In April of 2017, Bertha, the massive tunnel-boring machine successfully completed digging a nearly 2 mile deep-bore tunnel under Seattle. The tunnel will carry traffic from the Alaskan Way Viaduct, which had been damaged and deemed seismically unsafe after an earthquake. The tunnel will be much less intrusive than the wall-like Viaduct structure, which cuts Seattle off from its waterfront, and the tunnel, new surface street, and transit will take care of the Viaduct’s 110,000 vehicles per day.Why did Seattle move the highway from above ground to below ground? What we're the replacement options considered? How did Seattle settle on the deep bore tunnel, one of the most expensive options possible, as a replacement for the Viaduct? What was that process like?

Some cities are incredibly dense, filled with towering skyscrapers. Others are spread out, filled with single family homes. Which is better? Is there a best density? Spoiler: it has something to do with transportation.

Cities have a profound impact on the natural environment due to emissions, sprawling land use, water pollution and more. But people living in dense urban areas also pollute less and are overall better for the environment than people living in the suburbs. How can cities be made more sustainable and attractive for everyone?

Watch this video on Nebula: https://nebula.tv/videos/citybeautiful-is-san-franciscos-new-transit-center-worth-it
San Francisco opened the Salesforce Transit Center in 2019, and currently serves buses only. It does not connect to local transit trains and will not serve longer-distance trains until at least 2033. Does that make this station a failure? Or maybe it's forward-thinking?

How do you create a memorial that speaks to the victims families, but also to those who didn’t experience the event at all? How do you design a memorial that will carry on the significance of what happened to people 50 or 100 years from now? And how do you do all of that while also creating a functional public space in the heart of Lower Manhattan?
