John A. Roebling Bridge The Roebling Bridge between Covington, Kentucky and Cincinnati, Ohio opened to traffic on January 1, 1867. Its central span of 1057 feet was the longest in the world. The bridge was recognized as a National Historical Landmark in 1975. The bridge was designated as a National Civil Engineering Landmark in 1982. #Cincinnati

Alexandre Gustave Eiffel né Bönickhausen (15 December 1832 – 27 December 1923) was a French civil engineer, architect and freemason.[5][6][7][8][9][10] A graduate of the École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France.

U.S. Route 1 (US 1) in Florida runs 547 miles (880 km) along the state's east coast from Key West to its crossing of the St. Marys River into Georgia north of Boulogne, and south of Folkston. US 1 was designated through Florida when the U.S. Highway System was established in 1926. The road is maintained by FDOT. This is a section in the Florida Keys.

End of October 2004 : building phase is completed. Before the grand opening planned on December 14th, workers are going to take down the temporary structures (in red) and link the roadway to each motorway rim.

Y is for yield strength

Hooke's law only holds for some materials under certain loading conditions. Steel exhibits linear-elastic behavior in most engineering applications; Hooke's law is valid for it throughout its elastic range (i.e., for stresses below the yield strength). For some other materials, such as aluminium, Hooke's law is only valid for a portion of the elastic range. For these materials a proportional limit stress is defined, below which the errors associated with the linear approximation are negligible.
