The Pedro and Inês footbridge was designed by the engineers Cecil Balmond and Adão da Fonseca and was built under the Polis Programme, to connect the left and right banks of the Mondego River. It was inaugurated on the 26th November 2006.
The bridge is 275 meters long and four meters wide, with a eight meter wide square in the middle. The footbridge is made of wood and the protection guards have glass in four different colours: yellow, blue, green and pink. The bridge has already been considered an icon of architecture and was classified by several specialists as ?a daring achievement in engineering?, and considered a ?revolutionary but elegant structure?.
