A gondola would probably offer sufficient value as a novelty as well as practical AT conveyance, and would be less intrusive on the skyline than a bridge. It could become an attraction unto itself, just by virtue of being the only such conveyance in the Halifax region.

It might also be considered 'less permanent' for doubters, in that it would be easier to remove than more-permanent infrastructure. Not sure on the relative costs of operation and maintenance, though. One advantage of a bridge is that it doesn't require energy (except lighting) or maintenance of constantly moving mechanical parts (one also wonders about the risk of becoming stranded over the water during a breakdown or power outage).

I still think that Halifax missed the boat (so to speak) when it didn't build a bridge during the post-war period when such an idea would have been more tenable. I agree with Dartguard that there would be a lot of push-back from people in positions of power and political influence for this to easily happen today.

Ferries are fine, and perhaps would more acceptable to the south end locals, but also have their limitations, mostly in capacity and scheduling limitations. From a climate change point of view, they also require energy to operate, like a gondola, and thus would appear to be a lower choice (on a philosophical level) for promoters of AT, as compared to a bridge.
