Big Bend Tunnel

Big Bend Tunnel is a historic railway tunnel located in California’s Sierra Nevada, near Lake Tahoe. Built in the 1920s, it was designed to carry train routes through the mountains, improving transportation and trade. The tunnel spans about a mile and features a large, curved section known as the "Big Bend," which allowed trains to navigate steep terrain safely. Today, it is part of the historic rail corridor and attracts visitors interested in its engineering significance and scenic views. The tunnel exemplifies early 20th-century engineering efforts to connect remote regions through challenging mountainous landscapes.
