1926 Plougastel Bridge – Plougastel, France
Innovation: Plougastel Bridge
Location: Plougastel, France
By: Albert-Louppe and Eugene Freyssinet
In 1926, Albert-Louppe and Eugene Freyssinet designed a bridge over the Elorn River near Brest, France called Plougastel Bridge, also know as, Albert-Louppe Bridge, which connects Plougastel-Daoulas and Le Relecq-Kerhuon. Construction started in 1926 and was completed on October 9, 1930, however, part of it was destroyed by the German army in 1944. Repair on the bridge started shorty after and continued for 5 years, in which, the bridge was widened and reconstructed. After the reconstruction the bridge was 30 feet (9 meters) wide, 90 feet (27.5 meters) high, and 2913 feet (888 meters) in length, containing three major archs each spanning 617 feet (188 meters) with fixed, double deck structure. All this was possible with one material reinforced concrete, which held the bridge in place and made it possible for this great span to be covered.
