Costs went 80% over budget for construction, in real terms, and 140% over for financing. Those costs had to be covered and debt had to be serviced during construction, while revenues were still years in the future. Revenues were a fifth of what had been estimated, resulting in the tunnel's first insolvency.
The mountain material is solid and strong enough not to collapse the hole, or the hole is lined with reinforcement that transfers load from one side to the other. This is now iron/steel rings or reinforced concrete. Tunnel boring machines build the liners as they progress, and push forward using the last ring.
Dover - Calais ferry tickets start at around €36 for foot passengers and at about €80 for passengers who travel with a vehicle.
