it makes the lives of a few rich people better as they can commute to their yachts better, but that's about it
sf would have been completely fine as a city without this bridge
ferries already existed, as well as other ways to get to the areas north of the city.
the main issue with this bridge is that it is the enemy of better, and a bridge/tunnel with forward thinking infrastructure and transit can now never be built, now that we have this antiquated garbage bridge built, merely for the myth of car ownership
the civil planning doesn't even extend to the rest of the city, it's merely plopped down onto an arbitrary section of it.
it would have been better to not have been built at all. a more ugly bridge built later on wouldn't have had the nimbys we have today, and could have been torn down and retrofitted without it being sacrilegious
