Mount Baker Ridge Tunnel (new bore)

The Mount Baker Tunnel or Mount Baker Ridge Tunnel carries Interstate 90 and Link light rail's 2 Line under the Mount Baker neighborhood of Seattle, Washington. It is actually a group of three tubes that carry eight lanes of freeway traffic, plus a separate path for bicycles and pedestrians, and two tracks for Link light rail. The original tubes are twin tunnel bores completed in 1940 and rehabilitated in 1993.
