Successful Grand Opening of the Sutro Tunnel Extension

The Sutro Tunnel was echoing with sounds of the past and present on Saturday during a special Sutro Social & Cards in the Cavern affair. Friends of Sutro Tunnel Charity and the Dayton Area Chamber of Commerce welcomed more than 300 people to celebrate the official opening of the tunnel extension for the summer 2025 season. The public can now safely walk 200 feet into the accurately restored adit and gaze down the unrestored section that Simerson Construction will continue work on this fall.
