The 140-year history of IHI is expressed through the idea of bridges being built as lines connecting and extending onward. Beginning with an old blueprint, the animation starts as those lines stretch out, and as the years pass, bridge design techniques evolve from 2D drawings to 3D. The bridges from each era are assembled in step with that evolution, and in the end, the flourishing city that emerges beyond the completed bridge is shown in a pop-style animation.
