History
Early projects 1802
In 1802, French mining engineer Albert Mathieu-Favier put forward the first ever design for a cross-Channel fixed link based on the principle of a bored two-level tunnel: the top one, paved and lit by oil lamps, to be used by horse-drawn stagecoaches ; the bottom one would be used for groundwater flows.

In 1803, the Englishman Henry Mottray unveils another project for a cross-Channel fixed link: a submerged tunnel made of prefabricated iron sections.
