Carlin Tunnel
The Carlin Tunnel is a collective name for a set of four tunnel bores in the Humboldt River's Carlin Canyon, east of Carlin in Elko County, Nevada, United States. The two railroad bores were constructed for different purposes at different times, while the two highway bores were constructed concurrently, all with the goal of bypassing a sharp bend in the river. Currently, two of the bores carry Interstate 80, while the other two bores carry Union Pacific Railroad's Overland Route and Central Corridor. Bridges over the Humboldt River are adjacent to both portals of three tubes, including the two freeway bores and one of the railroad bores.
