Took 22 months to build
One of the bridges over the Duero, built to link Porto to the other side of the river. It's a National Monument, was designed by Gustave Eiffel, is made of iron and is very similar to Luis I bridge, but differs in that it has no lower footbridge. It took 22 months to build and was opened by King Ludwig I and his wife Maria Pia (hence its name) in 1877. It was the first bridge that allowed a rail connection between the banks of the Duero River. From the cruise ship you get a different perspective from the bottom.
