Milepost 31

So, we’ve all heard about Bertha and the tunneling project for State Route 99, but there’s more to know.

The Milepost 31 Information Center has been created so folks can learn more about Pioneer Square, and this particular Milepost. Not only can you learn about the tunneling project, you can also see how natural forces, man-made advancements, and people themselves have impacted the ground you stand on at the center. From artifacts, information, speakers and more, you’ll come away with a whole new appreciation of Seattle’s Pioneer Square and waterfront.
