Experience what’s out there
21 October, 2019 A tunnel is roughly defined, when a definition can be narrowed down at all. A drive time radio host sharing the traffic report will refer to a surface-level enclosed road as a tunnel, or a pedestrian walkway in a culvert, or even an eight lane overpass.

The specific numbers aren’t as important, though, as what they signify—the need to excavate without disrupting the surface.
