For anyone not keeping an eye on SDOT’s Flickr page, there are some remarkable photos of ongoing construction progress on King Street Station, which is currently undergoing extensive seismic and restoration work. As a bonus, there are even historic photos of what once was. The waiting area for Amtrak passengers has been temporarily relocated to a narrow corridor under the west canopy outside of the station. Meanwhile, select demolition and seismic retrofits continue in the main waiting room, which will undoubtedly be the centerpiece of the station interior, upon completion.
Aside from restoration work itself, I think the biggest problem still haunting the station is its integration into the King Street hub, of which only so much can be solved by wayfinding. While we can imagine ways for grandiose improvement without so much as a penny to fund them, the need still persists and will continue to do so as we build up our local, regional, and interstate rail networks into the future.
