2019 has already witnessed a series of bridge-related milestones marked, from the world’s longest bridge nearing completion in Kuwait to the world’s largest 3D-printed concrete bridge being completed in Shanghai. As we remain fixated on the future-driven, record-breaking accomplishments of realized bridge design, "911 Metallurgist” has chosen to look back in history on some of the visionary ideas for bridges which never saw the light of day.
Whether stopped in their tracks by finance, planning, or engineering difficulties, the four bridge designs listed below embody a marriage of art and engineering too advanced for their time. From a proposal for a EuroRoute Bridge between Britain and France, to a 12-rail, 24-lane bridge across the Huston River in New York, all four designs share a common, ambitious, yet doomed vision of crossing the great divide from pen and paper to bricks and mortar.
