Deep tunnels. Incredible engineering beneath your feet!\nTunnel engineering is making headlines right now. In August 2026, Amtrak completed the first major rehabilitation phase of New York’s 116-year-old East River Tunnel, a vital system used by about 450 trains every day. In Baltimore, crews are also preparing for a major new rail tunnel project that will eventually send enormous tunnel-boring machines underground.\nBut how do engineers actually build a tunnel beneath a crowded city, a mountain, or even a river without everything above collapsing?\nIn Kid Explorers: Dig Deep! How the World’s Greatest Tunnels Are Built, curious 10-year-old Marcus Reed follows the incredible engineering journey from the first geological surveys to the thrilling moment of breakthrough.\nYoung readers will discover how engineers study rock and soil, guide enormous tunnel-boring machines, remove tons of excavated material, install concrete lining rings, control groundwater, ventilate deep underground spaces, and build emergency systems that keep modern tunnels safe.\nAlong the way, explore remarkable real-world engineering beneath rivers, crowded cities, and the Swiss Alps while discovering the science behind some of the world’s greatest tunnels.\nWhether reading independently, together as a family, or as part of a homeschool STEM study, Dig Deep! turns civil engineering into an underground adventure.\nGrab your hard hat and discover the hidden engineering world beneath your feet!\u003cbr\u003eASIN: B0HGCW38DB\u003cbr\u003eVSKU: BVV.B0HGCW38DB.G\u003cbr\u003eCondition: Good\u003cbr\u003eAuthor\/Artist:Jamieson, Kay\u003cbr\u003eBinding: Paperback\u003cbr\u003e\u003cb\u003eNote:\u003c\/b\u003e Any images shown are stock photographs and product may differ from what is shown.  \u003cbr\u003e\u003cb\u003eCondition Notes\u003c\/b\u003e: The item shows wear from consistent use, but it remains in good condition and works perfectly.
