Big Bertha has hits the Streets!

Big Bertha tells the incredible story about Bertha—the massive tunnel boring machine that successfully constructed a road tunnel under the city of Seattle— the longest and widest one in the contiguous United States. Brought to life in vibrant and engaging illustrations by Katy Wu, this story will captivate kids who are fascinated with big machines and how they work.

“Fueled by the drama of a subterranean breakdown and a race to the finish line, this big-machine tale is anything but boring.”
