A look at another stalled attempt to get rapid transit up and running in Seattle, this time from 1970. A lot of the proposed alignments look very familiar, but they are often constrained by Seattle’s difficult geography. I see that they were thinking of running rapid transit over the I-90 floating bridge – quite the engineering feat even now, let alone over 40 years ago. Even now, it’ll be the first light rail track travelling across a floating bridge in the world when built.

A beautiful illustration style, though, with a restrained but useful three-colour palette (black, cyan and orange). I wish there were more planning maps like this these days.
