Description: The Oneonta Tunnel, located in the Columbia River Gorge in Oregon, is a historic structure that was originally constructed in 1914 as part of the Historic Columbia River Highway. This tunnel, which passes through Oneonta Bluff, was an engineering marvel of its time, designed to provide scenic views of the gorge and facilitate travel through the rugged terrain. However, it was closed to vehicular traffic in the mid-20th century due to safety concerns and the construction of modern highways. In recent years, the tunnel has been restored and repurposed as a pedestrian and bicycle path, allowing visitors to experience the breathtaking natural beauty of the area while preserving an important piece of Oregon's transportation history.
