Spring Garden Tunnel

The Spring Garden Tunnel is a railway tunnel located at Spring Garden, California. At long, it is the longest of 34 tunnels on the Feather River Route and crosses under the drainage divide between the East Branch North Fork Feather River and the Middle Fork Feather River.

History

The Western Pacific Railroad built the tracks along the Feather River in 1909 to complete the Feather River Route, a San Francisco Bay Area to Salt Lake City route competing with the Southern Pacific's route over Donner Pass.
While significantly longer, the Feather River Route was preferred by some over the Donner Pass route over the Sierra Nevada mountains, because the former's summit under Beckwourth Pass is at a lower elevation and most of the route follows a gentler grade along the Feather River.
The tunnel was designated one of Plumas County's "7 Wonders of the Railroad World," and the north portal is west on Railroad Street, then SSE along a fair-condition dirt road from Spring Garden, California.
