Would an ITT Make Sense for the WSLE?
Iirc, a Immersed Tube Tunnel was floated as an idea to replace the West Seattle Bridge when it developed structural damage back in 2020.
It was discarded as an idea for cars, but: I was wondering if it would make sense for trains.
Has anything like this been considered?
