Tunneling the Ring Road: One Billion, Many Questions

Answer

How much could the Palma ring road tunnel cost?

The current proposal has been discussed at a cost of up to one billion euros. That figure is only a rough political estimate and does not yet replace a proper feasibility study or audited budget. It also does not include the long-term costs of ventilation, drainage, safety systems and maintenance that a tunnel would need.
