... that hinges on arch bridges(example pictured) were introduced in 1858 and remain popular in modern civil engineering? "invention of the two-hinged arch: an important step forward in terms of construction and technology was reached by the engineers Couche and Salle. 1858 their wrought iron railwai bridge over the channel of St. Denis" from: Sinopoli, A. (18 December 2020). Arch Bridges. CRC Press. p. 71. ISBN978-1-000-15092-6. and "three-hinged arches: the arches are widely used in modern engineering" from: Karnovsky, Igor A.; Lebed, Olga (14 March 2010). Advanced Methods of Structural Analysis.

ALT1:... that because parts were built to two different designs the 1888 Hennepin Avenue Bridge was classed as both a two- and three-hinged bridge? "Because it was built in two unique longitudinal halves by two different bridge companies , the bridge has historic engineering as well transportation significance . The earlier - constructed north arch ribs are three- hinged . The south ribs were added as two- hinged arches , making the bridge both a two- and three- hinged arch." from: Hennepin Ave Mississippi River Bridge Replacement, Minneapolis: Environmental Impact Statement. 1986. p. 106.
Overall: Overall, this dyk satisfies all requirements, including those for image use, and I would say it is good to go. I would definitely choose the main hook over the alt. JJonahJackalope (talk) 20:39, 22 October 2021 (UTC)
