Celeste Tunnels Underground follows the journey of a civil engineer based in Dallas, Texas who is on a mission to solve the issue of traffic congestion. After researching ways to do this, she lands on building a tunnel and travels across the world to see projects that are currently in use and those under construction. Back in Dallas, Celeste and her team get to work on this important task and eases traffic in the busy city.

With a nod to famous tunnel projects like the English Channel Tunnel and Boston's Big Dig, this fun and educational story encourages children from diverse backgrounds to pursue careers in construction and engineering while opening their eyes to the fascinating world of tunnels.
