A couple months ago we gave a concert at a senior citizens' condo. While visiting over cookies afterward, I asked a few people about their favorites places to visit in Iowa. One man told me about the Keystone Arch Bridge in Elkader and showed me a beautiful painting he had purchased depicting it.
On our way home from Prairie du Chien, we stopped to see it. The Keystone Arch Bridge, at 364 feet, is the longest double arch stone bridge west of the Mississippi. Constructed in 1889 of limestone quarried locally, it stretches over the Turkey River. The bridge is in use, and there is a small park to the side with a sign telling about the bridge.
From the park, you can take a stairway down to get a closer look at the bridge and river. The building you see on the far left is a restaurant; it has a patio/porch of sorts overlooking the river for diners who would like to admire the bridge and beautiful scenery while eating. Above, I'm the barely-visible person on the left, and my dear mother is on the right.
"Marco Polo describes a bridge, stone by stone. 'But which is the stone that supports the bridge?' Kublai Khan asks. 'The bridge is not supported by one stone or another,' Marco answers, 'but by the line of the arch that they form.' Kublai Khan remains silent, reflecting. Then he adds: 'Why do you speak to me of the stones? It is only the arch that matters to me.' Polo answers: 'Without stones there is no arch.'" --Italo Calvino's Invisible Cities (1972)
