Book Overview

This incredible story about Bertha, the massive tunnel boring machine that successfully constructed the longest and widest road tunnel in the contiguous United States, under the city of Seattle, brought to life in vibrant and engaging illustrations, will appeal to kids ages 7-10 fascinated with big machines and how they work.

In 2013, construction crews raced to replace a crumbling elevated highway along Seattle's waterfront with a double-decker tunnel running almost two miles under the city. This is the story of Bertha, the mammoth and complex tunnel boring machine that simultaneously dug and built the tunnel, and Deputy Project Manager Greg Hauser and his dedicated crew.

Kids interested in engineering and how machines function will love learning about the tunnel boring machine, how it worked, and how Bertha's crew solved problems that arose along the way to ultimately construct an amazing, earthquake-safe highway under the city.

In addition to the narrative story the book includes additional information about Bertha and this fascinating engineering feat, including:
