I had to rack my brain to think of a suitable photo for this challenge. Then I thought about our recent trip to Shropshire and thought that the Iron Bridge may provide a suitable photo. The Iron Bridge which spans the Severn River was the first cast iron bridge in the world. It first spanned the river on the 2nd July 1779. If you look closely, you can see the date.
This is my response to The Daily Post’s weekly photo challenge: “Grid.”
