Under the Ma-20: Vision with a Catch — How Realistic Is Palma's Green Ring?

Answer

Could Palma really put the Ma-20 underground and turn it into a green ring?

Yes, the idea is technically possible, but it would be a major and expensive project. The biggest questions are how to finance it, how to manage traffic during construction, and whether the surface space would stay public after the tunnel is built.
