Tallest Bridge in the World

Located in Southern France, the Millau Viaduct is the tallest bridge in the world. Constructed in three short years, the bridge is an engineering and architectural marvel. At its highest point, the bridge soars 343 meters (1,125 ft) above ground, that’s 19 meters (62 ft) taller than the Eiffer Tower! Check out the incredible photographs below along with a timeline of the project’s major milestones and notable records and figures.
