward the next 100 years of community vitality, economic opportunity and care for this special corridor.
We’re grateful to the Board of Supervisors for recognizing this milestone and to our partners at Yosemite National Park and the Mariposa Museum & History Center for helping bring this story to life.
We’ll see you September 22!
