The Spanish Bridges series continues with two souvenir sheets dedicated to the Roman Bridge in Mérida (Badajoz), and the Pilar Bridge in Zaragoza.
The Roman bridge in the city of Mérida stands on the Guadiana river as part of the archaeological site of the ancient Augusta Emerita, the name by which the town was known in ancient times. It was built in the 1st century to facilitate communications with Hispania Baetica and give access to the city after the settlement of the Roman legions in town. It is 792 meters long with 60 round arches and it is considered to be the longest bridge of antiquity. It is built with a concrete core made of materials from the river and covered with granite padded blocks. It was originally divided into three distinct sections. The location where the bridge was raised was chosen taking into account the lower flow in that part of the river and because of the fact that the course was divided into two surges with an island in the middle which served to support the bridge. Over two thousand years of flooding and overflowing of the river have led to several restorations although the bridge still keeps its original construction in the part closest to the city known as the Humilladero.
The souvenir sheet depicts a view of the Roman bridge with its many arches.
