While we're on it (and because my brother has just had a delivery to Casablanca), a bridge (or even a tunnel?) that would connect Southern Spain to Northern Morocco would be entirely something else, it would better integrate Morocco's economy into the EU (and vice-versa) while strengthening the ties between Europe and Africa. Not sure though how much a project like that would cost, or if it's even possible. I wouldn't say it is impossible, but my understanding is that it is decidedly non-trivial due to geography and geology: https://en.wikipedia.org/wiki/Strait_of_Gibraltar_crossing https://en.wikipedia.org/wiki/Strait_of_Gibraltar_crossing
