The Travel and Transportation Building is the most striking architectural and engineering achievement at a "Century of Progress." From twelve steel towers is suspended a gigantic dome 125 feet above the ground, called "the dome that breaths", because the slightest sound echoes and re-echoes, as it travels across the interior. Here, creaky wagons of 1833, the first locomotives and automobiles, and their present modern successors tell a vivid story of mans progress in transportation.
