Marão Bridge
Viaduto Marão
Amarante, Porto, Portugal
492 feet high / 150 meters high
486 foot span / 148 meter span
2012


Completed in 2012, the Viaduto Marão tied the 1995 Rio Zêzere Bridge to become Portugal's 3rd highest span after the Despe-te que suas and Corgo Bridges. The bridge is located on the western end of a new 30 kilometer highway extension that links up Amarante to Vila Real in Northern Portugal where motorists can cross into Spain. The new route bypasses an older highway with less turns and easier grades.

The huge, single cell rectangular box girder is 29.5 meters wide with gradual banking that changes from left to right as the bridge follows an S-shaped path as it crosses the deep Marão River valley.

Also on the new autopista is the gargantuan 220 meter high Viaduto Corgo and the 105 meter high Viaduto Sordo.

There are many smaller viaducts along the steep mountain slopes between Amarante and Vila Real.

A wide satellite view of the Marão Bridge construction site shows the path of the new highway south of the older route. The bypass required the construction of several large viaducts and tunnels. The Marão tunnel entrance would be at the far right of the satellite image.



Significant progress can clearly be seen on the construction of Marão piers 2, 4, 5 and 6 while pier 3 is just above the foundation stage. You can double click on the image for a closer look.
