Jelaskan Kendala-kendala dari Jalan Raya Trans Global

As with all major public works projects, funding is an issue. Large international projects such as the Bering Strait crossing, Japan–Korea Undersea Tunnel, dan Terowngan Gibraltar require not only great engineering effort, but also tremendous diplomacy to ensure that costs and benefits would be shared equitably. Other modes of transport, by air and sea, are already available. In addition, geological study must be done to ensure that the local plate tectonics would be compatible with the proposed tunnels.

Despite the hypothetical benefits of a global transport link, there is currently no publicised reasoning that would justify the massive financial cost of such a proposal.
