In the context of this artwork, discuss the Langlois Bridge of the Background.

The Langlois Bridge was one of the crossings over the Arles to Bouc canal. The double-beam drawbridge was built in the first half of the 19th century to expand the network of canals to the Mediterranean Sea. Locks and bridges were built, too, to manage water and road traffic. Just outside Arles, the first bridge was the officially titled "Pont de Réginel" but better known by the keeper's name as "Pont de Langlois". In 1930, the original drawbridge was replaced by a reinforced concrete structure which, in 1944, was blown up by the retreating Germans who destroyed all the other bridges along the canal except for the one at Fos-sur-Mer, a port on the Mediterranean Sea. The Fos Bridge was dismantled in 1959 with a view to relocating it on the site of the Langlois Bridge but as a result of structural difficulties, it was finally reassembled at Montcalde Lock several kilometers away from the original site.According to letters to his brother Theo, van Gogh began a study of women washing clothes near the Langlois Bridge about mid-March 1888 and was working on another painting of the bridge about 2 April. This was the first of several versions he painted of the Langlois Bridge that crossed the Arles canal.Reflecting on van Gogh's works of the Langlois Bridge Debora Silverman, author of the book Van Gogh and Gauguin: The Search for Sacred Art comments, "Van Gogh's depictions of the bridge have been considered a quaint exercise in nostalgia mingled with Japonist allusions." Van Gogh approached the making of the paintings and drawings about the bridge in a "serious and sustained manner" with attention to "the structure, function, and component parts of this craft mechanism in the landscape."
