The Bridges of Porto - a slide show

Freixo Bridge is in not so spectacular as the previous ones. The margins of the river are lower and a different type of bridge was recommended.

The bridge is, in fact, formed by two twin bridges separated by 10 centimeters, each one 18 m wide supporting a four lane way of the highway Porto-Lisbon. Only the foundations and the abutments are common.
