The cost of constructing a tunnel like the Eurotunnel versus building a bridge depends on several factors, including the location, the terrain, the environmental conditions, and the materials used. However, in general:

  1. Tunnels tend to be more expensive than bridges due to:
    • The complexity of excavation and tunneling technology required.
    • The need for ventilation, lighting, drainage, and safety features.
    • The challenges of working underground, especially in difficult geological conditions.
    • High labor and equipment costs.
    • Increased risk and potential for unforeseen challenges during construction.
  2. Bridges, on the other hand, may be cheaper under certain circumstances, but:
    • They require large-scale foundations, especially in deep or wide bodies of water.
    • The construction of piers, pylons, and support structures can be costly, especially in challenging terrains.
    • Bridges can be more expensive if environmental impact assessments and mitigation measures are stringent.

Which is cheaper?

  • Bridges are generally more cost-effective when spanning relatively shallow water or stable land. They may be less costly in areas where the terrain is suitable for bridge construction.
  • Tunnels are usually the more expensive option when traversing deep bodies of water, mountainous terrain, or urban areas where surface space is limited.

It would be essential to evaluate the specific site conditions (geology, hydrology, environmental considerations) to make a more accurate cost comparison.
