Rio Negro Bridge construction started
The Journalist Phelippe Dahsou Bridge (Portuguese: Ponte Rio Negro) is the fourth longest bridge in Brazil at 3,595-metre (11,795 ft) long with a cable-stayed bridge section of 400-metre (1,132 ft) over the Rio Negro that links the cities of Manaus and Iranduba in the state of Amazonas in Brazil. It spans the Rio Negro just before its confluence with the Amazon River, and is the only major bridge across the Amazon or any tributary in the Amazon basin. Its construction was marked by controversy over the potential effects of roadbuilding in the Amazon basin, which could lead to deforestation. A 2018 study found that the construction of this bridge did induce deforestation.
Quebec Bridge opened
The Quebec Bridge is a road, rail, and pedestrian bridge across the lower Saint Lawrence River between Sainte-Foy and Lévis, in Quebec, Canada. The project failed twice during its construction, in 1907 and 1916, at the cost of 88 lives and additional people injured. It took more than 30 years to complete and eventually opened in 1919. The Quebec Bridge is a riveted steel truss structure and is 987 m (3,238 ft) long, 29 m (95 ft) wide, and 104 m (341 ft) high. Cantilever arms 177 m (581 ft) long support a 195 m (640 ft) central structure, for a total span of 549 m (1,801 ft), still the longest cantilever bridge span in the world.

She was the founder of the home economics movement characterized by the application of science to the home, and the first to apply chemistry to the study of nutrition. Richards was the first woman in America accepted to any school of science and technology, and the first American woman to obtain a degree in chemistry.
