Bridges and Tunnels

Bridges and Tunnels is a free, self-paced learning path in Engineering & Robotics, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify fundamental forces acting upon structural bridge designs; distinguish between cut-and-cover and bored tunnel methods; evaluate material strength for large infrastructure projects.

Conductor

The Conductor

All aboard for a journey beneath the earth and across the tallest spans. We explore how steel and stone unite to bridge the gaps in our world.
