Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
Why are tunnels not straight?
The reason for bends in road tunnels is to do with vision. The ambient light level is low in a tunnel. With a straight tunnel, a driver would be dazzled by the brightness of the light at the end of the tunnel, so curves are built so that the light level gradually increases.
